Prescribed For
A wide variety of disorders from rash to cancer, including adrenal disease, adrenal hormone replacement, bursitis, arthritis, severe skin diseases including psoriasis and other rashes, severe or disabling allergies, asthma, drug or serum sickness, attacks of multiple sclerosis, severe respiratory diseases including pneumonitis, blood disorders, gastrointestinal (GI) disease including ulcerative colitis and Crohn’s disease, and inflammation of the nerves, heart, or other organs. Dexamethasone is also used to treat mountain sickness, vomiting, bronchial disease in premature babies, excessive hairiness, and hearing loss associated with bacterial meningitis. Fludrocortisone is used to treat Addison’s disease and for symptomatic orthostatic hypotension. Prednisone is used to improve strength and function of some muscular dystrophy patients. Methylprednisolone is used to decrease mortality in some patients suffering from severe alcoholism and chronic active hepatitis.
General Information
Produced by the adrenal gland, natural corticosteroids are hormones that affect almost every body system. The major dMeyences among corticosteroid drugs are potency and variation in secondary effects, 0OZ10r preference and past experience with a Mftosferoid usually determine which drug to prescribe for a specific disease.
Cautions and Warnings
Do not use an oral corticosteroid if you are allergic or sensitive to any of its ingredients.
Corticosteroids may mask symptoms of an infection. Because these drugs compromise the immune system, new infections may occur during corticosteroid treatment; when this happens, a relatively minor infection that would respond to ordinary treatment can turn serious. Corticosteroids may impair immune response to hepatitis B, prolonging recovery. They may reactivate dormant amebiasis (a parasitic infection). Corticosteroids should not be taken if you have a fungal blood infection, because they can allow the infection to spread more easily. They should be used with caution by people with herpes eye infection, tuberculosis or in any other bacterial, fungal, or viral infections.
Long-term use of any corticosteroid may increase the risk of developing cataracts, glaucoma, or eye infections, especially viral or fungal.
When stopping a corticosteroid, dosage must be reduced gradually under a doctor’s supervision—otherwise you may experience adrenal gland failure.
If you are taking large corticosteroid doses. you should not receive any live virus vaccine because corticosteroids interfere with the body’s reaction to the vaccine.
Hydrocortisone and cortisone may lead to high blood pressure. Other corticosteroids are less likely to affect blood pressure.
Corticosteroids should be used with caution if you have severe kidney disease.
High-dose or long-term corticosteroid therapy may aggravate or worsen stomach ulcers. This may occur when total dosage reaches 1000 mg of prednisone, 150 mg of betamethasone or dexamethasone, 5000 mg of cortisone. 4000 mg of hydrocortisone, 1000 mg of prednisolone, or 800 mg of methylprednisolone.
People who have recently stopped taking a corticosteroid and are going through a period of stress may need small doses of a rapid-acting corticosteroid, such as hydrocortisone, to get them through this period. Call your doctor if you think you might be experiencing this kind of stress reaction.
Use corticosteroids with caution if you have had a recent heart attack or have, Colitis, heart failure, high blood pressure, blood-clotting tendencies, thrombophlebitis, osteoporosis, antibiotic-resistant infections, Cushing’s disease, myasthenia gravis, metastatic cancer, diabetes, underactive thyroid disease, cirrhosis of the liver, or seizure disorders.
corticosteroid psychosis (symptoms include euphoria or feeling “high,” delirium, sleeplessness, mood swings, personality changes, and severe depression) may develop in people taking dosages greater than 40 mg a day of prednisone. These symptoms may also develop with other corticosteroids taken in equivalent doses (see “Usual Dose” for relative equivalencies). Symptoms of corticosteroid psychosis usually develop within 15-30 days of beginning treatment. These symptoms may also be linked to other factors—women and those with a family history of psychosis are more at risk.
Corticosteroids can cause loss of calcium, which may result in bone fractures and aseptic necrosis of the femoral and humorai heads (a condition in which the large bones in the hip degenerate from loss of calcium).
Prednisone may aggravate emotional instability.
Corticosteroids do not cure multiple sclerosis (MS) or slow its progression, though they may speed recovery from attacks of the disease.
. Corticosteroid products often contain tartrazine dyes and sulfite preservatives. Many people are allergic to these chemicals.
Possible Side Effects
✓    Most common: headache, respiratory infections, acne, and bruising.
✓    Common: water retention (swollen ankles), back pain, heart failure, upset stomach (possibly leading to stomach or duodenal ulcer), potassium loss, dizziness, fatigue, insomnia, weight gain, increased appetite, nausea, stomach gas, abdominal pain, general pain, muscle weakness, loss of muscle mass, slowed healing of wounds, increased sweating, allergic rash, itching, convulsions, excess hair growth, and worsening of a pre-existing psychiatric condition.
✓    Less common: irregular menstruation; slowed growth in children, particularly after lengthy periods of corticosteroid treatment; adrenal or pituitary gland suppression; diabetes; drug sensitivity or allergic reactions; blood clots; moon face; feeling unwell; euphoria; mood swings; personality Changes; and severe depression.
♦    Rare: Rare side effects can appear in any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Tell your doctor if you are taking any oral anticoagulant (blood-thinning) drug. If you begin taking a corticosteroid, your anticoagulant dosage may have to be adjusted.
•    Combining a corticosteroid and a diuretic such as hydrochlorothiazide may cause loss of blood potassium. Low blood potassium may increase the side effects of digitalis drugs.
•    Contraceptive drugs, estrogen, erythromycin, azithromycin, clarithromycin, and ketoconazole may increase the risk of corticosteroid side effects.
•    Barbiturates, aminoglutethimide, phenytoin and other hydantoin anticonvulsants, rifampin, ephedrine, colestipol, and cholestyramine may reduce the effectiveness of corticosteroids.
•    Corticosteroids may decrease the effects of aspirin and other salicylates, growth hormones, and isoniazid.
•    Combining a corticosteroid and a theophylline drug may require a dosage adjustment of either or both drugs.
•    Corticosteroids may interfere with laboratory tests. Tell your doctor if you are taking any of these drugs so that tests are properly analyzed.
•    Limit your intake of alcohol while on oral corticosteroids.
Food Interactions
Take corticosteroids with food or a small amount of antacid to avoid stomach upset. If stomach upset continues, notify your doctor. Grapefruit juice doubles the amount of some oral corticosteroids absorbed into the blood.
Usual Dose
Once-daily doses should be taken in the morning. Dosages vary greatly and depend upon the specific disease being treated. Dosages for infants and children should be individualized according to severity of disease and response to treatment.
Betamethasone: starting dosage-0.6-7.2 mg a day. Maintenance 1609age-0.6-7.2 mg a day.
Budesonide: 9 mg a day.
Cortisone: starting dosage-25-300 mg a day. Maintenance dosage-25-300 mg a day.
Dexamethasone: 0.75-9 mg a day. Daily dosage sometimes exceeds 9 mg. A temporary dosage increase may be necessary it you are experiencing emotional stress. In alternate-day therapy, twice the usual daily dose is taken every other day.
Hydrocortisone: 20-240 mg a day.
Methylprednisolone: starting dosage-4-48 mg or more a day. Maintenance dosage varies. A temporary dosage increase may be necessary if you are experiencing emotional stress. in alternate-day therapy, twice the usual daily dose is taken every other day.
Prednisone and Prednisoione: 5-60 mg a day. Daily dosage sometimes exceeds 60 mg. A temporary dosage increase may be necessary if you are experiencing emotional stress. In alternate-day therapy, twice the usual daily dose is taken every other day.
Equivalent doses: Using 5 mg of prednisone as the basis for comparison, equivalent doses of other corticosteroids are 0.6 mg-0.75 mg of betamethasone, 25 mg of cortisone, 0.75 mg of dexamethasone, 20 mg of hydrocortisone, 4 mg of methylprednisolone, and 5 mg of prednisolone.
Overdosage
Symptoms of overdose are anxiety, depression or stimulation, joint or muscle pain, blurred vision, stomach bleeding, increased blood sugar, high blood pressure, and water retention. The victim should be taken to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special Information
Do not stop taking this medication without your doctor’s knowledge. Suddenly stopping any corticosteroid drug may have severe consequences; the dosage must be gradually reduced by your doctor.
G& your doctor if you develop unusual weight gain, black or tarry stools, swelling of the feet or legs, muscle weakness, vomiting of blood, menstrual irregularity, prolonged sore throat, fever, cold or infection, appetite loss, nausea and vomiting, diarrhea, weight loss, weakness, dizziness, or low blood sugar.
If you take several doses a day and forget a dose, take the dose you forgot as soon as possible. It it is almost time for your next dose, skip the one you forgot and double the next dose. If you take 1 dose a day and forget a dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
If you take a corticosteroid every other day and forget a dose, take it immediately if you remember it in the morning of your regularly scheduled day. If it is much later in the day, skip the dose you forgot and take it the following morning, then go back to your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Studies have shown that long-term corticosteroid therapy at high dosages may cause birth defects, as may chronic corticosteroid use during the first 3 months of pregnancy. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
Corticosteroids taken by mouth may pass into breast milk. Most nursing mothers who must take a corticosteroid should use infant formula, though low dosages of some of these drugs may be taken for short periods while breast-feeding. Consult your doctor.
Seniors: Seniors are more likely to develop high blood pressure while taking an oral corticosteroid. Older women are more susceptible to osteoporosis (a condition characterized by loss of bone mass due to depletion of minerals, especially calcium) associated with high dosages of oral corticosteriods. Lower dosages are just as effective in seniors and cause fewer side effects.

