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.

Type Q( UTUg  Narcotic.
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

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.

•    Clonazepam may decrease the effect of levodopa + carbidopa.
Food Interactions
Clonazepam is best taken on an empty stomach but may be taken with food if it upsets your stomach.
Usual Dose
Clonazepam is available in either tablets or orally disintegrating tablets, called wafers. Wafers should not be opened until immediately before the dose is to be taken. Do not push the wafer through the foil. Use dry hands to remove the wafer. The wafer will disintegrate quickly in saliva.
Seizures
Adult and Child (age 10 and over): starting dose    0.5 mg 3 times a day. The dose is increased by 0.5-1 mg every 3 days until seizures are controlled or side effects develop. The maximum daily dose is 20 mg.
Panic attacks
Adult and Child (age 10 and over): starting dose-0.25 mg twice daily. The dose is increased to 1 mg a day after 3 days. Most people do not require a higher dose.
Child (under age 10 or below 66 Ms.): starting dose-0.0220.066 mg per lb. of body weight a day in divided doses. Dosage can be increased gradually to a daily dose of 0.22-0.44 mg per lb. of body weight.
Other uses for clonazepam involve doses from 0.5-16 mg a day, depending on the condition and its severity. Clonazepam dosage must be reduced in people with impaired kidney function.
Overdosage
Overdose may cause confusion, coma, poor reflexes, sleepiness, low blood pressure, labored breathing, and other depressive effects. If the overdose is discovered within a few minutes and the victim is still conscious, it may be helpful to induce vomiting with ipecac syrup—available at any pharmacy. Overdose victims must be taken to a hospital emergency room. ALWAYS bring the prescription bottle or contai”iaT.
Special Information
Clonazepam may interfere with your ability to drive or perform other complex tasks because it can cause drowsiness and difficulty in concentrating.
Your doctor should perform periodic blood counts and liver function tests while you are taking this drug to check for possible
side effects.
Do not suddenly stop taking clonazepam—severe seizures may result. The dosage must be discontinued gradually by your doctor.
If you miss a dose by 1 hour or less, take it right away. Otherwise, skip the dose you forgot and go back to your regular schedule. Do not take a double dose.
Carry identification or wear a bracelet indicating that you have a seizure disorder for which you take clonazepam.
Special Populations
Pregnancy/Breast-feeding: Clonazepam crosses into the fetal circulation and can affect the fetus. Women who are or might be pregnant should avoid it. When the drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
Some reports suggest a strong link between anticonvulsant drugs and birth defects, though most of the information pertains to phenytoin and phenobarbital, not clonazepam. It is also possible that the epileptic condition itself or genetic factors common to people with seizure disorders may figure in the higher incidence of birth defects.
Clonazepam may pass into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors, especially those with liver or kidney disease, are more sensitive to the effects of this drug—especially dizziness and drowsiness—and may require smaller doses.

