Generic Name
Glatiramer (glah-TYE-ram-er)
Brand Name  Copaxone
Type of Drug
Relapsing-remitting multiple sclerosis (MS) therapy.
Prescribed For  MS.
General Information
Glatiramer is a mixture of several amino acids. It is thought to work by modifying the immune processes responsible for MS. In studies, people who took the drug for over a year were twice as likely to be relapse-free as those who took a placebo (sugar pill).
Cautions and Warnings
Do not use this drug it you are allergic or sensitive to any of its ingredients or to mannitol.
About 10% of people who self-administer glatiramer experience a post-injection reaction with symptoms that include flushing, chest pain, heart palpitations, anxiety, breathing difficulties, closing of the throat, and an itchy rash. These symptoms usually go away without treatment. This reaction generally occurs after several months of drug therapy, though it may occur earlier.
About 21 % of the people who took glatiramer in drug studies had chest pain, but the exact relationship of this pain to use of glatiramer could not be determined. Report any chest pain to your doctor at once.
Glatiramer may make you more sensitive to sunlight.
Because it interferes with immune response, glatiramer may increase your risk of developing infections and tumors.
Glatiramer may interfere with kidney function.

Pioglitazone Hydrochloride + Glimepiride Duetact
Rosiglitazone Maleate + Metformin Hydrochloride
Nnndamet
Rosiglitazone Maleate + Glimepiride Avandaryl
Prescribed For  Type 2 diabetes.
General Information
The glitazones reduce the amount of sugar produced by the liver and increase insulin sensitivity of muscle, liver, and fat cells. They may also help to control blood-fat levels, which are often elevated in diabetes. Glitazones work by affecting genes responsible for controlling the use of sugar and fat in the body, making cells more sensitive to insulin. They are effective for people with type 2 diabetes, whose cells do not respond well to insulin. Glitazones only work when insulin is present. They do not increase the amount of insulin made in the pancreas. Glitazones can be used alone or combined with other diabetes drugs. Studies have indicated that taking rosiglitazone can delay or prevent type 2 diabetes in people with pre-diabetes.
Cautions and Warnings
Do not take these drugs if you are sensitive or allergic to any of their ingredients or to related drugs. Glitazones may cause fluid retention, worsening or leading to heart failure. Some studies have indicated the risk of heart attack may be increased in people taking rosiglitazone. Other studies have shown that pioglitazone decreases the risk of heart attack. The effects of these drugs on the heart are still being investigated.
Glitazones are broken down in the liver; people with liver disease should not take them. Liver enzyme monitoring is recommended for all people taking a glitazone. People taking pioglitazone and rosiglitazone have experienced liver failure, though no direct causal effect of the drug has been established.
Glitazones may raise blood levels of cholesterol and other blood fats.
These drugs can trigger ovulation. Premenopausal women who are not ovulating may be at risk of becoming pregnant.
Glitazones can cause weight gain, which increases with dosage.
Rosiglitazone may increase the risk of broken bones in the hands, arms, or feet.
Women may achieve maximum benefit with smaller dosages.
Possible Side Effects
Pioglitazone
In studies, the side effects of pioglitazone were about the same as those for a placebo (sugar pill).
Possible Side Effects (continued)

For additional side effects of Avandamet, see Metformin (page 696). For additional side effects of Avandaryl, see Sulfonylurea Diabetes Drugs (page 1065).
Drug Interactions
•    Mixing gemfibrozil (for very high triglycerides) with a glitazone increases the amount of the glitazone absorbed into the body. A reduction in the dose of the glitazone may be needed if you start taking gemfibrozil.
•    Rifampin can reduce the amount of a glitazone that is absorbed by the body, possibly leading to higher blood sugar levels.
•    Ketoconazole may significantly increase the amount of pioglitazone in the body. Other drugs that may have a similar effect but have not yet been studied include itraconazole, erythromycin, calcium channel blockers, corticosteroids, cyclosporine, protease inhibitor anti-HIV drugs, tacrolimus, triazolam, and trimetrexate.
•    Mixing pioglitazone with atorvastatin may reduce the amount of either drug in the body.
•    Pioglitazone may reduce the effectiveness of contraceptive drugs containing norethindrone and ethinyl estradiol. Higher-dose contraceptives or another contraceptive method may be needed.
•    Pioglitazone may stimulate the breakdown of other drugs also metabolized in the liver.
•    Taking rosiglitazone and insulin may increase the risk of fluid retention and heart failure.
For additional drug interactions for Avandamet and ACTOpius Met, see Metformin (page 696). For additional drug interactions for Avandaryl and Duetact, see Sulfonylurea Diabetes Drugs (page 1065).
Food Interactions

The information in this profile also applies to the following drug:
Generic Ingredients: Bismuth Subcitrate Potassium + Metronidazole + Tetracycline
Pylera
Type of Drug  Antibacterial combination.
Prescribed For  Duodenal ulcers.
General Information
Research has shown that the bacterium Helicobacter pylori is usually present in ulcer disease and some forms of gastritis. Drugs used to treat the H. pylori infection are prescribed along with a drug that alleviates ulcer symptoms by blocking stomach acid. There are a variety of approaches to treating ulcers by using combinations of various antibiotic and acid-blocking drugs. Helidac combines 3 drugs with antibacterial or antibiotic action. This combination generally works by disrupting the cell walls of the bacterium and interfering with its ability to make proteins or duplicate
itself. It is often prescribed together with ranitidine, cimetidine, or another acid Mocker. Other treatments use other drug comb-
nations.
Cautions and Warnings
Do not take Helidac if you are allergic or sensitive to any of its
ingredients.
Do not take Helidac if you have severe liver or kidney disease. People with less severe liver disease may require a reduced dosage.
Rarely, bismuth causes severe nervous system toxicity. Symptoms go away after the drug is stopped.
Bismuth subsalicylate can cause dark stools or darkening of the tongue. This darkening of stools is not dangerous; however, be aware that blood in the stool often manifests as blackening of the stool.
Children or teenagers who have or are recovering from chickenpox should not use Helidac because it contains a small amount of salicylate, which is related to aspirin. Children or teenagers who take aspirin or a salicylate may develop Reye’s syndrome: symptoms include nausea and vomiting.
Bismuth can also cause ringing in the ears, especially if taken along with another aspirin-containing drug.
Metronidazole can cause convulsive seizures and nervous system effects including numbness or tingling in the arms, legs, hands, or feet. The risk of developing these effects increases with dosage and duration of use. Call your doctor at once if you experience any of these effects.
Metronidazole should be taken with caution by people who have had blood diseases or nervous system disorders, such as seizure disorders.
Candida infections may worsen while you are taking metronidazole.
Other infections, called superinfections, can develop while you are taking tetracycline. If this happens, your doctor will discontinue Helidac and prescribe a different drug to treat your H. pylori infection, ;a% %0M as another drug to treat the superinfection.
Tetracycline should not be used in children under age 8 due to the risk of tooth discoloration.
People taking tetracycline can develop pseudotumor cerebri (pressure inside the brain), the symptoms of which are usually headache and blurred vision. Symptoms usually go away when the drug is stopped, but permanent damage can result.
Tetracycline may increase your sensitivity to the sun; use sun-
screen and wear protective clothing.
Tetracycline may make contraceptive drugs less effective. Another or additional forms of contraceptive should be used.
Possible Side Effects
?    Most common: nausea and diarrhea.
?    Less common: abdominal pain, blood in the stool, head-
ache, anal discomfort, appetite loss, dizziness, tingling in
the hands or feet, vomiting, muscle weakness, constipa-
tion, sleeplessness, pain, and respiratory infections.
For more information on possible side effects, see Metronidazole, page 718, and Tetracycline Antibiotics, page 1103.
Drug Interactions
•    Tetracycline antibiotics, which are bacteriostatic, may interfere with the action of bactericidal (bacteria-killing) agents such as penicillin. You should not take both kinds of antibiotics for the same infection.
•    Antacids, mineral supplements, and multivitamins containing bismuth, calcium, zinc, magnesium, and iron can reduce the effectiveness of tetracycline. Separate doses of your antacid, mineral supplement, vitamin with minerals, or sodium bicarbonate and Helidac by at least 2 hours.
•    Tetracycline and metronidazole may each increase the effect of anticoagulant (blood-thinning) drugs such as warfarin. An adjustment in the anticoagulant dosage may be required.
•    Cimetidine can increase metronidazole blood levels. Your metronidazole dosage may be reduced if you are also taking cimetidine.
•    Tetracycline should not be used with methoxyflurane due to the risk of a toxic interaction.
•    Tetracycline may increase blood levels of digoxin in a small number of people, leading to possible digoxin side etezks. (” %kjMt pelop% 1his’interaction with digoxin can occur for months after tetracycline has been stopped. If you are taking this combination, watch carefully for digoxin side effects and call your doctor if any develop.
•    Tetracycline may reduce diabetic insulin requirements. If you are using this combination, be sure to carefully monitor your blood-sugar level.
•    Tetracycline may increase or decrease lithium blood levels. Metronidazole raises lithium blood levels, effects, and toxicity.
•    Combining alcohol and metronidazole may cause abdominal cramps, nausea, vomiting, headaches, and flushing. Modification of the taste of alcohol has also been reported. Metronidazole should not be used if you are taking disulfiram (a drug used to maintain alcohol abstinence) because the combination can cause confusion and psychotic reactions.
•    Phenobarbital and other barbiturates can decrease metronidazole’s effectiveness.
•    Drugs that cause nervous system toxicity, such as mexiletine, ethambutol, isoniazid, lincomycin, lithium, pemoline, and long-term high-dose pyridoxine (vitamin 136) should not be taken with metronidazole because of the increased risk of nervous system side effects.
•    Metronidazole may increase phenytoin blood levels and the risk of phenytoin side effects; your doctor may need to adjust your phenytoin dosage.
Food Interactions
Do not take this drug with milk or dairy products. Helidac should be taken with meals and at bedtime.
Usual Dose

All 3 in(aMd1K1t ,in Helidac can be dangerous if taken in overdose, but salicylate poisoning is the most threatening. Symptoms of salicylate toxicity are rapid or heavy breathing, nausea, vomiting, ringing or buzzing in the ears, high fever, lethargy, rapid heartbeat, and confusion. Other more serious symptoms may develop. Take the victim to a hospital emergency room at once. ALWAYS bring the prescription bottle or container.
Special Information
Tetracycline can reduce the effectiveness of contraceptive drugs; you should use backup contraception while taking Helidac. Breakthrough bleeding is also possible.
Bismuth can cause a temporary darkening of your tongue or stool. This is a harmless effect. Stool darkening should not be confused with blood in the stool, which turns it black.
Avoid alcohol while taking Helidac and for 1 day after you stop taking it.
Call your doctor if you develop ringing in the ears. This can be a sign of salicylate toxicity from the bismuth.
If you forget a dose, take it as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule. Never take a double dose.
Special Populations
Pregnancy/Breast-feeding: Helidac should not be taken by pregnant women. Tetracycline affects bone and tooth development in the fetus.

Type of Drug
Allergy preventive and antiastk)m-aft_.
Prescribed For
Prevention of severe allergic reactions, including asthma, runny nose, and mastocytosis; also prescribed for food allergies, eczema, dermatitis, chronic itching, and hay fever. It may be used to treat and prevent chronic inflammatory bowel disease. The eyedrops are used to treat conjunctivitis (pinkeye) and other eye irritations.
General Information
Unlike antihistamines, which work against histamine that has been released into the system, cromolyn sodium prevents allergy, asthma, and other conditions by stabilizing mast cells, a key component in any allergic reaction because they release histamine. Cromolyn prevents the release of histamine and other chemicals from mast cells. The drug works only in the areas to which it is applied; only 7-8% of an inhaled dose and 1 % of a swallowed capsule is absorbed into the blood. Even the oral capsules, which one would normally expect to be absorbed into the blood, treat only gastrointestinal -tract allergies. Cromolyn products must be used on a regular basis to be effective in reducing the frequency and intensity of allergic reactions.
Cautions and Warnings
Do not take cromolyn if you are allergic or sensitive to any of its ingredients. Rarely, people have experienced severe allergic attacks after taking cromolyn.
cromolyn should never be used to treat an acute allergy attack. It is intended only to prevent or reduce the number of allergic attacks and their intensity. Once the proper dosage level has been established for you, reducing that level may result in a recurrence of attacks.
People with kidney or liver disease require reduced dosage.
Cough or bronchial spasm may occasionally occur after the inhalation of a cromolyn dose. Severe bronchospasm is rare.
cromolyn aerosol should be used with caution in people with abnormal heart rhythm or diseased coronary blood vessels because of a possible reaction to the propellants used in the product.
Possible Side Effects

Cyclobenzaprine overdose may cause confusion, loss of con- centration, hallucinations, agitation, overactive reflexes, fever or vomiting, rigid muscles, and other side effects of the drug. It may also cause drowsiness, low body temperature, rapid or irregular heartbeat and other kinds of abnormal heart rhythms, heart failure, dilated pupils, convulsions, very low blood pressure, stupor, coma, and sweating. Overdose victims must be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Cyclobenzaprine causes drowsiness, dizziness, or blurred vision in more than 40% of people who take it, which may interfere with the ability to perform complex tasks like driving or operating equipment. Avoid alcohol, sedatives, and other nervous system depressants because they can enhance sedative effects of cyclobenzaprine.
Call your doctor if you develop rash; hives; itching; urinary difficulties; clumsiness; confusion; depression; convulsions; difficulty breathing; irregular heart rate; chest pain; fever; yellowing of the skin or whites of the eyes; swelling of the face, lips, or tongue; or any other persistent or bothersome side effect.
If you forget a dose of cyclobenzaprine, take it as soon as you remember. If you take cyclobenzaprine once a day and it is almost time for your next dose, skip the one you forgot and continue with your regular schedule. If you take cyclobenzaprine twice a day and it is almost time for your next dose, take 1 dose as soon as you remember, another in 5 or 6 hours, and then go back to your regular schedule. If you take cyclobenzaprine 3 times a day and it is almost time for your next dose, take 1 dose as soon as you remember, another in 3 or 4 hours, and then go back to your regular schedule. Never take a double dose.
Special Populations
Pregnancy/Breast-feeding: -The safety of cyclobenzaprine in ‘jftg)T)1 women has not been established. Cyclobenzaprine should only be used if the potential benefits outweigh the risks.
It is not known if cyclobenzaprine passes into breast milk, but antidepressants with a similar chemical structure do pass into breast milk. Nursing mothers who must take this drug should consider using infant formula.
Seniors: Seniors are more likely to be sensitive to the effects of cyclobenzaprine. Use of Amrix in particular is not recommended
in the elderly.