Prescribed For
Inflammation, itching, eczema, dermatitis, vitiligo (patchy loss of skin color), blistering skin diseases, lupus and other connective tissue diseases, psoriasis, and many other specialized skin problems; may also be used to Weal severe diaper rash.
General Information
Topical corticosteroids do not cure the underlying cause of skin problems, but they can relieve symptoms of rash, itching, or inflammation by interfering with the body mechanisms that produce them. You should never use a topical corticosteroid without your doctor’s knowledge because it could mask a symptom important in diagnosing your condition. Also, improper use of a topical corticosteroid could lead to unwanted and sometimes permanent side effects. In general, ointment forms of topical steroids are more potent and usually more effective than cream or lotion forms. Ointments are also less likely to cause allergic reactions because they contain fewer inactive ingredients.
Generic products in this group can vary in potency and produce different results from their brand-name counterparts, even though they contain the identical quantity of active ingredient. Topical steroids are rated from 1 (most potent) to 7 (least potent). Generally, products within a potency class are interchangeable. Ask your doctor or pharmacist which products are interchangeable. The lowest potency products are available without a prescription. Ointments tend to be more potent than creams and solutions and different product concentrations affect their classification.
Super-potent topical corticosteroids (class 1) should not be used on the face, neck, under the arms, or in the groin area. These products are generally reserved for situations in which less potent products have not worked. They should be used with caution, and should only be applied to the areas that are affected with the rash. Using a product in this category for longer than 2 weeks at a time increases the risk of permanent skin damage.
High-potency topical corticosteroids (classes 2 and 3) are best for the trunk, arms, and legs, but should not be used on the face, neck, under the arms, or in the groin area. Using a product in this category for longer than 2 weeks at a time increases the risk of permanent skin damage.
Intermediate-potency topical corticosteroids (classes 4 and 5) can be used in children for up to 1-2 weeks at a time. This type of medication is best for the trunk and extremities. It is safer for use on thin skin, and less effective on thicker skin.
Low-potency topical corticosteroids (classes 6 and 7) can be used on any part of the body, and can be used in children. They are the best choice for the face, uadera~m area, groin, neck, and i ftl Occluded areas such as skin folds.
Cautions and Warnings
Do not use a topical corticosteroid if you are allergic or sensitive to corticosteroids or to any ingredients of the aerosol, cream, gel, lotion, ointment, or solution. Do not use a topical corticosteroid as the sole treatment for bacterial skin infections such as impetigo, viral skin diseases such as herpes, fungal skin infections such as athlete’s foot, or known tuberculosis of the skin. These drugs should not be used in the ear if the eardrum is perforated. Do not use a topical corticosteroid on ulcerated skin, or to treat acne.
Skin problems can become less responsive with time if a product is applied continuously over a long period of time. This can re-
sult in a flare-up of the problem when the medication is stopped.
Using a less potent product may avoid this problem.
Rectal corticosteroid products should not be used if you have any serious bowel condition, including bowel perforation, obstruction, abscess, and systemic fungal infection.
The rectal foam is not expelled after it has been applied and may result in higher drug blood levels than those associated with rectal enema products. The risk of systemic (whole-body) side effects is greater when more of the drug enters the blood. If there is no improvement after 2 or 3 weeks of using a rectal corticosteroid, contact your doctor.
Using a topical corticosteroid around the eyes for prolonged periods may cause cataracts, glaucoma and/or permanent thinning and fragility of skin around the eyes where the corticosteroid is being applied.
Children may be more susceptible to serious systemic side effects from topical corticosteroids, including growth retardation, Cushing’s syndrome, and suppression of natural corticosteroid production, requiring a tapering of the medication, especially if the medications are applied to large areas over long periods. Super-potent topical corticosteroids are not recommended for children.
Possible Side Effects
♦ Most common: burning; itching; irritation; “steroid” acne; skin thinning, tightening, or discoloration; stretch marks; dry cracked skin; bruising; and secondary i0ection. These effects are more likely when the treated area is covered Stith al) occlusive bandage (one that prevents contact with water and air). Side effects are more likely with extended use of high-potency topical corticosteroid products and when the treated area is covered with a bandage that completely prevents skin contact with water and air.
Possible Side Effects (continued)
V Significant amounts of corticosteroids may be absorbed into the bloodstream if large amounts are used for long periods. This can result in systemic effects and may cause serious problems, particularly in people with liver disease. Systemic side effects include lightheadedness, hives, growth suppression, and adrenal suppression.
Drug Interactions None known.
Usual Dose
Adult
Cream, Ointment, Solution, Foam, and Aerosol: Apply a thin film to the skin 2-3 times a day. High- and super-potent products should be applied no more than twice a day, and should be used for short-term treatment, usually 2-3 weeks at a time. Some may have to be applied only once a day.
Rectal Enema: 100 mg nightly for 21 days.
Rectal Foam: 1 applicator’s worth, 1-2 times a day for 2-3 weeks.
Child: Dosages for children should be limited to the lowest possible potency.
Overdosage
Serious adverse effects are unlikely after accidental ingestion. Excessive use of large amounts of topical corticosteroids may cause overdose symptoms and require gradual discontinuation of the drug. Call your local poison control center or a hospital emergency room for more information. ALWAYS bring the prescription bottle or container.
Special Information
To prevent secondary infection, clean the skin before applying the drug. Apply a very thin film and rub in gently—effectiveness depends m contact area, not the thickness of the layer applied.
Do not wash, rub, or put clothing on the area until the medication has dried.
Topical corticosteroids have an additive effect: with continuous use, 1 or 2 applications a day may be as effective as 3 or more. Once the drug begins to take effect, your doctor may recommend reducing the dose to the minimum level needed to control the
condition.
Flurandrenolide tape comes with specific directions for use-, fol-
low them carefully.
If your doctor instructs you to apply plastic wrap or any other occlusive dressing, follow directions carefully. These dressings can increase the penetration of the drug into your skin by as much as 10 times, which may be a crucial element in the medication’s effectiveness. Occlusive dressings should not be used with any of the super-potent topical products.
If you are using one of these products for diaper rash, do not use tight-fitting diapers or plastic pants, which can cause too much drug to be absorbed into the blood.
Your doctor may prescribe a specific form of the product with good reason. Do not change forms without your doctor’s knowledge: a different form may not be as effective.
If you forget to administer a dose, do so 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. Do not administer a double dose.
Special Populations
Pregnancy/Breast-feeding: Large amounts of corticosteroids applied to the skin for long periods of time may increase the risk of birth defects. When your doctor considers any of these drugs crucial, its potential benefits must be carefully weighed against its risks. Do not use any over-the-counter hydrocortisone product for more than a few days without your doctor’s knowledge.
Nursing mothers who must use a topical corticosteroid should consider using infant formula. If you apply a corticosteroid to the nipple area, be sure to completely clean the area prior to nursing. Nursing mothers should never use the highest potency corticosteroids (classes 1, 2 or 3) because of the risk of absorbing large amounts of drug into the system that could find its way into breast milk. Nursing mothers should discuss toqkoa1 corticosteroid use with their doctor befQ(e,applying any product.
Seniors: Seniors are more susceptible to high blood pressure and osteoporosis (a condition characterized by loss of bone mass due to depletion of minerals, especially calcium) associated with large dosages. These effects are unlikely with topical corticosteroids unless a high-potency medication is used over a large area for an extended period.

Brand Name
Cosopt
Generic Ingredients  Dorzolamide + Timolol
Type of Drug
Carbonic anhydrase inhibitor and beta blocker combination.
Prescribed For
Open-angle glaucoma and ocular hypertension.
General Information
Cosopt contains 2 glaucoma drugs that work in different ways. It is intended for people whose glaucoma does not respond to either drug used alone. Small amounts of dorzolamide and timololthe active ingredients in Cosopt–enter the bloodstream.
Cautions and Warnings
Do not use Cosopt if you are allergic or sensitive to any of its ingredients or cannot take sulfa drugs or beta blockers. Cosopt should not be used by people with bronchial asthma, severe chronic obstructive pulmonary disease, slow heart rate or heart block, heart failure, or who are in shock.
People with diabetes or an overactive thyroid should use Cosopt with caution since beta blockers can mask the signs of low blood sugar or hyperthyroidism.
Small amounts of both ingredients enter the bloodstream and can produce the same kinds of systemic (whole-body) reactions associated with larger dosages of either a sulfa drug or beta blocker. Stop using the drug at once and call your doctor if a serious reaction develops.
4lt?18b)ockers may have to be discontinued prior to major surgery because they can affect the heart’s ability to respond normally. Some people taking a beta blocker experience severe reductions in blood flow while undergoing general anesthesia.
Dorzolamide should not be used by people with kidney disease and has not been studied in people with liver disease.
People with a history of severe allergic reactions who take a beta blocker may be at increased risk of experiencing a reaction because the drug blocks part of the body’s natural allergic
response.
Timolol can worsen the muscle weakness that accompanies myasthenia gravis.

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.
Usual Dose
Tablets
Starting dose: 25 mg in divided doses twice a day; maintenance dose    generally, 300-450 mg a day in divided doses. Dosage may be increased gradually to a daily maximum of 900 mg in divided doses if required.
Orally Disintegrating Tablets
Starting dose: 12.5 mg once or twice a day increasing to 300450 mg a day in divided doses by the end of 2 weeks. Dosage may then be increased up to 900 mg a day in divided doses if required.
Overdosage
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
Dosing of narcotic pain medications is highly individualized based on patient tolerance and response to medication.

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.

Sinus cavities are something that most people just don’t know they have. It’s only when they start to

hurt that you find out where they are. ‘There is this terrible throbbing pain above and around my eyes,

and in my cheeks. It’s the most unpleasant feeling, but it’s hard to describe to anyone who hasn’t felt

it,’ says Gina, who suffers from chronic sinusitis (long-term inflammation of the sinus cavities).

There are no figures, but chronic sinusitis seems to be increasingly common.
A sinus cavity has no function, it is just empty space without which our skulls would be much heavier.