Generic Name
Cyclosporine (sye-kim-SPQR-in)
Brand Names
Gengraf Neoral
Type of Drug  Immunosuppressant.
Restasis Ophthalmic Emulsion Sandimmune
Prescribed For
Kidney, heart, or liver transplantation; also used for bone-marrow, heart-lung, and pancreas transplants; also prescribed for patchy hair loss, rheumatoid arthritis, aplastic anemia, atopic dermatitis, Beh~et’s disease, cirrhosis of the liver, ulcerative colitis, dermatomyositis, eye symptoms of Graves’ disease, insulin-dependent diabetes, kidney inflammation, multiple sclerosis (MS), severe psoriasis and psoriasis-related arthritis, myasthenia gravis, pemphigus, sarcoidosis of the lung, and pyoderma gangrenosum. Cyclosporine eye emulsion is prescribed for dry eyes.
General Information
Cyclosporine is used to prevent rejection of transplanted organs. It works by blocking the activity of T-cells, which protect the body against invading microorganisms or foreign substances. Cyclosporine also prevents the production of a substance known as interieukin-11 that activates T-cells. In 1995, a new form of Cyclosporine called Neoral, a microemulsion, was introduced by its manufacturer. This form is as safe and effective as the original product but is better absorbed into the bloodstream and requires less medication to achieve the same effect. Cyclosporine eye emulsion treats dry eye caUV ,d by inflammation of the cornea and tissue kWA1 Covers the white part of the eye. It reduces inflammation and allows tears to form and flow.
Cautions and Warnings
Cyclosporine should be prescribed only by doctors experienced in immunosuppressive therapy and the care of organ-transplant patients. Sandimmune is always used with corticosteroid drugs like prednisone. Neoral and Gengraf have been used with a corticosteroid and azathioprine, an immune suppressant. When combined with other immune suppressants, cyclosporine must be used with great care because oversuppression of the immune system may lead to lymphoma or extreme susceptibility to infection.
Sandimmune, the original oral form of cyclosporine, is poorly absorbed into the bloodstream; it must be taken in a dosage that is 3 times greater than the injectable dosage. People taking this drug by mouth for a long period of time should have their blood checked for cyclosporine levels so that the dosage may be adjusted if necessary. Since more of both Gengraf and Neoral is absorbed into the blood you will probably need less of it. Do not substitute Neoral or Gengraf for Sandimmune; they are not equivalent to each other.
cyclosporine causes kidney toxicosis (kidney poisoning)—different from transplant rejection—in 25-35% of people taking it to prevent organ rejection. Mild symptoms usually start after about 2 or 3 months of treatment. Reducing drug dosage may control this effect. In one study, clonidine skin patches used before and after surgery decreased toxic risks to the kidney.
Liver toxicosis is seen in about 5% of transplant patients taking cyclosporine. It usually appears in the first month and may be controlled by reducing dosage.
Convulsions may develop, especially in people also taking high dosages of corticosteroids. Other nervous system side effects are listed below (see “Possible Side Effects”).
In one study, cyclosporine increased cholesterol and other blood-fat levels. It is not known how this affects people who take the drug on a long-term basis.
There is conflicting information on how cyclosporine affects blood sugar. Kidney-transplant patients taking the drug have developed insulin-dependent diabetes, which is related to the dosage of cyclosporine and reverses itself when you stop taking the drug. On the other hand, cyclosporine preserves the function of insuli(Nproducing cells in the pancreas and has allowed many insulin-dependent diabetics t0 11ve Without taking insulin.
UVb vaccines should not be given to people taking cyclosporine.
Do not use cyclosporine eye drops if you have an eye infection.
Small amounts of cyclosporine eye emulsion may be absorbed
into the bloodstream, but the risk of body-wide side effects is small.
Possible Side Effects
V Most common: Cyclosporine is known to be toxic to the kidneys. Your doctor will carefully monitor your kidney function while you are taking it. Other side effects are high blood pressure, increased hair growth, infection, and enlargement of the gums. Lymphoma may develop in people whose immune systems are excessively suppressed.
V Less common: tremors, cramps, acne, brittle hair or fingernails, convulsions, headache, confusion, diarrhea, nausea or vomiting, tingling in the hands or feet, facial flushing, reduced white-blood-cell and platelet counts, sinus inflammation, swollen and painful male breasts, drug allergy (symptoms include rash, itching, hives, and breathing difficulties), conjunctivitis (pinkeye), fluid retention and swelling, ringing or buzzing in the ears, hearing loss, high blood sugar, and muscle pain.
♦    Rare: blood in the urine, heart attack, itching, anxiety. depression, lethargy, weakness, mouth sores, difficulty swallowing, intestinal bleeding, constipation, pancreas inflammation, night sweats, chest pain, joint pain, visual disturbances, and weight loss. Contact your doctor if you experience any side effect not listed above.
Cyclosporine Eye Drops
♦    Most common: burning sensation.
✓    Less common: red-eye, discharge from the eye, overflow of tears, eye pain, a feeling of something in the eye, itching, stinging, and visual disturbances, usually blurring.
Drug Interactions
•    Cyclosporine should be used carefully with other kidney-toxic drugs including nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen, ac\d s0indac; ciprofloxacin; gentamicinjQtswnydin; vancomycin; trimethoprimsUM,M1~0oxazole; melphalan; amphotericin B; ketoconazole; azapropazon; colchicine; diclofenac; cimetidine; ranitidine; and tacrolimus.
•    Drugs that may increase blood levels of cyclosporine include contraceptive drugs; amiodarone; diltiazem; nicardipine; verapamil; fluconazole; itraconazole; ketoconazole; azithromycin; clarithromycin; erythromycin; quinapristin and dalfopristin; methylprednisolone—this combination also causes convulsions; allopurinol; bromocriptine; colchicine; imatinb-, danazol; and metoclopramide. With ketoconazole, your doctor may use this drug interaction to reduce your cyclosporine
dosage.
•    Drugs that decrease cyclosporine levels and may lead to organ rejection include octreotide, orlistat, sulfinpyrazone, ticlopidine, terbinafine, nafcillin, rifampin, carbamazepine, phenobarbital, phenytoin, and St. John’s wort. Rifabutin may also decrease concentrations of cyclosporine and should be used with caution.
•    Cyclosporine interferes with the body’s ability to clear digoxin, prednisolone, and statin drugs. People taking any of these drugs who start on cyclosporine must have their drug dosage reduced.
•    Combining cyclosporine and nifedipine may lead to gum overgrowth.
•    Cyclosporine increases blood potassium. Excessive blood-potassium levels may be reached if cyclosporine is taken with enalapril, lisinopril, a potassium-sparing diuretic such as spironolactone, salt substitutes, potassium supplements, or high potassium—low sodium—food.
•    Psoriasis patients using other immunosuppressant drugs or receiving radiation therapy should not take cyclosporine due to the danger of infection.
•    Cyclosporine prevents the normal body response to live vaccines. People taking cyclosporine should be vaccinated only after specific discussions with their doctors. You must wait for a period of several months to several years after stopping the medication before vaccination may be considered again.
Food Interactions
Cyclosporine may be taken with fMd 1111 upsets your stomach. For optimal QftlaWr~T)ess, avoid eating a fatty meal within half an hour of taking Neoral.
You may mix Neoral in a glass—not a paper or plastic cup—with room-temperature orange or apple juice or chocolate milk to make it taste better. Do not drink grapefruit juice because it speeds the breakdown of cyclosporine. Drink immediately after mixing, then put more juice or chocolate milk in the glass and drink it to be sure that the entire dose has been taken. Neoral should not be taken with unflavored milk because it may be unpalatable.
Usual Dose
In general, the usual dosage of Neoral is lower than Sandimmune, but dosage must be individualized for you by your doctor. Do not substitute one brand for the other.
Sandimmune
Adult: The usual oral dosage of cyclosporine is 6-8 mg per lb, of body weight a day. The first dose, typically 15 mg per lb., is given 4-12 hours before the transplant operation or immediately after surgery. This dosage is slowly reduced to 11-22 mg per lb. of body weight.
Child: Similar dosages are usually prescribed, but because children tend to release the drug from their bodies faster than adults, larger and more frequent doses may be needed.
Neoral and Gengraf
Adult: In newly transplanted patients, the usual oral dosage of Neoral is 3-4 mg per lb. of body weight a day divided into 2 doses. The initial oral dose of Gengraf is the same as for Sandimmune. The first dose is given 4-12 hours before the transplant operation or immediately after surgery. This dosage is continued after the operation for 1-2 weeks and then slowly reduced to maintain a target amount of cyclosporine in the body. Dosage may vary according to the organ transplanted.
In people being treated for rheumatoid arthritis or psoriasis, the initial dose of Neoral and Gengraf is 1.13 mg per lb. of body weight increased gradually to a maximum of 1.8 mg per lb. of body weight.
Child: Similar dosages are usually prescribed but, because children tend to release the drug from their bodies faster than adults, larger and more frequent doses may be needed.
cyclosporine Eye Emulsion
One drop in the affected eye(s) every Q hours. Before using, rotate and turn the vial Over a few times until you have a uniform, lft8, opaque fluid inside. If you use artificial tears, allow 15 minutes between products. Discard the open vial immediately after use.
Overdosage
Overdose victims may be expected to develop side effects and symptoms of extreme immunosuppression. Induce vomiting with ipecac syrup—available at any pharmacy—which is recommended up to 2 hours after the overdose was taken. Call your doctor or local poison control center before inducing vomiting. If you must go to a hospital emergency room, ALWAYS bring the prescription
bottle or container.
Special Information
Call your doctor at the first sign of fever; sore throat; tiredness’, weakness’, nervousness; unusual bleeding or bruising; tender or swollen gums; convulsions; irregular heartbeat; confusion; numbness or tingling of your hands, feet, or lips; breathing difficulties; severe stomach pain with nausea; or blood in the urine. Other side effects such as shaking or trembling of the hands, increased hair growth, acne, headache, leg cramps, nausea, or vomiting are less serious but should be brought to your doctor’s attention, particularly if they are bothersome or persistent.
Maintain good dental hygiene while taking cyclosporine and use extra care when brushing and flossing because the drug increases your risk of oral infection. cyclosporine may also cause swollen gums. See your dentist regularly.
Continue taking your medication as long as your doctor prescribes it. Do not stop taking it without your doctor’s knowledge. If you cannot take one of the oral forms, cyclosporine can be given by injection.
Do not keep either brand of the oral liquid in the refrigerator. After the bottle is opened, use the medication within 2 months. At temperatures below 68°F, Neoral can form a gel and a light sediment can form in Sandimmune. These do not affect the potency of either product. They can still be used and are effective.
If you forget a dose, take it as soon as you remember if it is within 12 hours of your regular dose. If not, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
For cyclosporine eye emulsion, each small plastic container is meant to be used once and then thrown away along with any remaining medication. Do not allow the tip of the disposable vial to touch 0Z QyE or any surface, as this may contaminate the emulsion.
Patients with decreased tear production typically should not wear contact lenses. But those that do must remove them before using cyclosporine eye emulsion. Lenses may be reinserted 15 minutes after using the medicine.
Special Populations
Pregnancy/Breast-feeding: In animal studies cyclosporine damages the fetus. Though a small number of pregnant women have taken cyclosporine without major problems, it is recommended that pregnant women avoid cyclosporine. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
cyclosporine passes into breast milk. Nursing mothers who must take cyclosporine should use infant formula.
Seniors: Due to decreased kidney function, seniors are more susceptible to kidney toxicosis.