In other words, these airy spaces seem to have evolved simply to help us feel more ‘light-headed’. If

you have sinusitis, unfortunately, you feel just the opposite. ‘I had sinusitis for years,’ says Dr

Wellington S. Tichenor, a New York allergist who now specialises in treating chronic sinusitis. ‘I kept

working but felt like I wanted to die.’
Sinus cavities are lined with a membrane which is essentially similar to that lining the nose. It

contains immune cells and can produce mucus when necessary. Most of the time it doesn’t need to produce

much, because relatively few microbes or foreign particles get into the sinus cavities.
Any mucus that is produced should escape from the sinus cavities through narrow drainage channels,

called Ostia, leading to the nose. Unfortunately, the Ostia are very narrow – the diameter of a

pin-head – and U-shaped, making them prone to blockage. And that is not the only problem. These

drainage channels are situated at the top rather than the bottom of the main sinus cavities – this

arrangement was fine for our ancestors who walked on all fours, and therefore did not have to fight

gravity when clearing their sinuses. Sadly for
us, natural selection has not got around to reorganising things yet. It would be a completely hopeless

arrangement if not for the tiny hairs known as cilia, which lie like a carpet across the membranes

lining the sinus cavities. The cilia beat rhythmically. 18 times a second, to waft the mucus upwards to

the top of the sinus cavity.
This is a far-from-perfect system, and it is hardly surprising that it sometimes goes wrong. Chronic

sinusitis can begin in at least three different ways:
• The sinus membranes become inflamed due to an allergic reaction – 28 for likely airborne

allergens.
• The drainage channels from the sinus cavities become blocked due to events in the nose

(infection or allergy) or due to the growth of polyps (non-cancerous jelly-like lumps that can block

the drainage channels). When mucus cannot drain away, it stagnates in the sinus cavities encouraging

infection by bacteria or fungi. These infections cause inflammation.
• A bout of acute sinusitis (see box on p. 31), due to bacterial infection, never really goes

away and the persistent infection causes longterm inflammation. Note that this is unlikely: it is rare

for acute sinusitis not to clear up.
Whether the problem begins through allergy or blockage or infection, once it has begun a vicious circle

can be set up all too easily. Mucus output increases when there is inflammation, blocking the drainage

channels even more, so the sinus cavities become clogged up and increasingly uncomfortable. More mucus

pooling in the sinus cavities perpetuates any existing infections and fosters new ones.
All this infection results in more severe inflammation, causing the membranes which line the sinus

cavities to swell up. Inflammation also makes polyp growth more likely. The cilia may be lost or

severely depleted, and the mucus gets thicker. All this means yet more blockage. To cap it all, there

can be allergic reactions to some of the microbes involved (see right), fuelling the inflammation

further.
The body’s own attempts to clear the sinuses are defeated, and the problem is also very resistant to

medical treatment. This may make depressing reading, if you have chronic sinusitis, but don’t despair.

Understanding the complexities of the problem is a large part of the battle. Chronic sinusitis is not

invincible, if you have a good doctor to help you - that means a doctor who also understands these

complexities.
The symptoms of sinusitis are:
• pain and a sense of swelling or unpleasant fullness around the cheeks, or over and between the

eyes
• earache or headache; pain around the teeth
• reduction in the senses of smell and taste
• sore throat
• coughing, particularly at night
• post-nasal drip (mucus from the back of the nose running into the throat and airways)
• bad-smelling breath
• feverishness
• for some people, severe fatigue, poor concentration and even (but very rarely) psychiatric

symptoms
• irritability, especially in children.
Note that any of these symptoms can be caused in other ways, and even if you have several of them, you

may not necessarily have sinusitis. On the other hand, sinusitis can go unrecognised - to some people

it may seem like nothing more than a lingering cold.
Acute or chronic?
In medical terms, ‘acute’ means short-lived, while ‘chronic’ means long-lasting.
Acute sinusitis — a short, sharp dose of it, lasting less than 3-4 weeks - usually follows on from a

cold. Colds are caused by viruses, but a bacterial infection can follow, and it is the bacteria that

move into the sinus cavities and cause trouble. Some people are far more susceptible than others and

have an attack of sinusitis after every cold.
Chronic sinusitis means symptoms lasting more than three months, according to some authorities, but the

time point is a little arbitrary. This article deals with chronic sinusitis.
If your sinusitis has been going on for between four weeks and three months you will obviously be

asking ‘Is this acute or chronic?’ At this point, no one can say, but you would certainly be wise to

seek some expert medical treatment now, on the basis that it could be the start of chronic sinusitis.

Tackling chronic sinusitis before the problem becomes
entrenched and complex is a good plan.
Allergy and chronic sinusitis
Chronic sinusitis is not necessarily an allergic disease, but it can be connected with allergies (or

other forms of immune sensitivity) in various ways:
• Allergic reactions can occur in the sinuses, usually in conjunction with allergic reactions in

the nose.
• Even if the allergic reaction does not affect the sinuses directly, allergic reactions in the

nose can block the drainage channels from the sinuses, causing an accumulation of mucus there. This may

lead to sinus infections.
• Once sinusitis has begun, infectious fungi (moulds) in the sinuses may provoke allergic

reactions, or other forms of immune sensitivity. This allergy to ‘the enemy within’ fuels more

inflammation and more mucus production. Right now, allergic fungal sinusitis (as it is known) is a

source of heated debate - 32. Allergic reactions to some of the bacteria that are present may also

occur.
• Chronic sinusitis - however caused - can contribute to asthma. Research on children with both

sinusitis and asthma found that 80% no longer needed asthma drugs once their sinusitis had been

treated, and 85% no longer wheezed. The link may be due to post-nasal drip, increased mouth-breathing,

or to a nerve-connection between the sinuses and the airways (the sinobronchial reflex) which can

stimulate airway inflammation. Alternatively, the sinusitis may simply fire up the immune system with

messenger chemicals in the bloodstream, resulting in more powerful responses throughout the body.
• Chronic sinusitis can also be the root cause of long-standing nettle rash (chronic urticaria),

and treating the sinusitis can result in a prompt and remarkable clearance of the skin symptoms.
• Some people who have chronic sinusitis are sensitive to aspirin (see box on p. 28) - a

sensitivity which is also linked with asthma, nasal polyps, rhinitis and chronic urticaria. Avoiding

aspirin and all other aspirin-like drugs (151) may substantially improve the sinusitis.
Diagnosis
Because so many different factors can play a part in chronic sinusitis, diagnosis should, ideally,

consider the problem from several different angles:
• The sinuses are viewed using X-rays and CT scans (computed tomographic scans - they use X-rays

but give a much more precise picture). These reveal how badly swollen the sinus membranes are, which

sinus cavities are blocked, and how much mucus has collected in the sinuses.
• Endoscopy (92) may be used to look inside the sinus cavities. Polyps are best located by this

method.
• Where allergies seem to be part of the picture, the doctor may employ skin-prick tests (91) to

identify allergies to airborne allergens (from house-dust mites, moulds, pets, pollen, cockroaches,

etc.)
• Laboratory tests on samples taken from your sinus cavities will be used to show which bacteria

and/or fungi have set up home there. There may also be a hunt for the immune cells known as eosinophils

(19) or the typical debris which they generate. The presence of large numbers of eosinophils is one

indication of allergic fungal sinusitis (see below).
• Skin testing with fungi (moulds) found growing in the sinus cavities may also be tried if

allergic fungal sinusitis is suspected.
• In severe cases, there may be tests of immune function, to see whether this is depressed in any

way.
• Children may be tested for an inherited disorder affecting the cilia, or for cystic fibrosis -

mild forms may escape detection, and can produce both chronic sinusitis and wheezing.
The enemy within
The biggest controversy in sinusitis research at the moment concerns allergic fungal sinusitis. The

orthodox view of this condition is that:
• It affects a small minority of chronic sinusitis patients -fewer than 10%.
• There is a true IgE-mediated allergic reaction to the fungus (mould) growing in the sinus

cavities. This allergic reaction is detectable with a skin-prick test (91). Immune cells known as

eosinophils (19) are also key players in the inflammatory reaction to the fungus, but it is an

IgE-response to the fungus that draws the eosinophils into the sinuses.
• There is clear evidence of fungal infection in the mem- banes of the sinus cavities.
• There may also be ‘fungus balls’ - a solid mass of fungus inside the sinus cavity. Or there may

be ‘allergic mucin’, a dark sticky mucus containing fragments of the fungus.
A rare complication
In rare cases, the fungi involved in allergic fungal sinusitis can be invasive, spreading from the

sinuses to the surrounding bone. This problem needs prompt and thorough treatment with anti-fungal

drugs.
In 1996, researchers at the Mayo Clinic in Rochester, Minnesota, USA, caused a rumpus by claiming to

have identified a different form of allergic fungal sinusitis which is overlooked by standard

diagnostic techniques, and which affects 96% of patients with chronic sinusitis.
This is a staggering figure - 96% means, in effect, that they are claiming to have found the

fundamental cause of virtually all chronic sinusitis. ‘Up to now, the cause of chronic sinusitis has

not been known. Our studies indicate that, in fact, fungus is the likely cause of nearly all of these

problems,’ states Dr David Sherris, one of the researchers.
According to the Mayo Clinic team:
• The fungi (moulds) are growing in the mucus of the sinus cavities, not generally in the

membrane itself. They are not detected by normal diagnostic methods which tend to ignore the mucus. A

special method of collecting the mucus is required to detect the fungi.
• The immune reaction to the fungi is not usually an IgEmediated reaction, so skin-prick tests

are often negative.
• Finding evidence of unusual numbers of eosinophils is adequate for diagnosis of allergic fungal

sinusitis because the eosinophils are the prime movers in this sensitivity reaction to the fungi, as in

several other diseases (19).
‘We can now begin to treat the cause of the problem instead of the symptoms,’ says Dr Eugene Kern, head

of the research team. There is a lot of scepticism about these claims among other sinusitis

specialists, and so far no new treatment for chronic sinusitis has emerged.
The Mayo Clinic researchers say that they are in the process of developing a drug treatment, but that

it will take several more years before it is generally available. Existing anti-fungal drugs (taken in

capsule form) could not work on this particular form of allergic fungal sinusitis (if it exists)

because the drug does not get into the mucus. Any new treatment would probably involve inserting an

anti-fungal drug directly into the sinus cavities, which is far from easy.
All we can do for now is wait and see what emerges from the ongoing research. The current treatment for

allergic fungal sinusitis involves all the usual methods (see right) with special emphasis on steroids

to calm the inflammation, plus anti-fungal drugs where fungal infection is detectable in the membrane.

In some countries, immunotherapy is also used to reduce the immune reaction to the fungus, but this is

difficult to obtain in Britain (164).
Clearing moulds from your home may help (34). So may reducing the humidity in the house (119), as humid

conditions seem to be linked with allergic fungal sinusitis.
Treatment
Sinusitis can be very hard to treat, particularly if it has been going on for a long time. You need a

really committed attitude if treatment is to be successful.
All these treatments should be given at the same time:
1 Antibiotics for 2-3 weeks minimum (it takes this long because the antibiotic has such trouble getting

into the sinus cavities – if you are offered a shorter course, this suggests that the doctor does not

have enough expertise with chronic sinusitis, so you might be better off with someone else). It must be

the right antibiotic – commonly used ones such as penicillin, tetracycline and erythromycin are

unlikely to work because the bacteria are usually resistant to them.
2 Steroid drops in the nose to combat the inflammation. It is important to put these in correctly, so

that they have maximum effect (144) especially if you have polyps.
3 Irrigating the nose and sinus cavities daily with sterile salt water (saline). Your doctor will show

you how to do this.
4 Tablets that reduce the congestion in the nose.
5 Nose drops that reduce congestion, but for three days only (29).
6 Steam inhalations to loosen the mucus. There are special steam vaporisers on sale (ask at a

pharmacy), but you can just inhale steam from a bowl of boiling water, with a towel over your head to

keep the steam in. Adding eucalyptus oil to the water may help. For a quick-and-easy version, warm up a

damp flannel in the microwave and place it over your nose. Some doctors recommend having a steam

vaporiser beside the bed at night, when nasal blockage is most likely to occur, but if you have

allergies to house-dust mite or moulds this is not a good idea in the long term, as a damp bedroom will

favour both (and could encourage allergic fungal sinusitis).
7 A drug called guaifenesin which thins the mucus is used in some countries but rarely in Britain.

Alpha-methyl-cysteine is another drug that breaks up mucus. It is mainly used in chronic bronchitis but

some doctors also find it valuable in chronic sinusitis. If steam inhalations didn’t work – suggesting
that the mucus is too solid to be shifted – these drugs may be worth trying.
8 Anti-fungal drugs (taken by mouth) if allergic fungal sinusfis is suspected. Sometimes these have a

dramatic effect on chronic sinusitis that has previously resisted treatment.
You may also be given other drugs, such as steroid tablets. The new anti-leukotriene drugs (149) are

also being tried, with some success. As well as being taken by mouth, they can be applied directly to

the nose in an irrigation fluid, and may be helpful for those with nasal polyps.
Problems with nose drops
Nasal drops and washes contain preservatives and other non-drug ingredients. Some of these may act as

irritants – or the pH (acidity or alkalinity) of the preparation might cause problems. If you

experience burning or irritation after inserting drops or irrigating the sinuses, ask your doctor or

pharmacist about trying a different preparation.
Antibiotic resistance
Bacteria are becoming resistant to the effects of antibiotics: it is probably the biggest headache

facing modern medicine.
This is emerging as a particular problem in chronic sinusitis because many patients have been dosed

very regularly with antibiotics. Although most of the bacteria have been killed each time, the fact

that the sinus cavity is so clogged up with mucus, and so badly accessed by the bloodstream anyway,

means there is always some nook or cranny where a few bacteria survive because they have not been

exposed to the full lethal dose of the antibiotic. As you might expect, these survivors tend to be the

‘tough ones’ – those bacteria that are not just well hidden but also the least sensitive to the

antibiotic.
Repeat this process many times, with frequent courses of antibiotics (separated by intervals during

which the hard-to-kill bacteria multiply in numbers) and what happens? Eventually you breed a race of

bacteria that are completely resistant to one or more of the antibiotics taken.
If you ever get to this point with your sinusitis, treatment is going to be extremely difficult. That’s

why it is so important to treat infections really thoroughly, and get rid of them completely. Expert

medical help is essential for this treatment campaign.
Too many people with chronic sinusitis are careless about taking their antibiotics regularly, or feel

ambivalent about them and stop the course before it’s complete, or don’t see the doctor again when the

tablets are used up. This is courting disaster.
Don’t start antibiotic treatment for chronic sinusitis until you are sure you can see it through. If

you have doubts about taking antibiotics, try all the other treatments and self-help measures first.