Generic Name
Darunavir (dah-ROON-uh-vere)
Brand Name Prezista
Type of Drug  Protease inhibitor.
Prescribed For
Advanced human immunodeficiency virus (HIV) infection that has not responded to other protease inhibitors.
General Information
Part of the multidrug “cocktail” responsible for important gains in the fight against acquired immunodefiency syndrome (AIDS), darunavir is a member of a group of anti-HIV drugs called protease inhibitors. These drugs work at the end of the HIV reproduction process, whet) proteins are “cut” into strands of exactly tht VbYrect size to duplicate HIV. An enzyme known as protease cuts the protein. Protease inhibitors prevent the mature HIV virus from being formed by inhibiting this cutting process. Proteins that are cut to the wrong length or that remain uncut are inactive.
Darunavir must be taken with a low dose of ritonavir, another protease inhibitor, to extend the action of darunavir in the body.
Without ritonavii, darunavir would be eliminated too rapidly to be effective. Darunavir must also be accompanied by at least 2 other AIDS antivirals. Protease inhibitors revolutionized HIV treatment because, when taken in combination, they reduce the amount of HIV virus in the bloodstream to levels that are often undetectable by current methods—CD4 (immune system) cell counts and viral load (amount of virus in the blood) measurements. Multiple-drug therapy has transformed HIV from a fatal disease to a manageable chronic illness.
Cautions and Warnings
Do not take darunavir if you are allergic or sensitive to any of its ingredients, to sulfa drugs, or to ritonavir.
Darunavir can cause a severe or life-threatening rash.
If a serious toxic reaction occurs while taking darunavir, you should stop the drug until your doctor can determine the cause or until the reaction resolves itself. Then treatment can be resumed.
This drug is primarly broken down in the liver. Use caution if you have moderate to severe liver disease.
Darunavir may raise your blood sugar, worsen your diabetes, or bring out latent diabetes. People with diabetes who take darunavir may need the dosage of their antidiabetes medication adjusted.
People with hemophilia may be more likely to bleed while taking a protease inhibitor.
The HIV virus may become resistant to darunavir or other protease inhibitors. For this reason it is essential that you take darunavir exactly according to your doctor’s directions.
Protease inhibitors can cause body fat redistribution, including increased fat deposits in the upper back and neck, breast and around the back, chest, and stomach. Fat may be lost from the legs, arms, and face. Some people with HIV and a history of an opportunistic infection may develop signs and symptoms of the infection soon after anti-HIV treatment is started. This is called immune reconstitution syndrome.
Darunavir is involved in many drug interactions. Check with your doctor before adding angt ng new to your treatment program.
Possible Side Effects
V Most common: diarrhea, nausea, headache, and common cold symptoms.
of constipation.
Drug Interactions
•    Do not take any of the following medicines with darunavir + ritonavir: astemizole, terfenidine, ergot-based drugs for migraine headache, cisapride, pimozide, midazolam, or triazolam. Mixing these drugs with darunavir + ritonavir can result in very high blood levels and serious side effects.
•    Carbamazepine, phenobarbital, phenytoin, rifampin, and St. John’s wort can substantially reduce blood levels of darunavir. Do not mix these medicines.
•    Lopinavir + ritonavir and saquinavir can significantly reduce blood levels of darunavir. Darunavir significantly increases blood levels of lopinavir + ritonavir. Do not mix these drugs.
•    Mixing darunavir with indinavir can increase blood levels of both drugs.
•    Darunavir + ritonavir does not appear to affect blood levels of atazanavir, nor does atazanavir appear to affect blood levels of darunavir + ritonavir. It may be possible to combine these two protease inhibitors.
•    Taking darunavir with tenofovir can increase blood levels of both drugs. These drugs can be combined with no dose adjustments, though it is necessary to watch carefully for kidney damage related to tenofovir.
•    Darunavir can increase blood levels of efavirenz and efavirenz reduces darunavir levels. These medicines should be mixed with caution.
•    Darunavir increases nevirapine blood levels but the raMUNnation can be taken with no dose a-Syoslment.

adjustment is necessary in people with normal kidney function.    the Darunavir + ritonavir may reduce vonconazole levels in t e
blood. Do not mix these medicines.
•    Darunavir + ritonavir can increase rifabutin levels in the blood-
stream. Rifabutin can also reduce darunavir levels in the
bloodstream. If rifabutin is mixed with darunavir + ritonavir,
the rifabutin dose should be 150 mg every other day.
•    Caution should be exercised when combining darunavir + ritonavir with calcium channel blockers such as felodipine, nifedipine, and nicardipine.
•    Darunavir increases blood levels of the heart antiarrhythmic drugs bepridil, lidocaine, and quinidine. These drugs should be used together with caution and only in situations where blood levels of the heart drugs can be monitored regularly.
•    Darunavir + ritonavir can reduce blood levels of warfarin. It is necessary to monitor warfarin levels while taking this combination.
•    Darunavir + ritonavir can raise blood levels of the tricyclic antidepressant desipramine and the tetracyclic antidepressant trazodone. Dosage reduction is recommended.
•    Darunavir + ritonavir may reduce blood levels of the SSRI antidepressants sertraline and paroxetine. SSRI doses may have to be increased to account for this effect.
•    Darunavir + ritonavir can drastically increase the blood levels of some statin-type cholesterol-lowering drugs, substantially increasing the risk of statin side effects. Simvastatin, pravastatin, and lovastatin should not be mixed with darunavir + ritonavir. It is also possible to take darunavir + ritonavir with atorvastatin, although it can increase the level of atorvastatin in the bloodstream. If atorvastatin is prescribed, it is best to begin with 10 mg a day and slowly increase the dose as necessary. Little is known about how darunavir + ritonavir affects rosuvastatin. The safest statin to take with darunavir + ritonavir is fluvastak”.
•    Darunavir + ritonaxk Can increase blood levels of inhaled MT lCosteroids dexamethasone and fluticasone, the anti-rejection drugs cyclosporine, tacrolimus, and sirolimus. The corticosteroids reduce darunavir blood levels, interfering with its effectiveness.
•    Darunavir + ritonavir can reduce methadone levels in the bloodstream. Methadone dose adjustment may be needed.
•    Darunavir + ritonavir reduces the effectiveness of some contraceptive drugs by decreasing the amount of the hormones ethinyl estradiol and norethindrone in the bloodstream. Women mixing these medicines should use additional contraceptive measures (e.g., condoms).
•    Protease inhibitors may drastically increase blood levels of erectile dysfunction drugs sildenafil, vardenafil, and tadalafil, increasing the risk of side effects including low blood pressure, visual changes, and persistent, painful erection.
•    Dexamethasone may reduce blood levels of darunavir.
Food Interactions
Take darunavir with food. The amount of darunavir absorbed into the blood is vastly reduced when it is taken on an empty stomach, thus negating its antiviral effects.
Usual Dose
Adult: 600 mg (2 300-mg tablets) with 1 00 mg ritonavir twice a day. Do not chew these tablets.
Child: not recommended.
Overdosage
Little is known about the effects of darunavir overdose, but 3200 mg of darunavir has been given to study volunteers with no adverse effects. Call your local poison center or hospital emergency room for more information. If you take the victim to a hospital emergency room, ALWAYS bring the prescription bottle or container.

Generic Name
Clozapine (KLOE-zuh-pene) 03
Brand Names
Clozaril    FazaClo Orally Disintegrating Tablets
Type of Drug  Antipsychotic.
Prescribed For  Severe schizophrenia.
General Information
Clozapine is a unique antipsychotic that has the capacity to treat people who do not respond to or cannot tolerate other drugs. It works by a mechanism that differs from those of other antipsychotic drugs.
A very small number of people who take clozapine develop a rapid drop in their white-blood-cell count, known as agranulocytosis. This effect usually reverses itself when the drug is stopped, but the drug must be stopped as soon as it is discovered. An unusually large number of people who have developed clozapine algllaTwlocytosis in the United States are of Eastern European Jewish descent, but the association is not very strong. Most cases of agranulocytosis occur between week 4 and week 10 of treatment. It is essential that blood samples be taken approximately every week and for 4 weeks after the drug is stopped to watch for this effect. Because of the risk of agranulocytosis, clozapine should not be tried until at least 2 other antipsychotic medicines have failed.
Some people taking antipsychotic drugs develop tardive dyskinesia, a potentially irreversible condition marked by uncontrollable movements. Tardive dyskinesia has not been seen in patients taking clozapine, a major advantage of this drug over other antipsychotic medicines. However, there is still a risk that this set of symptoms could occur with clozapine.
Cautions and Warnings
Do not take clozapine if you are allergic or sensitive to any of its ingredients.
Women, seniors, people with serious illnesses, those who are emaciated. those with a history of diseases affecting the white blood cells, or those who are taking other medication that could affect white blood cells may be more susceptible to clozapine agranulocytosis.
Clozapine has been associated with increased mortality in seniors with dementia or Alzheimer’s disease. The specific causes of death related to clozapine and other atypical antipsychotic drugs were either due to a heart-related event or infection, mostly pneumonia. Clozapine should not be taken by those with dementia-related psychosis.
About 5% of people taking the drug experience a seizure in the first year of treatment. Seizure is most likely to occur at higher drug doses.
People with heart disease should be carefully monitored while on clozapine because of possible cardiac risks.
Clozapine may cause low blood pressure, especially at the beginning of therapy.
Clozapine has been associated with obesity, high cholesterol, high blood sugar, and diabetes. Diabetics and pre-diabetics (people with elevated blood sugar and a family history of diabetes) should be carefully monitored.
A serious set of side effects, known as neuroleptic malignant syndrome (NMS), includes a high lever and has been associated With clozapine when it is used together with lithium or other drugs. The symptoms that constitute NMS include muscle rigidity, mental changes, irregular pulse or blood pressure, increased sweating, and abnormal heart rhythm. NMS is potentially fatal and requires immediate medical attention.
Use this drug with caution if you have glaucoma, prostate
problems, or liver or kidney disease.
clozapine may interfere with mental or physical abilities because of the sedation it usually causes during the first few weeks
of treatment.
Possible Side Effects
✓    Most common: rapid heartbeat, low blood pressure, dizziness, fainting, drowsiness or sedation, salivation, and constipation.
✓    Less common: headache, tremor, sleep disturbance, restlessness, slow muscle motions, absence of movement, agitation, convulsions, rigidity, restlessness, confusion, sweating, dry mouth, visual disturbances, high blood pressure, nausea, vomiting, heartburn or abdominal discomfort, fever, and weight gain.
♦    Rare: agranulocytosis (symptoms include fever with or without chills, sore throat, and sores or white spots on the lips or mouth), tardive dyskinesia (symptoms include lip smacking or puckering, puffing of the cheeks, rapid or wormlike tongue movement, uncontrolled chewing motions, and uncontrolled arm and leg movements), and NMS (see “Cautions and Warnings”). Other rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Clozapine’s anticholinergic effects—blurred vision, dry mouth, and confusion—may be enhanced by interaction with other anticholinergics, such as tricyclic antidepressants like amitriptyline.
•    Drugs that reduce blood pressure may enhance the bloodpressure-lowering effects of clozapine.
•    Alcohol and other nervous system depressants, including benzQUIQOmrn and other antianxiety drugs, may enhance clozapine’s sedative action. At least 1 person has died as a result of combining diazepam and clozapine.
•    Combination contraceptive drugs may increase blood levels of clozapine leading to toxic side effects. Women starting on a combination contraceptive may need to have their clozapine dose adjusted.
•    Clozapine should not be used with ritonavir.
•    Cimetidine, caffeine, citalopram, ciprofloxacin, erythromycin, and ketoconazole may increase blood levels of clozapine resulting in increased side effects. Caution should be used with combining clozapine with paroxetine, fluvoxamine, or sertraline as similar reactions may occur, although these interactions are less well-defined.
•    Clozapine may increase blood levels of digoxin, warfarin, heparin, and phenytoin.
•    Use of clozapine with phenytoin, carbamazapine, and rifampin may cause decreases in blood levels of clozapine, reducing its effectiveness.
•    The combination of lithium and clozapine may cause seizures, confusion, and NMS (see “Cautions and Warnings”).
•    Cigarette smoking may alter clozapine dosage requirements.
•    Combining selective serotonin receptor inhibitors (SSRls) with clozapine may require a lower clozapine dosage.
Food Interactions None known.

Symptoms of overdose are delirium, drowsiness, changes in heart rhythm, unusual excitement, nervousness, restlessness, hallucinations, excessive salivation, dizziness or fainting, slow or irregular breathing, and coma, Overdose victims must be taken to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special Information
Clozapine may cause a fever during the first few weeks of treatment. Generally, the fever is not important, but it may occasionally be necessary to stop treatment due to a persistent fever.
Regular blood tests are necessary to monitor blood composition for any changes that might be caused by clozapine.
Call your doctor at once if you develop lethargy or weakness, a flu-like infection, sore throat, feelings of ill health, fever, sweating, muscle rigidity, mental changes, irregular pulse or blood pressure, mouth ulcers, or dry mouth that lasts for more than 2 weeks.
Dry mouth, a common side effect of clozapine, may be countered by using gum, candy, ice, or a saliva substitute such as Orex or Moi-Stir.
Do not stop taking clozapine without your doctor’s knowledge and approval, because a gradual dosage reduction may be necessary to prevent side effects.
Avoid alcohol or any other nervous system depressants while taking clozapine.
Some of the side effects of clozapine    drowsiness, blurred vision, and seizures—may interfere with the performance of complex tasks like driving or operating hazardous equipment.
While taking clozapine, rapidly rising from a sitting or lying position may cause you to become dizzy or faint.
If you take clozapine twice a day and forget a dose, take it as soon as you remember. If it is almost time for your next dose, take 1 dose as soon as you remember and another in 5 or 6 hours, then go back to your regular schedule. If you take clozapine 3 times a day and forget a dose, take it as soon as you remember. If it is almost time for your next dose, take 1 dose as soon as you remember and another in 3 or 4 hours, then go back to your regular schedule. Never take a double dose.
Orally disintegrating tablets should be left in the unopened blister until time of use. They should not be pushed through the foil. Just prior to use, peel the foil from the blister and gently remove the orally disintegrating tablet. Immediately place the tablet in the mouth, allow it to disintegrate and then swallow with saliva. No water is needed.
Special Populations
Pregnancy/Breast-feeding: This drug Should be used during PM Only if your doctor determines that it is absolutely necessary.
clozapine may pass into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors may be more sensitive to the side effects of clozapine, such as dizziness on rapidly rising from a sitting or lying po-sition, confusion, and excitability. Older men are also more likely to have prostate problems, a reason to be cautious with clozapine. Seniors with psychosis due to dementia who take clozapine are more likely to die from heart disorders and infections than those not taking it.

Prescribed For
Mild to severe pain, breakthrough cancer pain, and cough. Long-acting narcotics are meant only for people with chronic pain. Also prescribed for pain and anxiety in pediatric burn patients.
General Information
Codeine relieves pain and suppresses cough. The pain-relieving effect of 30-60 mg of codeine is equal to approximately 650 mg, or 2 tablets, of aspirin. Codeine may be less effective than aspirin for pain associated with inflammation because aspirin reduces inflammation and codeine does not. Codeine suppresses the cough reflex but does not cure the underlying cause of the cough. Other narcotic cough suppressants are stronger pain relievers, but codeine remains the best cough medication available.
Morphine sulfate is a pure narcotic that has been in use for many years. In addition to pain relief, morphine’s effects include drowsiness, mood changes, breathing difficulty, slowed movement of the gastrointestinal tract, nausea, vomiting, and changes in the endocrine and autonomic nervous systems. Morphine sulfate liquid, immediate-release tablets, and suppositories must be taken several times a day. The medication they contain is released immediately for absorption into the bloodstream. Extended- and controlled-release morphine products are designed to release some of the narcotic right away and the rest over a 24-hour period, allowing for less-frequent dosage.
Fentanyl is a potent pain reliever that can be substituted for other narcotic drugs. The patch form, which must be replaced about every 3 days, delivers fentanyl to the bloodstream at a steady rate. The lozenge has a shorter length of action than any other narcotic pain reliever, which makes it useful when given to children before surgery because it provides doctors with the flexibility to obtain maximum benefit with minimal side effects. The lozenge on a stick is used for breakthrough cancer pain as a booster for people already taking narcotic pain relievers. These forms should only be used under controlled circumstances because of the risk of side effects or overdose. Low dosages of fentanyl relieve pain—larger amounts cause loss of consciousness and breathing difficulties.
Oxycodone is a narcotic used to control moderate to severe pain. Most people take it together with aspirin (Percodan) or acetaminophen (Percocet), but it can be used by itself. This is a potent pain reliever that carries a risk (31 addiction with continued use.
Cautions and Warnings
Do not take narcotics if you are allergic or sensitive to any of their ingredients.
Long-term use of narcotics may cause drug dependence or addiction.
Use narcotics with extreme caution if you suffer from asthma or other breathing problems.
Narcotics may make it difficult to monitor the progress of people who have suffered head injuries and acute abdominal conditions.
Actiq contains fentanyl in an amount that can be fatal to children. Keep used and unused lozenges and lozenges on a stick out of reach of children.
Possible Side Effects
♦    Most common: lightheadedness, dizziness, sleepiness, nausea, vomiting, appetite loss, and sweating. If these occur, ask your doctor about lowering your dosage. Most of these side effects disappear if you lie down.
♦    Less common: euphoria (feeling “high”), headache, agitation, uncoordinated muscle movement, minor hallucinations, disorientation and visual disturbances, dry mouth. constipation, flushing of the face, rapid heartbeat, palpitations, faintness, urinary difficulties or hesitancy, reduced sex drive or impotence, itching, rash, anemia, lowered or raised blood sugar, and yellowing of the skin or whites of the eyes. Narcotic analgesics may aggravate convulsions in those who have had them.
More serious side effects of codeine are shallow breathing or breathing difficulties.
Drug Interactions
•    Avoid combining narcotics with alcohol, sleeping medications, sedatives, other depressant drugs, or non-prescription drugs that have alcohol as an ingredient. Alcohol speeds the release of morphine from Avinza. The mixture can result in a deadly narcotic overdose.
•    Narcotic analgesics should not be used at the same time as monoamine oxidase inhibitor antidepressants. Separate usage by at least 14 days.
•    Combining a narcotic pain reliever with an anticholinergic medication may result in severe constipation.
•    Combining a narcotic pain reliever with any other medication that lowers blood pressure can lead to excessive blood-pressure lowering. Avoid this combination.
•    Combining cimetidine with a narcotic pain reliever may cause confusion, disorientation, breathing difficulties, and seizure.
•    Reserpine, rifampin, and remifentanil may decrease the pain-relieving effects of morphine.
•    Fentanyl should be used with caution with azole antifungals (e.g. ketoconazole).
Food Interactions
Codeine may be taken with food to reduce upset stomach. Morphine capsules and the fentanyl patch may be used without regard to food.
Usual Dose

Overdosage
Symptoms include breathing difficulties or slowing of respiration, extreme tiredness progressing to stupor and then coma, pinpointed pupils, no response to pain stimulation, cold and clammy skin, slowing of heartbeat, lowering of blood pressure, convulsions, and cardiac arrest. The victim should be taken to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special Information
Codeine is a respiratory depressant and affects the central nervous system (CNS), producing sleepiness, tiredness, or inability to concentrate. Be careful when driving or doing any task that requires concentration. Avoid alcohol.
Call your doctor if you develop breathing difficulties, constipation, dry mouth, or any bothersome or persistent side effect.
Apply the fentanyl patch only to non-irritated skin on a flat surface of the upper body. Hair at the application site should be clipped or cut, not shaved, before applying the patch. Do not use oils, soaps, lotions, alcohol, or anything else that might irritate the skin before applying the patch.
If you are taking a controlled-release narcotic product, do not crush, chew, or break the tablet or lozenge. Rapid release may result in a potentially fatal dose of the drug.
If you forget a dose of codeine, take it as soon as you remember. If it is almost time for your next dose, skip the one you forgot and continue with your regular schedule. Never take a double dose.
Special Populations
Pregnancy/Breast-feeding: Narcotics pass into the fetal circulation. Excessive use of them during pregnancy may cause drug dependence in newborns. Narcotics may also cause breathing difficulties in infants during delivery. Animal studies show that codeine may cause fetal harm. If given to a pregnant woman before cesarean section, fentanyl may cause drowsiness in newborns. When either of these drugs is considered crucial by your doctor, its potemt(a1 bel)elft must be carefully weighed against its risks.
Narcotics pass into breast milk. Nursing mothers who must take codeine should use infant formula.
Seniors: Seniors are more likely to be sensitive to side effects and should be treated with the smallest effective dosage.

Type of Drug
Alpha receptor stimulant.
Prescribed For
High blood pressure, including hypertensive emergency (diastolic blood pressure over 120); also used for excess sweating, childhood growth delay, attention-deficit hyperactivity disorder (ADHD), Tourette’s syndrome, restless leg syndrome, schizophrenic psychosis, migraine, ulcerative colitis, painful or difficult menstruation, hot flashes related to menopause, diagnosis of pheochromocytoma (adrenal-gland tumor), kidney poisoning associated with cyclosporine, diabetic diarrhea, smoking cessation, methadone and opiate detoxification, withdrawal from alcohol and benzodiazepines such as Valium, nerve pain following herpes attack, and allergic reactions in the presence of asthma triggered by external sources.
General Information
Clonidine stimulates nerve endings in the brain called alphaadrenergic receptors. It reduces blood pressure by dilating (widening) blood vessels. Clonidine works quickly, decreasing blood pressure within 1 hour. The other uses of clonidine relate to its stimulation of alpha receptors in the body.
Cautions and Warnings
Do not take clonidine if you are allergic or sensitive to any of its ingredients.
People who have had a stroke or recent heart attack or who have cardiac insufficiency or chronic kidney failure should avoid taking clonidine.
Some people develop a tolerance of their clonidine dosage. If this happens, your blood pressure may increase and your doctor may prescribe a higher dose.
Never stop taking clonidine without your doctor’s knowledge. If you abruptly stop taking clonidine, you may experience an unusual increase in blood pressure accompanied by agitation, headache, nervousness, and severe reactions, possibly death. Restarting clonidine therapy or taking another antihypertensive can reverse these effects.

Rashes of the face and tongue have also occurred but cannot be specifically tied to transdermal clonidine.
Drug Interactions
•    Combining clonidine and a beta-adrenergic blocker may increase the severity of a drug-withdrawal reaction and rebound high MW pressure. This reaction may be very serious.
•    Combining verapamil and clonidine may lead to very low blood pressure and atrioventricular (AV) block (abnormality in heartbeat patterns). This reaction may be very serious.
O    Avoid alcohol, barbiturates, and sedatives because they increase the depressive effects of clonidine.
•    Tricyclic and other antidepressants, appetite suppressants, estrogens, stimulants, indomethacin and other nonsteroidal anti-inflammatory drugs (NSAIDs), and prazosin may counteract the effects of clonidine.
•    clonidine may reduce the therapeutic effects of levadopa +
carbidopa.
Food Interactions
The tablets are best taken on an empty stomach but may be taken with food if they upset your stomach.
Usual Dose
Tablets
Adult: high blood pressure-100 mcg twice a day to start; may be raised by 100 mcg a day until maximum control is achieved. Take no more than 2400 mcg a day. Other uses-100-goo mcg a day, or up to 0.8 mcg per lb. of body weight in divided doses. Seniors should start with a lower dose and increase more slowly.
Child: 50-400 mcg orally twice a day.
Transdermal Patch
Adult: 100 mcg delivered daily from a patch applied once every 7 days. Up to two 300-mcg patches may be needed to control blood pressure. Transdermal dosage exceeding 600 mcg a day has not been shown to increase effectiveness.

Victims should be taken to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special Information
Gk’3t1161)e causes drowsiness in about 1/3 of people who take it. Be extremely careful while driving or performing any task that requires concentration. This effect is prominent during the first few weeks of clonidine therapy and then tends to decrease.
Do not take over-the-counter cough and cold medications unless directed by your doctor.
Call your doctor it you become depressed or have vivid dreams or nightmares while taking clonidine, or if you develop swelling in your feet or legs, paleness or coldness in your fingertips or toes, or any persistent or bothersome side effect.
Apply the transdermal patch to a hairless area of skin such as the upper arm or torso. Use a different skin site each time. If the patch becomes loose, apply the supplied adhesive directly over it. If the patch falls off before 7 days are up, apply a new one. Do not remove the patch while bathing.
If you forget a dose of oral clonidine, take it as soon as possible and then go back to your regular schedule. If you miss 2 or more consecutive doses, consult your doctor; missed doses may cause blood pressure increases and severe adverse effects. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Clonidine passes into the fetal bloodstream. Animal studies show that clonidine may damage the fetus in doses as low as 1/3 the maximum dose. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
Clonidine passes into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors are more susceptible to the effects of this drug and should begin with lower doses.

Generic Name
Clopidogrel (kloe-PID-oe-grel) nQ
Brand Name  Plavix
Type lul Drug Antiplatelet.
Prescribed For
Heart attack and stroke prevention; also used for blood thinning after placement of a vascular stent.
General Information
Artery-clogging blood clots are often the cause of heart attacks and strokes. clopidogrel reduces the risk of both by helping prevent blood-clot formation. This drug thins the blood by making platelets—the cells that aggregate to form clots—less “sticky.” It starts working in as little as 2 hours after taking a single tablet. The drug’s blood-thinning effect lasts until inactivated platelets are replaced by the body. Studies suggest that clopidogrel is more effective than aspirin in preventing heart attack and stroke in people at risk. People taking clopidogrel after scent surgery usually take it for a relatively short period. Those taking it to prevent a heart attack or stroke must take it for life.
Cautions and Warnings
Do not take clopidogrel if you are allergic or sensitive to any of its ingredients or to ticlopidine, a related antiplatelet. These drugs can rarely cause a rapid drop in white-blood-cell count.
People with bleeding ulcers, brain hemorrhages, or other bleeding problems should use clopidogrel with caution.
Thrombotic thrombocytopenic purpura (TTP) is a rare but serious complication of clopidogrel, sometimes reported after less than 2 weeks of treatment. See your doctor right away if you develop a sudden fever, unusual bruising, nosebleeds, bleeding gums, or any other unusual symptoms. TTP reduces your platelet count, interfering with blood clotting, and affects white-blood-cell count.
People with liver problems should use clopidogrel with caution.
Possible Side Effects
✓    Most common: rash and other skin problems.
✓    Common: chest pain, accidents, flu-like symptoms, pain, headache, dizziness, abdominal pain, upset stomach, joint pain, back pain, black-and-blue marks, and respiratory infection.
✓    Less common: tiredness, Swollen arms or legs, high blood pressure, diarrhea, nausea, bleeding, nosebleeds, breathing difficulties, runny nose, coughing, bronchitis, high blood cholesterol, urinary infection, and depression.
✓    Rare: bleeding in the brain and stomach ulcer. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Clopidogrel may interfere with the body’s ability to break down fluvastatin, nonsteroidal anti-inflammatory drugs (NSAIDs), phenytoin, tamoxifen, tolbutamide, torsamide, and
warfann.
•    Combining clopidogrel and NSAIDs may increase blood loss and bleeding in the stomach and intestines.
•    Do not combine clopidogrel and other antiplatelet drugs or
the anticoagulant (blood thinner) warfarin unless you are
under your doctor’s direct supervision. This interaction may
prevent normal blood clotting and lead to severe bleeding
problems.
Food Interactions
Clopidogrel may be taken without regard to food or meals.
Usual Dose
Adult: 75 mg a day.
Overdosage
Little is known about the effects of clopidogrel overdose aside from reduced blood clotting. Overdose victims should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Minor cuts may take longer to stop bleeding during treatment with clopidogrel. If you are having surgery, make sure your doctor knows you are taking clopidogrel. You may have to stop taking the drug I week before surgery.
If you forget a dose, take it as soon as you remember. If it is almost time for your next dose, skip the forgotten dose and continue with your regular schedule.
Special Populations
Pregnancy/Breast-feeding: The safety of using clopidogrel during pregnancy is not known. Other antiplatelet drugs, tike aspirin, are not used during pregnancy due to their possible effects on Mrjlher and fetus. When this drug is considered crucial by your doctor, its benefits must be carefully weighed against its risks.
Clopidogrel may pass into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors may take this drug without special precaution.