They may be sufficient, especially if you find you have an allergy underlying the chronic sinusitis and

can tackle this successfully.
Should there be no improvement, you could then go on to the antibiotic programme: delaying this

treatment for a few months will do no harm. What is hazardous is starting the antibiotic programme and

then stopping, or not taking the drugs consistently.
Antihistamines may be prescribed to treat any allergic reactions, but some specialists feel that they

can also aggravate the problems. In their experience, antihistamines dry out the mucus so that it

sticks to the walls of the sinus cavities, rather than being ushered out by the cilia. Drying out the

mucus may make you feel better initially, by reducing the pressure inside the sinus cavities, but it

makes matters worse in the long run.
Anti-chollnergic drugs (156) are sometimes prescribed for chronic sinusitis, but they too can dry up

the mucus and should be used cautiously.
After three weeks, if the sinusitis has not improved substantially, a different antibiotic is given. If

there are any bacteria resistant to the first antibiotic infesting your sinus cavities, the new

antibiotic is intended to kill them off.
Should you still have sinusitis after another three weeks, you will be given yet another antibiotic.

Changing the antibiotic, and taking prolonged courses, is the best way of exterminating the bacteria

completely, which prevents the development of antibiotic-resistant bacteria (see box at left).
It is crucial that you always see the doctor promptly at the end of each course, so that there is no

gap between the courses – do not give the bacteria any opportunity to build up their numbers again. The

last antibiotic treatment should continue for at least a week after symptoms clear up.
Dealing with allergic reactions is also important:
• If you cannot get allergy tests, try to work out for yourself if an allergen is playing a part.

Ask yourself if there were any changes in your life before the sinusitis began, such as getting a new

pet, moving house, increased exposure to moulds or house-dust mite, or starting a new job with exposure

to allergens. When thinking about this, remember that allergies to newly encountered allergens do not

develop immediately – it may take up to two years. Try avoiding the allergen concerned and seeing if

you improve.
• Should you discover that an allergen is at the root of the problem, but have difficulty

reducing your exposure to the offending item, try to obtain immunotherapy (164) or another form of

desensitisation treatment (210).
• If you suspect allergic fungal sinusitis (32), it is well worth eliminating any mould growth in

your home (120). One research study showed that the moulds growing in a patient’s sinus cavities were

often the same as those growing in the patient’s house. It is possible that, by inhaling the mould

spores from moulds in their houses, sinusitis sufferers are continually reinfecting their sinuses.
Various other self-help measures can be valuable during this medical treatment:
• Reduce your exposure to cigarette smoke (including other people’s) to an absolute minimum.

Cigarette smoke acts as an irritant to the nose and sinuses, but, more importantly, it paralyses the

cilia, preventing them from shifting mucus out of the sinus cavities.
• Avoid breathing other irritants, especially ozone (130). Think about the chemicals you use both

at work and at home – could any of these be irritants that are aggravating your sinusitis?
• Don’t drink too much alcohol – it dries out the sinus membranes and makes matters worse.
• Drink plenty of water, to keep your mucus from becoming too dry and therefore hard to shift.
• Try to breathe through your nose as much as possible. The amount of oxygen in your sinus

cavities drops drastically if you breathe through your mouth, and the low oxygen level probably fosters

the growth of certain bacteria. Devices, such as nose clips, that help keep the nose open at night may

be worth trying.
• Spicy food can help to clear nasal and sinus congestion, so try eating chilli or hot curry

regularly.
• Some people find that garlic helps – either eaten or sniffed.
• If you suspect that your sinusitis might be related to food sensitivity (68) consider trying an

elimination diet to identify the culprit food.
• Observe your reactions immediately after eating – some foods, such as yeast and red wine, can

cause an immediate swelling of the nasal membranes in certain people. So can sulphite food additives.

Avoid such items if you are affected.
• Treating gastro-oesophageal reflux (acid regurgitation from the stomach after meals) can

improve sinusitis.
• See an osteopath. By gently manipulating parts of your face, a good osteopath may be able to

improve the drainage from the sinus cavities.
• Some patients experience good effects from acupuncture although there are no observable changes

on CT scans. Other alternative therapies, such as homeopathy or Chinese herbal medicines, have not been

investigated scientifically, but some patients report good results.
Prolonged courses of antibiotics destroy many of the beneficial bacteria in the intestine, and may

cause long-term bowel problems. It makes sense to take a bacterial replacer (205).
Surgery for sinusitis
Chronic sinusitis sufferers may be offered surgery to remove polyps, or to correct anatomical problems

such as a deviated septum (the central division of the nose).
These operations can be very useful, but if you have asthma try all other options first, because

surgery to the nose can sometimes make asthma much worse.
Surgery on the sinus cavities themselves is also a possibility, when sinusitis does not respond to

medical treatment. The operation enlarges the natural drainage channels, so that mucus drains away more

easily. This rarely cures chronic sinusitis completely, but it usually makes it much easier to manage.

Once the drainage channels are larger, antibiotics can be put directly into the sinus cavities, for

example, avoiding the need for antibiotic tablets.
Don’t agree to surgery unless other forms of treatment, such as allergen avoidance or immunotherapy,

have been tried to the full. Patients for whom surgery seemed to be the only answer have sometimes

found they did not need an operation once their allergies were treated.
If you decide on having an operation, make sure your surgeon has a proven track-record with this type

of surgery. Don’t be afraid to ask searching questions about how many operations of this kind the

surgeon has done, how many he or she carries out per year, and the complication rates (how often things

go wrong). It’s a delicate job, and you want a real expert.