Generic Name
Clorazepate (klor-AZ-uh-pate) 99
Brand Names
Gen-Xene    Tranxene-SD
Tranxene    Tranxene T-Tab
Type of Drug
Benzodiazepine sedative.
Prescribed For
Anxiety, tension, fatigue, and agitation; symptoms of acute alcohol withdrawal; partial seizures; also prescribed for irritable bowel syndrome and panic attacks.
General Information
Clorazepate dipotassium is a benzodiazepine. Benzodiazepines directly affect the brain. They can relax you and make you more tranquil or sleepier, or they can slow nervous system transmissions in such a way as to act as an anticonvulsant. Many doctors prefer benzodiazepines to other drugs that can be used to similar effect because they tend to be safer, have fewer side effects, and usually work as well, if not better.
Cautions and Warnings
Do not take clorazepate if you are allergic or sensitive to any of its ingredients or to another benzodiazepine drug, including clonazepam.
Clorazepate can aggravate narrow-angle glaucoma, but you may take it if you have open-angle glaucoma and are receiving therapy for it.
Other conditions in which clorazepate should be avoided are: severe depression, severe lung disease, sleep apnea (intermittent cessation of breathing during sleep), liver disease, drunkenness, and kidney diseaap_, to inOn of these conditions, the qq)NSSvve effects of clorazepate may be enhanced or could be detrimental to your overall condition.
Clorazepate should not be taken by psychotic patients because it is not effective for them and can trigger unusual excitement, stimulation, and rage.
Clorazepate is not intended to be used for more than 3-4 months at a time. Your doctor should reassess your condition before continuing your prescription beyond that time.
Clorazepate may be addictive. It should be used with caution in people with a history of drug dependence.
Drug withdrawal may develop if you stop taking it after as few as 4 weeks of regular use but is more likely after longer use. It may start with anxiety and progress to tingling in the hands or feet, sensitivity to bright light, sleep disturbances, cramps, tremors, muscle tension or twitching, poor concentration, flu-like symptoms, fatigue, appetite loss, sweating, and changes in mental state. Your dosage should always be reduced gradually to prevent drug withdrawal symptoms.
Possible Side Effects
Weakness and confusion may occur, especially in seniors and in those who are more sickly.
✓    Most common: mild drowsiness during the first few days of therapy.
✓    Less common: confusion, depression, lethargy, disorientation, headache, inactivity, slurred speech, stupor, dizziness, tremors, constipation, dry mouth, nausea, inability to control urination, sexual difficulties, irregular menstrual cycle, changes in heart rhythm, low blood pressure, fluid retention, blurred or double vision, itching, rash, hiccups, nervousness, inability to fall asleep, and occasional liver and kidney dysfunction. If you have any of these symptoms, stop taking the medicine and contact your doctor immediately.
✓    Rare: Rare side effects can affect your heart, stomach and intestines, urinary tract, blood, muscles and joints. Contact your doctor if you experience any side effects not listed above.
Drug Interactions
•    Clorazepate is a central-nervous-system depressant. Don’t mix it with alcohol, other sedatives, narcotics, barbiturates, monoamine oxidase inhibitor and other antidepressants, and antihistamines. Taking Clorazepate with these drugs may result in excessive depression, tiredness, sleepiness, breathing difficulties, or related symptoms.
•    Smoking may reduce clorazepate’s effectiveness by in-
creasing the rate at which it is broken down by the body.
•    Clorazepate’s effects may be prolonged when it is mixed with cimetidine, contraceptive drugs, disulfiram, fluoxetine, isoniazid, ketoconazole, metoprolol, probenecid, propoxyphene, propranolol, rifampin, or valproic acid. Theophylline may reduce clorazepate’s sedative effects.
•    If you take antacids, separate them from your clorazepate dose by at least 1 hour to prevent them from interfering with the absorption of clorazepate into the bloodstream.
•    Clorazepate may increase blood levels of digoxin and the chances of digoxin toxicity.
•    The effect of levodopa + carbidopa may be decreased if it is taken together with clorazepate.
•    Combining clorazepate with phenytoin may increase phenytoin blood concentrations and the chances of phenytoin toxicity.
Food Interactions
Clorazepate is best taken on an empty stomach, but it may be taken with food if it upsets your stomach.
Usual Dose
Immediate-Release
Adult and Child (age 9 and over): 15-60 mg daily. The average dose is 30 mg in divided quantities, but dosage must be adjusted to individual response for maximum effect. Maximum recommended daily dose is 90 mg. For treatment of anxiety, clorazepate may be taken as a single dose at bedtime.
Child (under age 9): not recommended.
Sustained-Release
Adult: The sustained-release form of clorazepate may be given as a single dose, either 11.25 or 22.5 mg, once every 24 hours. Sustained-release tablets are not recommended for the initial dosage.
Child: not recommended.
Overdosage
Symptoms of overdose are confusion, sleepiness, poor coordination, lack of response to pain such as a pin prick, loss of reflexes, shallow breathing, low blood pressure, and coma. The victim should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Clorazepate can cause tiredness, drowsiness, inability to concentrate, or similar symptoms. Be careful if you are driving, operating machinery, or performing other activities that require concentration.
People taking clorazepate for more than 3 or 4 months at a time may develop drug withdrawal reactions if the medication is stopped suddenly (see “Cautions and Warnings”). Do not stop taking clorazepate or increase or decrease your dosage without first consulting your doctor.
If you forget a dose of clorazepate, take it as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Clorazepate may cause birth defects if taken during the first 3 months of pregnancy. Avoid this drug if you are or might be pregnant.
Clorazepate may pass into breast milk. Nursing mothers who must take clorazepate should use infant formula.
Seniors: Seniors, especially those with liver or kidney disease, are more sensitive to the effects of clorazepate and generally require smaller doses to achieve the same effect.

Generic Name
Carvedilol (car-VAY-dih-lol)
Brand Names
Coreg    Coreg CR
Type of Drug  Alpha-beta-adrenergic blocker.
Prescribed For
Heart failure, high blood pressure, angina pain, and cardiomyopathy.
General Information
Carvedilol was the first beta blocker approved for heart failure. It is also the only beta blocker approved for severe heart failure.
Carvedilol blocks both the alpha- and beta-adrenergic portions of the central nervous system. This dual action reduces the amount of blood pumped with each heartbeat and also decreases the risk of tachycardia (very rapid heartbeat). Carvedilol’s beta-blocking effects begin within an hour of taking the first dose; maximum blood-pressure-lowering occurs after 1 or 2 weeks. The drug also causes blood vessels to dilate (widen), allowing the heart to pump blood more efficiently.
Cautions and Warnings
Do not take carvedilol if you are allergic or sensitive to any of its ingredients, or if you have AV block, sick sinus syndrome or severe bradycardia (slow heart rate) without the use of a pacemaker.
Carvedilol should not be taken 13y patients with bronchial disease, qQQkVaS thronic bronchitis, emphysema, or asthma.
Carvedilol therapy should not be stopped suddenly due to the risk of worsening the heart condition.
In studies, carvedilol caused mild and reversible liver injury in about 1 of every 100 people who took it. Those with severe liver disease should not take this medication. Call your doctor at once if you develop signs of liver damage (symptoms include severe itching, dark-colored urine, flu-like symptoms, appetite loss, and yellowing of the skin or whites of the eyes).
Check with your doctor about continuing carvedilol if you are to receive general anesthesia; heart function that is depressed by anesthetics can worsen if carvedilol is used at the same time.
Make sure your doctor knows if you have diabetes. Carvedilol can mask signs of low blood sugar and may increase the effects of insulin or oral antidiabetes drugs, making it more difficult to recover from the effects of low blood sugar.
Carvedilol can mask symptoms of an overactive thyroid gland. Abruptly stopping carvedilol can trigger an attack of hyperthyroidism.
Possible Side Effects
Most side effects are considered mild or moderate.
✓    Most common: dizziness, sleepiness or sleeplessness, diarrhea, abdominal pain, slow heartbeat, dizziness when rising from a sitting or lying position, swelling of the hands or feet, sore throat, breathing difficulties, tiredness, back pain, urinary infection, and viral infection.
✓    Less common: extra heartbeats; palpitations; blood-pressure changes; fainting; reduced blood supply to the arms and legs (symptoms include aches, cramps, pain, or tiredness on walking, or pain in the foot, thigh, hip, or buttocks); tingling in the hands or feet; reduced sensation; depression; nervousness; constipation; gas; liver irritation; cough; impotence and reduced sex drive in men; itching; rash; visual difficulties; ringing or buzzing in the ears; high blood cholesterol, sugar, or uric acid; anemia; weakness; hot flushes; leg cramps; dry mouth; not feeling well; sweating; and muscle ache.
✓    Rare: Rare side effects can affect the heart, mental status, the respiratory tract, the urinary tract, and the kidney. It can also cause hair loss, weight gain, high blood-triglyceride levels, low blood-platelet counts, and sugar in the urine. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Carvedilol increases the effects of insulin and oral antidiabetes drugs. People taking this combination must monitor their blood sugar levels regularly. Call your doctor if there is any change from your normal pattern.
•    Carvedilol increases the effects of verapamil, diltiazem, and similar calcium-channel blocking drugs.
•    Monoamine oxidase inhibitor antidepressants may increase the effects of carvedilol.
•    Carvedilol increases the blood-pressure-lowering effect of clonidine. People taking this combination may need less clonidine to control their pressure.
•    Carvedilol increases the amount of digoxin in the blood by about 15%. Your digoxin dosage may have to be adjusted.
•    Cimetidine increases the amount of carvedilol absorbed into the blood by about 30%, but the importance of this interaction is not clear.
•    Rifampin reduces the amount of carvedilol in the blood by about 70%. Dosage adjustment is necessary.
•    Do not consume alcohol (including medicines that contain alcohol) within 2 hours of taking carvedilol.
Food Interactions
Take carvedilol with food to reduce the risk of dizziness or fainting.
Usual Dose
Heart Failure
Adult: 3.125 mg twice a day for 2 weeks. Dose may be doubled every 2 weeks to the highest level tolerated. Maximum daily dosage is 25 mg twice a day in people weighing less than 187 lbs., and 50 mg twice a day in people who weigh more.
High Blood Pressure and Cardlomyopathy
Adult: 6.25 mg twice a day to start, increased to 25 mg twice a day if needed.
Senior: Seniors may require smaller doses than younger adults. Child (under age 18): not recommended.
Overdosage
~3%rdose may lead to very low blood pressure (symptoms include dizziness and fainting), slow heartbeat and other cardiac symptoms, including shock and heart attack, breathing difficulties, bronchial spasm, vomiting, periods of unconsciousness, and seizures. Overdose victims must be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Carvedilol should be taken continuously. Do not stop taking it without your doctor’s knowledge, because abrupt withdrawal may cause chest pain, breathing difficulties, increased sweating, and unusually fast or irregular heartbeat. The dose should be gradually reduced over a period of about 2 weeks.
People taking carvedilol may become dizzy or faint when rising quickly from a sitting or lying position. If this happens to you, sit or lie down until you feel better. Carvedilol can also cause drowsiness, lightheadedness, or blurred vision. Be careful when driving or doing any task that requires concentration.
Contact lens wearers are more likely to experience dry eyes with carvedilol.
Swallow extended-release tablets whole; do not crush or break them.
It is best to take carvedilol at the same time each day. If you forget a dose, take it as soon as you remember. If it is within 4 hours of your next dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Animal studies indicate that carvedilol passes into the fetal bloodstream and may interfere with pregnancy. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
It is not known if carvedilol passes into human breast milk, though it passes into rat breast milk. Beta-blocking drugs like carvedilol may affect babies’ hearts. Nursing mothers who must take this drug should use infant formula.

Bisoprolol (bye-SOPE-roe-lol) 91
Brand Name
Zebeta
Combination Product
Generic Ingredients: Bisoproldl + Hydrochlorothiazide (0 Ziac
Type of Drug
Beta-adrenergic blocking agent.
Prescribed For
High blood pressure; may also be used for angina pectoris, and stable congestive heart failure.
General Information
Bisoprolol fumarate is one of many beta-adrenergic blocking drugs, or beta blockers, which interfere with the action of a specific part of the nervous system. Beta receptors are found all over the body and affect many body functions. Each beta blocker has particular characteristics that make it more suitable for certain conditions or people. Hydrochlorothiazide is a diuretic that lowers blood pressure.
Cautions and Warnings
Do not use bisoprolol if you are allergic or sensitive to it or other beta blockers.
Beta blockers should not be used by people with a slow heart rate, a condition called heart block (a disorder of the heart’s conduction system), or those in cardiac shock or overt heart failure_
Peoplewith angina who take bisoprolol for high blood pressure risk aggravating their angina if they suddenly stop taking the drug. These people should have their dosage reduced gradually over 1-2 weeks.
Bisoprolol should be used with caution if you have liver or kidney disease, because your ability to eliminate the drug from your body may be impaired.
People with chronic bronchitis or emphysema should use bisoprolol with caution.
Bisoprolol reduces the amount of blood pumped by the heart with each beat. This blood flow reduction may aggravate the condition of people with poor circulation or circulatory disease.
If you are undergoing major surgery, your doctor may want you to stop taking bisoprolol at least 2 days before surgery.
People with a history of severe anaphylactic reaction to allergens may be unresponsive to usual doses of epinephrine while taking beta blockers.
Possible Side Effects
Side effects are relatively uncommon and usually mild. T Mrnk common: impotence.
V Less common: unusual tiredness or weakness, slow heartbeat, heart failure, dizziness, breathing difficulties, bronchospasm, depression, confusion, anxiety, nervousness, sleeplessness, disorientation, short-term memory loss, Possible Side Effects (continued)
emotional instability, cold hands and feet, constipation, diarrhea, nausea, vomiting, upset stomach, increased sweating, urinary difficulties, cramps, blurred vision, rash, hair loss, stuffy nose, facial swelling, aggravation of lupus erythematosus, itching, chest pain, back or joint pain, colitis, drug allergy (symptoms include fever and sore throat), and liver toxicity.
Drug Interactions
•    Bisoprolol may interact with surgical anesthetics to increase the risk of heart problems during surgery. Some anesthesiologists recommend gradually stopping the drug by 2 days before surgery.
•    Bisoprolol may interfere with the normal signs of low blood sugar and with the action of oral antidiabetes drugs.
•    Bisoprolol increases the blood-pressure-lowering effects of other blood-pressure-reducing agents, including clonidine, guanabenz, and reserpine, and calcium channel blockers, such as nifedipine.
•    Aspirin-containing drugs, indomethacin, sulfinpyrazone, and estrogen drugs may interfere with the blood-pressurelowering effect of bisoprolol.
•    Cocaine may reduce the effectiveness of all beta blockers.
•    Bisoprolol may worsen the problem of cold hands and feet associated with taking ergot alkaloids, used to treat migraine. Gangrene is possible in people taking both an ergot and bisoprolol.
•    Calcium channel blockers, diphenhydramine, flecainide, contraceptive drugs, quinolone antibacterials, and quinidine may increase the amount of bisoprolol in the bloodstream and lead to increased bisoprolol effects.
•    Bisoprolol may increase the effects of ephedrine. Initially, high blood pressure wvd they a slow heart rate may result.
6 Combining beta blockers with lidocaine can increase lidocaine levels, possibly leading to toxicity.
•    Beta blockers taken with prazosin may increase the side effect of lightheadedness upon standing up that prazosin can produce.
•    Beta blockers may block the effects of epinephrine.
Smoking makes the liver break this drug down more quickly. If you stop smoking while taking bisoprolol, your daily dose
may have to be reduced.
Food Interactions
This drug may be taken without regard to food or meals.
Usual Dose
Adult: starting dose-5 mg once daily. The daily dose may be gradually increased up to 20 mg. Maintenance dose-5-10 mg once daily. People with kidney or liver disease may need only 2.5 mg a day to start. Seniors should be treated cautiously; they may respond to lower doses.
Child: not recommended.
Overdosage
Symptoms of overdose include changes in heartbeat—unusually slow, unusually fast, or irregular—severe dizziness or fainting, breathing difficulties, bluish fingernails or palms, low blood pressure, heart failure, shock, and seizures. The victim should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Do not stop taking bisoprolol unless directed to do so by your doctor. It is meant for continuous use. Abrupt withdrawal may cause chest pain, breathing difficulties, increased sweating, and unusually fast or irregular heartbeat. Dosage should be reduced gradually over a period of about 2 weeks when bisoprolol treatment is stopped.
Call your doctor at once if you develop back or joint pain, breathing difficulties, cold hands or feet, depression, rash, or changes in heartbeat. Bisoprolol may produce an undesirable lowering of blood pressure, leading to dizziness or fainting: call your doctor if this happens to you. Also call your doctor if you experiem:.epeisistent or bothersome anxiety, diarrhea, constipation, impotence, headache, itching, nausea or vomiting, nightmares or vivid dreams, upset stomach, trouble sleeping, stuffed nose, frequent urination, unusual tiredness, or weakness.
Bisoprolol may cause drowsiness, dizziness, blurred vision, or lightheadedness. Be careful when driving or performing complex It is best to take bisoprolol at the same time every day. If you forget a dose, take it as soon as you remember. If it is within 8 hours of your next dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Infants born to women who took a beta blocker while pregnant had lower birth weights, low blood pressure, and reduced heart rates. Bisoprolol should be avoided by pregnant women and women who might become pregnant while taking it.
It is not known if bisoprolol passes into breast milk. Nursing mothers taking bisoprolol should use infant formula.
Seniors: Seniors taking bisoprolol may be more likely to suffer from cold hands and feet, reduced body temperature, chest pain, general feelings of ill health, sudden breathing difficulties, increased sweating, or changes in heartbeat.

Few newborns are already capable of mounting an allergic reaction to dust mite. Actual symptoms of allergy may not appear for several months or years, but the essential first

step – making the allergy antibody, IgE, against the mite allergens – seems to have occurred already for some babies.
In situations where IgE does the job it is supposed to do –protecting against worms and other parasites (see p. 13) – this advance programming of the immune system before birth

has definite advantages. A child whose mother is infected with parasites is born with the ability to make IgE against those parasites, even though he or she has had no direct

contact with them before birth. The baby’s immune system has been forewarned of the likely hazards of life in the outside world.
While this is obviously valuable in conditions where parasitic infections are rife, emerging into a carpeted and well-upholstered world with IgE against dust mite already in the

bloodstream is a serious disadvantage, because it can pave the way for rhinitis and asthma. Given the trouble caused by dust-mite allergen, some doctors think that women should

try to reduce their exposure to it during the second half of pregnancy, so that little or none reaches the unborn child. At present it is not known for sure if this can make a

difference to the risk of allergies developing in a child, but it seems plausible.
What is pretty clear, from several previous studies, is that the level of house-dust mite in the home immediately after birth can make a distinct difference as regards the

chance of allergy developing. Minimising a newborn baby’s exposure to dust mite is worthwhile, and the measures needed to achieve this are described on pp. 244-5.
Carrying out these measures will raise the level of dust-mite allergen in the air temporarily, so it makes sense to do the work in the early stages of pregnancy (or – even

better – before conception), rather than expose yourself and the foetus to a tremendous burst of allergen later on in pregnancy. Or, get someone else to do the work, and stay

away while it is done.
There may be other potential allergens which you should try to eliminate from your home before the baby arrives, such as mould allergens (see p. 122).
Pregnancy
First and foremost – don’t smoke while you are pregnant, or afterwards (see box on p. 107). Any other smokers in the household should smoke outdoors.
What about your diet during pregnancy? Certainly you should eat a good balanced diet with plenty of fruit and vegetables. Taking a small supplement of vitamin E, or eating

plenty of sunflower seeds and oil, would be a good idea. Women with a low
intake of vitamin E and antioxidants (see p. 206) during pregnancy run a higher risk of having an allergic child.
Should you also avoid any foods? Food allergens, such as those from cow’s milk, do reach the foetus, passed from the mother’s blood to the baby’s blood via the placenta. And a

few babies are born already capable of making IgE against food allergens. On the basis of these findings, some doctors have suggested that avoiding potentially allergenic foods

(such as eggs, cow’s milk and peanuts) during pregnancy might help to reduce the risk of food allergy. However, evidence from research trials in which pregnant women followed a

restricted diet, and their children were later studied for allergies, does not show any convincing benefit. And in some studies, the women on restricted diets have not gained as

much weight as they should, and the babies have been slightly below average weight at birth. Most doctors now think that dietary restrictions during pregnancy are not worthwhile

– it is more important to eat well and get enough nutrients.
It does seem sensible not to overeat any particular food during pregnancy, although there is no scientific evidence on this point (simply because researchers have not yet looked

for such evidence). In particular, don’t overdo it with milk and milk products. Make sure you get enough calcium, obviously, but don’t force yourself to drink huge amounts of

milk, especially if you have any distaste for it. Talk to your doctor, midwife or health visitor about the possibility of a calcium supplement, if you dislike milk.
Breast-feeding
‘The cornerstone of allergy prevention is breast-feeding,’ according to Dr Erika Isolauri of Tampere University Hospital in Finland.
At one time, this would have been a controversial statement, but there is now a substantial body of scientific evidence to support the ‘breast-is-best’ idea in relation to

allergy prevention. A number of different studies have shown that exclusive breast-feeding, up to at least four months of age, reduces the risk of developing food allergy or

atopic eczema (or both) in the early years of life.
Exclusive means exactly that – no solids at all until after four months (and six months is better), and no supplementary feeds with infant formula, which is made from cow’s

milk, and therefore contains cow’s milk allergens. Unfortunately, it is sometimes far from easy to ensure that formula feeds are not given just after birth, by well-intentioned

nurses on the maternity ward. Given what we now know about the immune system of the newborn, this is the worst possible time to be delivering an onslaught of potentially

allergenic cow’s milk proteins.
Quite apart from the immediate effect of introducing cow’s milk allergens to the baby, a bottle can disrupt the development of a good breast-feeding relationship between mother

and child, and may lead to the early abandonment of breast-feeding.
Why should this happen? Firstly a different technique is needed for sucking on a bottle teat, and your baby may never develop the knack with nipples if given bottles at an early

stage. Secondly, allaying the baby’s hunger with a bottle can also mean that he or she demands less at the next breast-feed – and since the mother’s milk supply is partly

influenced by the level of demand, this can be detrimental. Some experts believe that occasional bottle-feeds can start a downward spiral of ever-diminishing supply from the

mother.
Dr Arne Host of the Department of Paediatrics at Odense University Hospital in Denmark, who has made a special study of breast-feeding, recommends giving a little boiled water

as a supplement during the first 3-4 days of life, if the breast milk supply is inadequate. After that time, the mother’s own supply should increase to meet the needs of her

baby. Introducing bottle-feeds at an early stage can prevent this delicate balance of supply-anddemand from ever being achieved.
Sometimes (though this is rare) despite everything being done just right, a mother’s supply of milk never quite matches her infant’s appetite. When this happens, and the child

concerned is from an allergy-prone family, the breast milk should be supplemented with an ultra-safe formula feed called a hydrolysate (see box on p. 66).
Hydrolysates should also be used for infants at high risk of allergy who, for whatever reason, cannot be breast-fed. Note that there are two categories of hydrolysate –

extensively hydrolysed formula and partially hydrolysed formula. For the purposes of allergy prevention, an extensively hydrolysed formula should always be used because it has

the lowest risk of causing food allergies.
Preparing to breast-feed
Because breast-feeding is natural, many first-time mothers just assume it will come naturally. Sadly, it often doesn’t.
Cracked nipples are a major obstacle. They are the equivalent of chapped hands, and are often caused by the baby not having ‘latched on’ correctly to the nipple. Help from an

expert breast-feeding adviser, right from the start. can avoid this problem.
Because cracked nipples are so sore, breast-feeding can then become a major ordeal rather than a pleasurable experience as it should be. What is more, infectious bacteria can

enter the breast through the cracks in the skin, causing mastitis, which is painful and may require antibiotic treatment: this is not necessarily a good thing for the baby (see

p. 247).
You can minimise the chance of cracked nipples by making the skin on the nipples tougher and more resilient, so that it does
not crack. Start during pregnancy, in about your fourth month. When you have a bath or shower, rub your nipples vigorously with your flannel for a few minutes. After three weeks

of this, graduate to a soft toothbrush, and brush them gently, then more firmly when they feel ready. Progress to a medium, and then a hard toothbrush.
Breast-feeding support groups can be immensely helpful, when you start breast-feeding, or when you feel things are not going right. Some groups have local advisers. all mothers

themselves with first-hand experience of breast-feeding. Having such an adviser with you, watching you breast-feed your new baby and making suggestions, or pointing out where

you are going wrong, can make all the difference. Look for such a group locally, and establish contact with them well before your due date. You may be able to have an adviser

with you at the birth, to help the baby take his or her first feed: this is of enormous value.
Having prepared yourself, you then have to prepare the nursing staff in the hospital where you will give birth, for the fact that you want to breast-feed exclusively. That means

no supplementary feeds from the staff – not even one bottle. The risks of this practice, in sensitising vulnerable babies to cow’s milk, are still not widely known, so you may

need to be persistent and make your feelings very clear. Talk to your midwife about this well before your expected delivery date, and find out what policy the hospital has about

supplementary feeds. Then see the relevant staff at the hospital.
The nurses are most likely to give the baby a bottle because he or she is crying while you are asleep, and they don’t want to wake you. Staff change all the time, so you will

probably need to put a notice on the crib or cot, to be certain that the baby is never bottle-fed while you are sleeping. If this seems ‘over-the-top’, consider the experience

of British researchers investigating allergy prevention who wanted to ensure that a group of newborns were never given supplementary feeds. They put warning stickers on both the

babies’ cots and the mothers’ beds, as well as asking the midwives and mothers to be very vigilant. Despite this effort, several of the babies being studied were given bottles.
Sometimes nurses give a bottle because they believe that the baby is not getting enough milk from the breast. The idea that mothers “don’t have enough milk”, and that this is

quite a common problem, is part of the medical folklore of breastfeeding today. In fact, true milk insufficiency is very rare. Most cases of poor milk supply arise because a

good breastfeeding relationship between mother and child is never established – and supplementary bottle feeds are partly to blame.
It is entirely possible that your milk supply will not be quite adequate in the first few days, but it should increase rapidly. The best thing, if breast- milk supply is

inadequate, is to give boiled water as a supplement during the first 3-4 days of life (see left).
Some preliminary evidence suggests that mastitis may alter the profile of immune cells in the milk, and that this might possibly increase the risk of the child’s own immune

system becoming allergy-prone. A key preventive measure is not to let the breasts become engorged with milk: the build-up of milk can lead on to mastitis. Learning to express

milk (by hand or with a breast pump) will be useful for times when your breasts feel over-full. Talk to a breast-feeding adviser.
Diet during breast-feeding
Pretty much everything you eat works its way into breast milk, though in very tiny amounts.
The food molecules that get through into breast milk can certainly affect babies who are already sensitised to a food. Cow’s milk is the classic example — cow’s milk proteins

get into human milk if the mother consumes any milk, cheese, yoghurt or other milk products. Babies who have already been sensitised to cow’s milk (by a supplementary

bottle-feed, for example, or even in the womb — see p. 241) react badly to the breast milk, unless the mother avoids all dairy products.
What is less certain is whether the traces of allergen in breast milk — cow’s milk allergen or that from any other food — might be capable of starting off allergy or

sensitivity. Are these minute traces enough to sensitise babies with a strong tendency to allergy? If they are, then mothers of high-risk infants might be well advised to avoid

certain allergenic foods while breast-feeding. Some studies do suggest that there is a reduction in food allergy if breast-feeding mothers avoid cow’s milk, eggs, nuts, fish and

soya. But if this restrictive diet makes your life impossible, then it is better to breast-feed your baby and eat what you like, than not to breast-feed at all.
Unfortunately, some babies do get eczema, in spite of being exclusively breast-fed. If this happens with your child, there are a number of steps you can take to deal with the

problem (see box on p. 248).
Treating the gut flora
Taking a probiotic or bacterial replacer (see p. 205) during the later stages of pregnancy, and continuing with this while breast-feeding, may reduce the risk of atopic eczema

in your child.
Weaning — when and how
The key to reducing the allergy risk for babies is to turn that old political jibe ‘too little, too late’ on its head. Research shows that, with weaning, it is ‘too much, too

early’ that increases the chance of allergic reactions developing. Suddenly presenting an infant of three months with a wide variety of solid foods, including potent allergens

such as eggs, peanuts and fish, can increase the likelihood of food allergy and/or eczema developing. Weaning late, with a limited number of safe foods, should be your goal.
At least four months of exclusive breast-feeding, and preferably six months, is now the standard recommendation for allergy prevention, and it is well supported by scientific

evidence.
But how long should breast-feeding continue after weaning begins? There is little concrete evidence here, but there is a strong belief in the medical community that

breast-feeding should go on for several more months, up to or beyond one year of age if possible, allowing the weaning process to be very gradual. The idea is to introduce new

foods one at a time, alongside breast milk.
As well as allowing the baby’s immune system lots of time to adjust to each new food, prolonged breast-feeding may help in another way as well. Recent research shows that breast

milk contains a great many substances which influence the baby’s immune system, nudging it in the right direction — away from any tendency to allergies.
Avoid those expensive little jars of ready-made baby food. Most contain potent allergens such as cow’s milk, wheat or soya. Making your own baby foods is not difficult, and is

the best way to ensure that your child gets only low-risk foods.
Reducing the risk of peanut allergy
Peanut oil, which contains traces of peanut allergen, is an ingredient of some skin creams. Recent research from the United States shows that babies treated with such creams

were seven times more likely to develop peanut allergy later. In the past, concern has focused on traces of peanut allergen that the baby swallows — either in the breast milk

(because the mother has eaten peanuts) or from her nipple cream. What this new research suggests is that peanut allergens absorbed through the baby’s skin are much
more likely to cause sensitisation. Don’t use any skin products if they have ‘Arachis oil’ or ‘Arachis hypogaea’ in the ingredients list — and steer clear of any cream without a

detailed ingredients list. In the same research study, soy formula also emerged as a risk factor: feeding a baby on this doubled the chance of peanut allergy developing later.