`When I first arrived in Charlottesville in 1982, the senior allergist said “I’ve got to warn you that here in Virginia we have patients who have very severe fungal infection of their feet, and they also have urticaria. If you treat their feet, their urticaria gets better.”‘ Professor Tom Platts-Mills of the University of Virginia in Charlottesville is recalling how his innovative studies of fungal infections and allergy began. That surprising observation about athlete’s foot (a fungal infection) and urticaria (nettle rash) was made by his predecessor, Professor John Guerrant,
‘I followed his advice,’ Platts-Mills continues, ‘and found he was right. Then I started noticing asthmatics in our allergy clinic who also had fungal infections of their feet. They were mostly men with severe adult-onset asthma. We gave them skin-prick tests with the fungus Trichophyton and these were positive – showing they had an allergic reaction to it. So we tried treating them with anti-fungal drugs and the asthma got much better.’
This discovery is not an isolated instance. Research over the last decade or so has revealed that allergic reactions to long-standing infections (chronic infection is the medical term) are far more common than anyone expected. Infections by fungi are frequent offenders.
An infection becomes chronic because, although the immune system tries to rout the infectious agent, it never succeeds. Making IgE may be part of that futile defensive effort. Once the immune system starts making IgE against the allergens produced by the infectious microbe, new symptoms may begin, or existing allergic symptoms may get much worse. The link between the infection and the allergy is far from obvious, however. Both the allergens and the IgE can be carried in the
Fungal infections
‘Fungus’ means everything from an edible mushroom or a huge bracket fungus to the specks of mould on stale bread or a shower curtain. Fungal infections are caused, not by mushroom-like fungi, but by inconspicuous mould-like forms, or by yeasts (which are single-celled fungi).
Once they are flourishing, some fungal infections may be seen as whitish or creamy-coloured patches. But at an earlier stage, the fungi are so small that they cannot be seen without a microscope. They spread as invisibly as bacteria or viruses.
Some infectious fungi can exist in two different forms – a mycelial form (long thin strands, as in a mould) or a yeast form (single cells).
bloodstream, so the symptoms may be somewhere else in the body, far away from the site of infection.
If the symptoms of the infection itself are relatively mild, they may not receive medical attention. Infection-plus-allergy often explains severe long-term allergic problems for which no cause could previously be found. This is the kind of case that gets labelled as ‘intrinsic’ or ‘endogenous’, because all the allergy tests have proved negative. Most patients in this category have had years of simply being treated with steroids (often at high doses) to suppress the symptoms.
Sometimes the infection-plus-allergy is part of a larger picture, with other allergens or irritants also contributing to the symptoms, but with no stunning improvements when they are avoided because the allergic stimulus from the infection remains.
The links between allergy and fungal infections – all those that have been discovered so far – are described below. In such cases, anti-fungal drugs, taken by mouth, usually in capsule form, could be of value. However, they must be taken for an adequate length of time, normally several months.
Bear in mind that, with the possible exception of chronic sinusitis, an allergic reaction to fungal infection is a relatively uncommon cause of symptoms. It is important that, with the help of your doctor, you start with the more likely suspects such as airborne or contact allergens. These are described in detail, for each allergic disease, in the relevant sections of Chapter 2.
Asthma
the common causes and usual treatment of asthma.
Trichophyton – the fungus that causes athlete’s foot – can provoke allergic reactions that contribute to asthma, as already described. This fungus may also infect other parts of the body. Trichophyton diseases have names that begin with tinea (athlete’s foot, for example, is tinea pedis). Other terms you may come across are intertrigo (an itchy rash which develops in skin folds) and onychomycosis (also called `ringworm of the nails’ or tinea unguinum). The research on the link with asthma was published in a respected medical journal, The Lancet, but has been widely ignored, so if you think you have this problem, you may have to be quite persistent with your doctor. Very thorough treatment with anti-fungal drugs (swallowed in capsule form) is required.
Chronic urticaria
many possible causes of chronic urticaria.
Trichophyton infections in any part of the body (see above) can provoke allergies, producing chronic urticarla. A great variety of other infections, including fungal, viral and chronic bacterial
infections, can be the root of the problem in chronic urticaria . However, this may not be an allergic reaction. It could be a direct effect of the infection, provoking the immune system in such a way that it triggers mast cells by itself, without IgE.
Chronic sinusitis
 the causes and treatment of chronic sinusitis.
Long-standing (chronic) sinusitis may be due to a fungal infection with a subsequent allergy. This is now called allergic fungal sinusitis. Some doctors believe that a sensitivity reaction to fungal infection (not necessarily an allergic reaction) could account for 96% of chronic sinusitis. However this is widely disputed .
Atopic eczema (atopic dermatitis)
the causes and treatment of atopic eczema.
The Trichophyton fungus can infect eczematous skin, though this is far less common than infection by Staphylococcus aureus (see below). Among patients infected by it, there can be an allergic reaction to Trichophyton which then makes the eczema worse.
There can also be an IgE reaction to a yeast, Pityrosporum ovale (also called Malassezia ovalis), in atopic eczema. This yeast is a commensal – i.e. a natural, and normally harmless, inhabitant of healthy skin. The inflammation of eczema makes the immune system far more tetchy so that it reacts allergically to this yeast, an innocent bystander which it normally disregards.
Candida  can also provoke an allergic reaction in eczematous skin. This is a more complex story, because while Candida is a commensal in the gut, it does not normally live on the skin. However, it may flourish in the disturbed skin of eczema patients.
Those with atopic eczema may also develop an allergic reaction to toxins from Staphylococcus aureus, a bacterium that often infects skin which is inflamed by eczema and damaged by scratching. Antibiotics are needed to treat the infection .
Seborrheic dermatitis
Not so long ago, this disease – which causes a red, scaly rash on the forehead, nose and cheeks, and sometimes on the chest –was labelled ’cause unknown’. Now most doctors believe that the yeast Pityrosporum ovale could well have a role in causing it. This yeast is part of the normal skin flora (see above), but it is found in greater numbers on the skin of seborrheic dermatitis patients. As well as overgrowth of the yeast, there is an immune reaction against it, usually involving the antibody known as IgG, rather than Fungi in the lungs
One form of infection-plus-allergy has been well recognised for many years - allergic bronchopulmonary aspergillosis, often shortened to aspergillosis.
The problem starts with the fungus Aspergillus fumigates, a ubiquitous mould that is found in special abundance in damp straw, compost heaps, bird cages and any decomposing material. Its spores are everywhere, and most immune systems quickly defeat them, but in some people, especially those with asthma, the spores begin to grow in the lungs. The fungus is found in the lung mucus, but does not actually invade the lungs. However, an allergic reation then occurs to the fungus.
This disease often goes together with asthma, or can be mistaken for asthma. There are three clues that point to aspergillosis:
• rubbery plugs of phlegm, either golden-
brown or green in colour
• fever whenever the asthma is severe
• worsening symptoms despite treatment.
Allergic bronchopulmonary aspergillosis is treated with steroids to control the allergic reaction, and physiotherapy to clear the mucus from the lungs.
Anti-fungal drugs have not proved very effective in the past. There are some newer anti-fungal drugs that may well be more useful, such as itraconazole and terbinafine. These are not widely used for aspergillosis at present, except in patients who also have cystic fibrosis or an immune deficiency. Because there has been no large-scale trial of these drugs, they are not usually given to people who simply have aspergillosis. However, they are sometimes prescribed for people who are unable to take steroids, or are not responding to steroid treatment. Anti-fungal drugs may become more widely used in the next few years, so it is worth discussing the possibility of this treatment with your doctor.
the allergy antibody IgE. Only about 12% of people who suffer from seborrheic dermatitis make IgE against the yeast.
One problem with seborrheic dermatitis is that, while it may improve with anti-fungal treatment, it usually comes back when the treatment stops. Doctors have therefore been looking for ways of keeping seborrheic dermatitis at bay after a successful course of anti-fungal treatment. One method that seems to work is to use a good anti-dandruff shampoo, in place of soap, to wash your skin once a week.
A medical earthquake
The recent discoveries about infection-plus-allergy have not posed any serious challenge to conventional thinking about allergy, because a disease of just this kind - aspergillosis (see box at left) - was already well known. A far more fundamental shake-up of traditional ideas about allergy and sensitivity has been necessitated by new research into atopic eczema. It is little short of an earthquake in the basic concepts of allergy and sensitivity.
To understand the extent of this earthquake, you need to know about the time-honoured system for classifying hypersensitivity reactions, which recognises four distinct types:
• Type I hypersensitivity — the IgE-mediated allergies  such as hayfever.
• Type II hypersensitivity - irrelevant to allergy, these antibody reactions mainly occur after transplant surgery, if the transplanted organ is rejected.
• Type III hypersensitivity - caused by a massive overload of antibodies and antigen in the blood. It is a feature of certain infections and autoimmune diseases, and can also occur in allergic reactions, though this is rare (13).
• Type IV hypersensitivity - the odd man out, because antibodies are not involved, or are not of central importance. Immune cells that can launch a direct attack are the movers and shakers here. These attacking-cells are sensitised for a particular antigen, such as dust mite or lanolin. Type IV hypersensitivity is a very slow reaction. Generally speaking, 48 hours pass, after an encounter with the offending substance, before the symptoms appear. The most common form of Type IV hypersensitivity is contact dermatitis (54).
Mystery has always surrounded atopic eczema. Although it crops up in the same atopic families that suffer from hayfever and asthma, and high levels of IgE in the bloodstream are typical of the disease, the actual role played by allergies in causing the symptoms is far from obvious.
The results of skin-prick tests - the standard test for an IgEmediated reaction - are puzzling. Patients tend to give a lot of positive results, many of which don’t mean much - the substances concerned do not provoke actual symptoms. On the other hand, skin-prick tests are often negative for substances that clearly do cause symptoms in challenge tests. Many children who regularly get eczema when they drink cow’s milk, for example, give a negative skin-prick test to milk. This conundrum has puzzled allergists for decades.
New discoveries about eczema do not entirely solve the puzzle, but they do go some way towards an answer, by revealing an immune response that cuts across the traditional categories. The most surprising fact is that even where skin-prick tests are positive and milk-specific IgE is involved in milk-induced eczema, this is not necessarily a standard IgE-mediated allergy.
While IgE antibodies may be involved, they are not necessarily teamed up with mast cells, their usual partners in crime (see box on p. 12). Instead, the IgE molecules are attached to special skin cells called Langerhans cells and dendritic cells. These have the role of picking up the antigen and showing or ‘presenting’ it to attacking-cells in the skin (a task called antigen presentation which is the ‘go’ signal that starts off all immune reactions).
The involvement of these attacking-cells, which are sensitised for a particular antigen, was a big surprise when first discovered. It makes this resemble a Type IV hypersensitivity reaction rather than a Type I.
IgE is not essential here, it seems — some patients do not have IgE for the substance that triggers their atopic eczema — but when Langerhans cells and dendritic cells are associated with IgE they do become far more zealous. This excitement is communicated to the attacking-cells, which mount a more powerful attack.
It looks as if what really matters in atopic eczema is the presence of antigen-specific attacking-cells in the skin, plus the heightened activity of the Langerhans cells and dendritic cells. If the individual has IgE for the antigen, it can play a part, but it is not essential.
In other words, this reaction cuts across two different categories of immune response — Type I and Type IV. (However, the kind of antigens that provoke the reaction are typical of IgEmediated allergy, rather than the kind of antigens that provoke contact dermatitis.) This has been exploited in a new and more sensitive set of diagnostic tests for food-induced atopic eczema (69).
Why atopic eczema is a feature of atopic families is the crucial question that remains unanswered. One factor may be that high levels of IgE in the bloodstream (not IgE for a particular allergen, but total IgE) make the whole immune system more excitable and prone to over-react. The next few years will no doubt solve this part of the puzzle too.
Peace-keepers or aggressors?
`It is bad enough having a child on an ultra-strict diet — Tim can’t have even a trace of cow’s milk or else he becomes violently ill. What makes it worse is when people — teachers, for example —ask what’s wrong. I take a deep breath and say “eosinophilic oesophagitis” then watch their eyes roll in disbelief.’
Tim’s disease is caused by a particular type of immune cell called an eosinophil. In the right circumstances, eosinophils can be valuable — like IgE and mast cells, they are geared to destroying parasitic worms . They produce some very toxic substances to kill these invaders, and it is the toxins that cause serious symptoms for Tim and others like him.
Any disease with ‘eosinophilic’ in the name involves vast numbers of eosinophils converging on some unfortunate part of the body. The stimulus that attracts them often remains unknown but once there, the toxins they generate cause inflammation (140) of a particularly violent kind.
It is only in recent years that doctors have begun to distinguish between patients such as Tim and children with classical food allergy, and to understand the cause of Tim’s symptoms. Several different forms of eosinophilic food sensitivity are now recognised (72). The exact relationship with IgE-mediated allergy remains a puzzle, because some sufferers make IgE to the culprit food but others do not.
That is not all — the eosinophil is finally coming out of the shadows and being recognised as an important agent in classical allergic diseases as well.
The fact that eosinophils appeared during the aftermath of an allergic reaction had long been known, but their role was misunderstood. What confused researchers was that eosinophils can break down histamine, the substance that kick-starts allergic symptoms. This ability gave eosinophils the appearance of peacekeeping troops, coming in at the close of battle to restore order. In fact, eosinophils are major aggressors — they do a whole lot of other things besides breaking down histamine, most of them pro-inflammatory. They can release toxins, just as they do in eosinophilic diseases, and they attract other inflammatory cells into the area. In short, eosinophils play a big part in keeping allergic reactions going once the initial burst of activity is over. This `Late Phase Reaction’ is enormously important .