Good health is one of the most important things we can give our kids,’ says Martha, now in her sixties with two grown-up children.
`When I see how bad my daughter’s asthma is, and how hard her life is sometimes because of it, I do feel bad about the fact that I smoked when I was pregnant. But we just didn’t

know in those days. Even my doctor smoked. No one thought anything of it.
`I stopped when she was little, because it seemed to me that her wheezing got worse whenever I lit up. I’m sure that stopping then was better than nothing. It must have helped.
`In any case, there’s no point feeling guilty about things now - that won’t change anything. But if I’d known what damage it could do, I would have stopped sooner.’ Martha’s

regrets stem from the discoveries made in the past decade about the effects of smoking on allergies. We now know that smoking during pregnancy increases the amount of IgE (the

allergy antibody) in the blood of a newborn baby - an indication that he or she is at an increased risk of developing allergies. After the birth, exposing a child to cigarette

smoke continues to encourage high levels of IgE in the blood, as well as irritating the airways and making asthma more likely to develop.
The research on smoking is just one part of a worldwide research effort, during the past 20-30 years, into the possible causes of the allergy epidemic. That research can help

parents who are themselves atopic (allergy-prone) to reduce the risk of passing their allergy problems on to their children.
Who should be implementing these preventive measures? Firstly, any prospective parents who have allergies themselves, or had them as children. They are at higher risk (compared

to a non-allergic parent) of producing a child who is susceptible to allergies. The risk is especially high if both parents have or have had them at some point in their lives.
Secondly, these preventive measures could be worthwhile for parents who don’t have allergies themselves, but who come from atopic families (families with a tendency to allergy).

If you or your partner have brothers, sisters or parents with allergies, you are more likely than the average person to produce allergic children.
Finally, if you already have one allergic child - even though you and your partner don’t have allergies yourselves, and no one else in the family does - there is a

higher-than-average chance that subsequent children will have allergies. Your allergic child is a sign that the genes for allergy are there.
Given the important role that genes play in allergy (see p. 8), preventive strategies make a lot of sense for parents-to-be with allergies in the family.
Unfortunately, this is a topic which often generates confusion - some people assume that if a trait is genetic, it will inevitably come out in the child, and that nothing can be

done to prevent this happening. Although that is true for some inherited traits, such as metabolic abnormalities (see upper box on p. 75), it is not at all the case for allergy.
Developing allergic disease is not inevitable unless a child has a very big dose of the genes that favour allergy. Only a few children - generally those whose mother and father

are both badly affected by allergies - will come into this category. Even with these very high-risk children, following the measures described here will probably help to reduce

the severity of their allergic problems.
For most children at risk of allergies, even though they have some pro-allergy genes, there has to be an unfavourable environment to actually produce allergic disease.

‘Environment’ here means everything external that affects the child, including diet, air quality, allergens, diseases and medical treatment. Factors occurring before birth, such

as the mother’s lifestyle during pregnancy, are also part of the child’s environment. It is the interplay between genes and environment that will decide whether your child

develops allergies or escapes them.
This interaction is not a simple one, however, and different aspects of the environment operate in different ways. Firstly, there are some environmental factors that work at the

most fundamental level -conspiring with the pro-allergy genes to make the overall tendency to allergy far stronger. These are factors such as cigarette smoking by the mother

during pregnancy, or excessive hygiene during childhood, which influence the fundamental make-up of the child’s immune system. Secondly, there are environmental factors, such as

early exposure to house-dust mite or grass pollen, which can cause trouble by provoking specific allergic reactions. Note that factors like these will not become important

unless the allergic tendency is already there.
Efforts to reduce the risk of allergy operate on both types of factor.
On the one hand, there are measures such as quitting smoking or easing up on hygiene, which tackle the allergic predisposition itself. These measures are, in effect, trying to

make a Western child’s immune system more like the immune system of a child from a poor rural village in the developing world, whose chance of developing allergy is very low

indeed.
On the other hand, there are measures such as reducing dust-mite levels, that try to stop the development of particular allergic reactions.
Obviously, if measures of the first kind could be truly successful, there would be little or no need for measures of the second kind. But this kind of success is very difficult

to achieve in modern Western society. Although we can certainly improve matters a great deal, and lessen the tendency to allergy, the conditions that would completely reverse it

are beyond our reach at present. So both kinds of preventive measure remain necessary.
In reading the pages that follow, it is important to keep things in perspective, and not feel excessively anxious about your child. Do what you can, but don’t feel guilty if you

can’t manage everything that is suggested here. And if you already have a child with allergies, please don’t feel guilty about things that might have contributed to this. Only

hindsight is perfect, and you no doubt did the best you could, given the information you had at the time, and the many other constraints and difficulties that you faced. That is

the best that any of us can do.

Breathing Exercises
Breathing is a delicate art, and it is possible to get it wrong, in a variety of ways and for a variety of reasons. A poor breathing pattern can gradually become habitual,

without the person concerned being aware that his or her breathing is at all abnormal.
Allergy and sensitivity reactions sometimes play a part in causing abnormal breathing, and the symptoms produced by a poor breathing pattern may then augment the symptoms of

sensitivity, creating a vicious circle. Correcting an abnormal breathing pattern, by means of breathing exercises and re-training, can produce remarkable improvements in health

for some people.
Breathing too much
Taking in too much air, often called over-breathing or hyperventilation, is the most common breathing disorder. It can produce a variety of rather strange symptoms (see p. 227)

that are sometimes diagnosed correctly, and treated appropriately, but often get overlooked or misdiagnosed.
The primary purpose of breathing is to obtain oxygen from the air and absorb it into the blood. The lungs are a crucial interface here, a trading post for gases that are

exchanged between the bloodstream and the external air. The delicate, moist membranes that cover the inner surface of the lungs are accessed by millions of tiny thread-like

blood vessels known as capillaries. Oxygen from the air seeps into the blood through the thin walls of these capillaries. At the same time, the lungs clean the blood of carbon

dioxide, a waste gas produced by the body’s metabolism. As oxygen seeps into the blood, carbon dioxide seeps out.
That is the school-textbook view of breathing, and it is correct up to a point. But it is over-simplified and misleading if it simply portrays oxygen as totally
good and carbon dioxide as totally bad. In fact, there is a correct level in the blood for both gases, and too little or too much of either can cause problems.
Carbon dioxide plays an important role in the equilibrium of the blood because, when dissolved in any liquid, carbon dioxide makes a weak acid. So the amount of carbon dioxide

present is crucial in deciding the acidity of the blood. Given that the blood reaches every part of the body, it is not surprising that any changes from its normal composition

have far-reaching effects.
Normally, blood is very slightly acidic, and that is what the body is accustomed to. While some body parts can cope with small changes in the acidity of the blood, other parts

respond very badly. The nerve cells are particularly vulnerable to changes in acidity.
Hyperventilation, or over-breathing, has relatively little effect on the level of oxygen in the blood, which is carefully controlled, but it can lower the level of carbon

dioxide in the blood, thus making it less acid. More commonly, hyperventilation just makes the level of carbon dioxide vary a great deal.

When the carbon dioxide levels in the blood yo-yo about all the time, this has some unpleasant effects. In particular, it disrupts the smooth running of the nerve cells, which

is why many of the symptoms of hyperventilation involve the senses, feelings or behaviour.
The symptoms of hyperventilation can include:
•    numbness or pins-and-needles in the hands and feet, occasionally affecting the lips and tongue as well
•    difficulty in swallowing
•    aching muscles, cramps, tremors and twitches
•    sudden loss of strength in the muscles
•    dizziness, confusion, unreal or spaced-outfeelings
•    blurred vision, ringing in the ears
•    headache, migraine
•    breathlessness
•    aching in the chest
•    abnormal heart rhythm
•    sensitivity to bright lights and loud noises.
There may also be some severe psychological symptoms:
•    panic – a brief but intense state of anxiety
•    prolonged anxiety or depression
•    hallucinations, although this is rare
•    mood swings and phobias, most frequently a fear of dying. The irrational conviction that death is imminent can be overwhelming, even in someone who is young and

apparently in good health.
Each of these symptoms can, of course, be caused in several other ways, but when this whole cluster of symptoms – or a large number of them –occurs together in an individual,

that person is very likely to be a hyperventilator.
When there are short self-contained bursts of hyperventilation, the effects are often described as a panic attack. Doctors usually have no trouble recognising this problem, but

– not surprisingly – are often misled by the sustained psychological symptoms of chronic (long-term) hyperventilation. Many people with chronic hyperventilation are diagnosed as

having some kind of mental illness, and they may go for years without getting the right diagnosis.
Hyperventilation and sensitivity reactions The link between sensitivity reactions and hyperventilation seems to be a complex one. Unfortunately, very little research has been

done in this area, so what follows is based on the case-histories of patients, and the collective experience of doctors, not on hard scientific data.
In some cases, a sensitivity reaction may
directly provoke a change in breathing pattern. This
is what appears to happen for some people with
caffeine sensitivity. Cutting out all caffeine-con-
taining drinks (coffee, tea and colas) seems to put a
stop to the hyperventilation symptoms, because the
multiple symptoms promptly disappear (see p. 235).
In other cases, a severe sensitivity problem such
as multiple chemical intolerance results in an anxious
state of mind, and the anxiety leads to hyperventi-
lation. Hyperventilation, pure and simple, may also
masquerade as chemical intolerance (see p. 236).
Wheezy as a mountain breeze
Ionisers — devices that supposedly turn indoor urban air into a fresh mountain breeze — are often promoted as alternative devices that can clear allergens from the air. They do

remove some allergens, but in the case of asthma, research shows that some ionisers can actually make symptoms worse, by generating ozone which irritates the airways. It is

usually the cheaper ionisers that do this. More expensive models are less likely to produce ozone, but they are unlikely to help either. Several scientific trials show that

ionisers have no significant benefits when used by asthmatics.
Hyperventilation and asthma
While hyperventilation can develop in anyone, asthmatics are particularly vulnerable. During an asthma attack, especially a severe one, developing an abnormal breathing pattern

is an entirely understandable reaction. In an attempt to get more air, you may start breathing more rapidly and taking air into the upper chest, using the accessory muscles of

breathing (see p. 230). These muscles should not normally be used when you are at rest — they exist to give you extra breathing capacity when running fast.
As long as the asthma attack lasts, this forced breathing does no harm, because its effects are cancelled out by the narrowing of the airways. But if this over-breathing

persists after the attack has ended, then too much air is going in and out of the lungs, so carbon dioxide levels in the blood begin to fall.
Simply feeling anxious can also trigger off rapid upper-chest breathing. If you get very worried when an asthma attack starts, you may begin hyperventilating just out of

anxiety.
For asthmatics, in addition to the usual symptoms of hyperventilation (see p. 227) there are some subtle effects of hyperventilation that can make asthma worse:
•    The airway muscles (and all other muscles that are not under voluntary control) contract slightly when carbon dioxide levels in the blood fall.
•    Mast cells are quicker to degranulate (see box on p.12) when
there is less carbon dioxide, and this triggers allergic symptoms. Just to complicate matters, one of the symptoms of hyperventilation is breathlessness. Sometimes this is the

most prominent symptom in non-asthmatic hyperventilators, and the doctor overlooks the other symptoms and gives a diagnosis of asthma. In such cases, people are told they have

asthma when they are actually suffering from hyperventilation alone.
Testing for hyperventilation
You can do two simple tests for hyperventilation at home, if you think that it could be playing a part in your symptoms. (If you are asthmatic, only do these tests when you have

no asthma symptoms and your peak-flow reading is good. Make sure your reliever inhaler is nearby, in case of a bad reaction to the test.)
The first test should be done when you have some symptoms that might indicate hyperventilation (see p. 227).
Find a clean paper bag and hold it over your nose and mouth while breathing normally. Any symptoms that are due to hyperventilation should clear up, because, by re-Inhaling the

air that you have just breathed out, you will increase the level of carbon dioxide in your blood.
The second test is done when you don’t have any of the symptoms listed for hyperventilation.
Speed up your breathing, and inflate your upper chest with each breath. Do this for a few minutes. Do any of your usual symptoms appear? If they do, this suggests that they may

be caused by hyperventilation.
If either of these tests indicates hyperventilation, make an appointment to see your doctor. It is important that you should have a proper medical diagnosis, so that you get the

right professional treatment.
Treating hyperventilation
If you hyperventilate, you could be taught a more healthy breathing pattern by a physiotherapist — ask your doctor for a referral. Certain complementary therapists, such as

osteopaths and Feldenkrais practitioners, can also teach good breathing patterns, and so can experienced yoga teachers (see p. 224). A teacher or therapist who works at a

relaxed pace, is not too dogmatic, and helps you to find your own way to healthy breathing, is preferable to one who tries to impose a regimented breathing pattern on you.
On the assumption that most hyperventilators don’t just over-breathe, but also breathe with their upper chest and under-use the diaphragm (see pp. 229-230), all these different

practitioners will take a combined approach — tackling both sides of the problem at once. This represents an important difference from the Buteykc, method (see below).
The Buteyko method
The stated aim of the Buteyko method (also called the Buteyko treatment) is to stop people from hyperventilating. However, Buteykc, practitioners do not work with people who

have the symptoms of hyperventilation, as recognised by conventional medicine (see p. 227). Instead they work with asthmatics — any asthmatics, not just those whose symptoms

suggest that they might be hyperventilators.
The rationale for this is the claim, by the originator of the exercises, Professor Konstantin Buteyko, that asthma is actually caused by hyperventilation. (What is more,

Professor Buteyko cites hyperventilation as the cause of no fewer than 150 different diseases, including allergies, eczema, migraines, insomnia, bronchitis, high blood pressure

and haemorrhoids. However, his treatment is only marketed for asthma.)
The claims made for the success of the Buteyko method in treating asthma are startling. According to one training centre, it can get 97% of asthmatics off most of their drugs

and able to control attacks within a week of starting.
Not surprisingly, this is a bit of an exaggeration. But the real achievements of the Buteykc, method are still quite impressive: an Australian research study showed that during

the course of Buteyko lessons, the overall use of reliever inhalers (e. g. Ventolin) fell substantially and remained relatively low three months later. However, the patients’

average peak flow stayed the same, and 15% of those studied were admitted to hospital with a severe asthma attack during the trial. In the eight months that followed, 30% needed

a course of steroid tablets – indicating a substantial worsening in their condition. In other words, the Buteyko method can give some help to many asthmatics, but the claim that

it can get almost everyone off asthma drugs and free of asthma is just hype.
Professor Buteyko’s claim to have discovered the fundamental cause of asthma is clearly untrue. What he seems to have discovered is that there are many more hyperventilators

among asthmatics than was widely realised, and that they generally show no obvious symptoms of hyperventilation. His other important contribution is to suggest that

mouth-breathing may create a lot more problems for asthmatics than previously recognised.
The Buteyko method has three aspects:
•    unblocking the nose
•    training to breathe through the nose, not the mouth
•    training to take fewer breaths and pause between breaths. Unlike other treatments for hyperventilation (both conventional and alternative), the original Buteyko method

pays no attention to teaching asthmatics to breathe with the diaphragm. However, a few Buteyko practitioners are now beginning to incorporate this aspect of treatment.
If you decide you would like to try the Buteyko method, there are several different options. Classes are the most expensive route, with very high fees being charged. There are

video cassettes you can buy, which are less expensive. Alternatively, there are various books, which are much less costly, and which explain how to do the exercises (see p.

255).
Whichever option you choose, it is vital that you get your doctor’s permission before starting. Ensure that your reliever inhaler is in your pocket while doing the exercises,

because they could provoke an asthma attack. Keep taking your preventer drugs regularly throughout the treatment. If you start to feel much better and want to reduce your dose

of preventer, you must talk to your doctor first.
Don’t follow the Buteyko method blindly, because some of the advice given is dangerous. For example, some Buteyko publications advise you to refuse oxygen if you are taken to

hospital with a severe asthma attack. They claim that oxygen levels in the blood are not reduced during a severe asthma attack, but this is just not true. Measurements clearly

show that the level of oxygen
gets very low, and this is frequently the cause of death.
Another very peculiar Buteyko idea is that you should not try to shift mucus from your airways because mucus ‘protects you’ against losing too much carbon dioxide. This too is

dangerous advice. Accumulated mucus narrows the airways, adding to your asthma symptoms, and it can even block a small airway completely. The part of the lung served by that

airway then collapses – a serious complication that no asthmatic would want.
Using the right muscles
Hyperventilation is often linked with an abnormal way of breathing, in which the wrong muscles are used. This is one common pattern that conventional doctors recognise for

hyperventilators:
•    The main muscle of breathing – the diaphragm (see below) is not used fully
•    The muscles of the upper chest become involved in breathing, even at rest, when they should not be needed
•    There are lots of rapid, shallow breaths
•    The breathing is quite irregular, with deep, sighing breaths from time to time, or frequent yawning.
Even in those who do not hyperventilate, breathing with the upper chest, and/or neglecting the diaphragm, can become a problem. This pattern of breathing is sometimes linked to

anxiety and emotional problems (see p. 230).
To understand what goes wrong, you need first to know about the healthy way to breathe.
The rib-cage and the diaphragm are the work-horses of breathing. You can feel your rib-cage through your skin, and feel its movements, but the diaphragm is far more

inaccessible. It lies below the lungs, but above the stomach and intestines.
In its contracted state, the diaphragm becomes a thick slab of muscle, with a slight curve, like an inverted saucer. When it relaxes, it becomes far more curvaceous, changing to

a shape like an inverted bell. In this shape, there is less space for the lungs above the diaphragm.
If you are breathing correctly, the diaphragm contracts when you breathe in and relaxes when you breathe out. The contraction lowers the dome of the diaphragm, pulling the base

of the lungs downwards and so making them expand.
Breathing out requires no muscular force whatever, as long
as you are just sitting or walking about (and therefore not breath-
ing hard). The lungs are naturally elastic, like balloons, so they
automatically contract and force out the air, once the diaphragm
relaxes into its bell-like shape and stops pulling them downwards.
While you cannot feel the diaphragm itself, you can feel the
effect of its in-breath contraction. As it contracts, the diaphragm
pushes down on the stomach and intestines, so that your abdomen bulges out a little with each breath. Western women, conditioned to admire an unnatural flat-bellied body shape

(unnatural for a woman, that is), often breathe badly because they are trying to ‘hold the tummy in’. This steely tightening of the muscles across the front of the abdomen

opposes the contraction of the diaphragm, and prevents a natural and relaxed in-breath.
The diaphragm should do virtually all the work of breathing in, when you are not exerting yourself much. The upper part of the rib-cage should hardly expand at all and the

muscles that run between the ribs, the intercostal muscles, should not be working.
When you become more active, and therefore need more oxygen, the upper chest automatically starts to expand with each in-breath. At this point the intercostal muscles become

involved, along with a whole team of other muscles in the chest region —these are known as the accessory muscles of breathing.
The effects of an asthma attack
In the grip of a severe asthma attack, you may well start using the accessory muscles of breathing to try to take in more air. If you have frequent attacks, or if this way of

breathing gets to be a habit and goes on between attacks, then the chest may be distorted by the constant use of the accessory muscles, plus the over-inflation of the lungs.

Severe asthmatics often have high shoulders and a `barrel-chested’ look as a result of this. Hyperventilation may also start in this way.
Observing how you breathe
To discover whether you are breathing with your diaphragm or your upper chest, lie on your back with your left hand on your belly, and your right hand on your upper chest. Just

lie still for a few minutes, let your arms relax, then start to pay attention to your hands. When you breathe in, which hand rises? It should be the left hand, with little or no

movement in the right.
Alternatively, bend over and hold the back of a chair with your hands. Your back, head and arms should form a straight horizontal line, at right angles to your legs. Just stay

quietly in this position for a while. It is very difficult to breathe with the upper chest in this pose, whereas breathing with the diaphragm is easy. If you feel fine in this

position, then you are probably breathing well normally.
Correcting upper-chest breathing
Learning to breathe with the diaphragm is often an important part of correcting hyperventilation (see p. 228). It should also be taught to anyone who has the kind of chest

deformities that develop in severe asthma (see above).
Diaphragmatic breathing, or abdominal breathing as it is sometimes called, should help make you feel more relaxed
because the in-breath can disperse tensions in your abdomen. This is where many people ‘hold on to’ their fears, with chronically tense abdominal muscles. When you start

breathing into this area of tension, it is important to take things gently and not force the breath downwards. Be aware of any resistance to the in-breath in the abdomen, and of

any emotional reactions that occur when you challenge this resistance.
Sometimes breathing in this way for the first time can bring up emotional difficulties that may need careful handling. That is why it may be better to learn abdominal breathing

from someone who has time to deal with such issues, and with whom you feel very comfortable and relaxed — for example, a yoga teacher or an alternative therapist who you like

and trust. Physiotherapists tend to take a very brisk and practical approach to breathing, which may not be entirely appropriate or helpful when habitual ways of breathing are

tied up with emotional problems.
When learning to breathe with the diaphragm, be careful not to get carried away and become a ‘belly breather’, whose every in-breath sends the abdomen bulging out like a

mainsail. The abdominal muscles should oppose the downward movement of the diaphragm to some extent, without being too tense.
Clearing the nose
Breathing through the nose, rather than the mouth, is beneficial for asthmatics, because it cleans and warms the air. It can also help those with chronic sinusitis because it

oxygenates the air in the sinuses, which discourages some of the more troublesome microbes responsible for sinus infections.
This technique for clearing a blocked nose, part of a set of breathing exercises for opera singers, is based on a time-honoured yoga exercise called alternate nostril breathing:
•    Sit with your mouth closed.
•    Press your right nostril against your nose to close it, using the thumb of your right hand.
•    Breathe out through your left nostril.
•    Press your left nostril against your nose with the index finger of your right hand, to close it. (The hand makes only a very small movement from side to side.)
•    Breathe in through your right nostril.
•    Repeat the sequence.
Once you have got the hang of this, do ten fairly rapid breaths, with no pause between out-breath and in-breath. Pause and rest.
Repeat using your left hand, and reversing the flow of the breath: out through the right nostril and in through the left. Again, do ten breaths and then rest.
Alternatively, try the following exercise, which is recommend by Buteyko practitioners for unblocking the nose. This technique has not been tested scientifically, but the

reports of asthmatics who have used it suggest that it often works wonders, even with children who could never breathe through their noses previously:
•    Have your reliever inhaler to hand, just in case the exercise brings on an asthma attack.
•    Breathe as you do normally, and at the end of a normal out-breath, close your mouth and hold your nose
•    Stay like this, without inhaling, for as long as you can without discomfort. Walk around the room while you are doing this or, if you are young and fit, do something

more strenuous – either walk upstairs or squat-then-stand several times.
•    When you need to breathe in, keep your mouth shut but release your nose
•    Breathe in slowly through the nose
•    Repeat the exercise if your nose becomes blocked again.
Special exercises for asthma
In addition to tackling the problem of hyperventilation, if one exists, asthmatics can use other breathing exercises to tackle specific aspects of their asthma.
Clearing mucus from the lungs A physiotherapist can teach methods of clearing mucus from the airways which are suitable for asthmatics. Ask your doctor for a referral. You could

also try the following exercises:
Huffing Take an in-breath, then tighten your abdominal muscles very sharply, to push the air out. Imagine there is a candle in front of you, and you are trying to extinguish it,

but using your belly muscles only. Your out-breath should make a short soft ‘huff’ sound – if it is more of a loud ‘w000sh’, you are contracting the muscles in your chest as

well as those in the belly. Try again, and focus your attention on your belly as you make the out-breath.
The in-breath should be effortless with this exercise – it just bounces back in. Do as many huffs as you can without feeling breathless. Rest and repeat. The aim is to build up

stamina until you can do 30 or more huffs in succession.
Pursed-lips breathing Take a fairly deep in-breath, then purse your lips together. As with huffing, your belly muscles have to do all the work of the out-breath, but in this

exercise they are working against the muscles of the lips. The aim is to divide the out-breath into as many fragments as possible – to push the air out through the lips in a

succession of tiny, forceful blasts.
One objective of these exercises is to encourage mucus to start moving up to the top of the airways. From there, it can be cleared with a little throat-clearing cough. Note that

the mucus will probably take a while to reach the throat – this may happen some time after you do the exercise. For maximum effect, repeat these exercises several times each

day.
Coping with asthma attacks
The crucial thing during an asthma attack is to focus on your out-breath, not your in-breath. Of course this goes against the grain, because you feel so desperate for air, but

remember that the central problem is stale air from your last in-breath, now trapped in your lungs by the narrow airways. If you can focus on exhaling this used air, you will

have more space for fresh air to come in with the next in-breath.
At times when you are not suffering from an asthma attack, it is worth doing some exercises that improve the strength of your out-breath. The key problem during an asthma attack

is that the natural elasticity of the lungs, which should power the out-breath, is not equal to the challenge of pushing out all that air through narrowed airways in a short

space of time. In this situation, contracting your abdominal muscles so that they push upwards and assist in emptying the lungs is helpful.
The two exercises described above for clearing mucus –huffing and pursed-lips breathing – also strengthen those abdominal muscles which can assist you with your out-breath

during asthma attacks.
Strengthening exercises
Several different exercises or pursuits that strengthen the breathing muscles seem to produce an improvement in asthma. The reasons for this are not understood.
Asthmatics who take up a wind instrument, such as the flute, often report that their asthma improves considerably. The same effect has regularly occurred with asthmatics who

undertake classical training in singing. One set of exercises, taught to aspiring opera singers and designed specifically to strengthen the diaphragm, has been scientifically

tested and shown to improve asthma and reduce the need for drugs. These exercises can be learned at home (see p. 255). There are also some mechanical devices which can

strengthen the breathing muscles (see p. 255).