Cefprozil Cefzil
Ceffibuten Cedax
Cefuroxime Axetil 90 Ceftin
Generic Ingredient: Cephalexin 91 Panixine Disperdose    Keflex
Prescribed For  Bacterial infections.
General Information
These antibiotics are related to cephalosporin C, which is similar to penicillin and is isolated from the Cephalosporium acremonium fungus. Of the more than 20 different antibiotic drugs derived from cephalosporin C, only those that are taken by mouth are included in The Pill Book. Most common infections can be treated with these antibiotics, but they are not interchangeable. Your doctor must select the appropriate antibiotic for a particular infection.
Cautions and Warnings
Do not take cephalosporin antibiotics if you are allergic or sensitive to any of their ingredients. Up to 15% of people allergic to penicillin may also be allergic to cephalosporins. The most common cephalosporin allergic reaction is a hive-like rash condition with redness over large aceas 0 the body. Other sensitivity reac161011S Include general rash, fever, and joint aches or pain. Such reactions generally begin after a few days of taking the antibiotic and resolve within a few days after the antibiotic is stopped.
Prolonged or repeated use of a cephalosporin may lead to a secondary infection not susceptible to the antibiotic.
Occasionally, people taking a cephalosporin develop colitis. Call your doctor if you develop severe diarrhea while taking one of these drugs.
People with poor kidney function may require less medicine to treat their infections. Rarely, people taking a cephalosporin have had a seizure, especially those with kidney disease whose dose was not reduced.
Some injectable cephalosporins have caused blood-clotting problems. This has not occurred in people taking an oral drug.
Rarely, severe anemia occurs in people taking cephalosporin antibiotics. Report any signs of anemia (such as pale skin color, weakness, tiredness, difficulty breathing, and abnormal heart rhythms) to your doctor.
Cefprozil oral suspension contains phenylalanine and cannot be taken by people with phenylketonuria (PKU disease).
Possible Side Effects
Most side effects are mild.
✓    Most common: diarrhea, headache, abdominal pain, constipation, gas, upset stomach, nausea, vomiting, itching, and rash.
✓    Less common: dizziness, tiredness, weakness, tingling in the hands or feet, confusion, appetite loss, changes in taste perception, and genital and anal itching. Colitis may develop.
Cefaclor may cause serum sickness (symptoms include fever, joint pain, and rash). cephalosporins may cause changes in blood cells, kidney problems, liver inflammation, and jaundice, but these side effects are rarely a problem with oral cephalosporins.
Drug Interactions
•    Antacids can reduce the amounts of cefaclor, cefdinir, cefditoren pivoxil, and cefpodoxime proxetil in the blood. Do not take antacids within 2 hours of these antibiotics.
•    Cimetidine, famotidine, ranitidine, or nizatidine can reduce the effectiveness of cefpodoxime proxetil, cefditoren pivoxil, and cefuroxime axetil—do not combine these drugs.
•    Iron and iron-fortified foods may interfere with the absorption of cefdinir. Separate your iron dose from the antibiotic by at least 2 hours. Iron-fortified infant formula does not have this effect.
•    Probenecid may increase blood levels of some cephalosporins.
•    Potent (loop-type) diuretics can lead to kidney damage if mixed with a cephalosporin antibiotic.
Food  Interactions
Generally, cephalosporins may be taken with food or milk if they upset your stomach. Cefditoren pivoxil should be taken with a meal. Food increases the absorption of cefpodoxime proxetil and cefuroxime axetil.
Usual Dose
Ceftibuten
Adult and Child (age 12 and over): 400 mg once a day for 10 days. Child: 4 mg per lb. of body weight, up to 400 mg, once a day.
Cefuroxime Axetil
Adult and Child (age 13 and over): 250-1000 mg a day in 1-2 doses.
Child (age 3 months-12 years): tablets-125-250 mg every
12 hours. Liquid-9-13 mg per lb. of body weight every 12 hours.
Cephalexin
Adult: 1000-4000 mg a day in divided doses, usually 250 mg every 6 hours, or 500 mg every 12 hours.
Child: 11-23 mg per lb. of body weight a day in divided doses. The dose may be increased to 46 mg per lb. of body weight for middle-ear infections.
Overdosage
Common symptoms of overdose are nausea, vomiting, and upset stomach. These can often be treated with milk or an antacid. Cephalosporin overdoses are generally not serious; contact a hospital emergency room or local poison control center for more information. If you seek treatment, ALWAYS bring the prescription bottle or container.
Special Information
Call your doctor if you develop severe abdominal cramps or diarrhea. Stop taking this drug and immediately call your doctor if you experience fever, chest tightness, breathing difficulties, redness, muscle aches, or swelling.
You must take the full course of treatment prescribed—even if you feel better in 2 or 3 days—to obtain the maximum benefit from any antibiotic.
Proper diagnosis is key to the effectiveness of an antibiotic: Do not take any antibiotic without consulting your doctor.
You should be aware that all cephalosporins may cause false results for certain urine tests for sugar. Cefuroxime may cause false results for blood sugar. Diabetics taking cephradine should not change their diet or diabetes medication without consulting their doctor.
If you miss a dose that you take once a day, take it as soon as you remember. If it is almost time for your next dose, take the dose you forgot right away and your next one 10-12 hours later. Then go back to your regular schedule. If you take the medication twice a day, take the dose you forgot right away and the next dose 5-6 hours later. Then go back to your regular schedule. If you take the medication 3 or more times a day, take the dose you missed right away and your next dose 2-4 hours later. Then go back to your regular schedule.
Most cephalosporin liquids must be kept in the refrigerator to maintain their strength. Only cefixime liquid does not require refrigeration. All of the liquid cephalosporins have a very limited shelf life. Do not keep any of these liquids beyond the 10 days-2 weeks specified on the label. Follow your pharmacist’s storage instructions.
Special Populations
Pregnancy/Breast-feeding: These drugs are considered relatively safe during pregnancy, though small amounts pass into the fetus. Little information is available about the newer members of the group. Also, cephalosporins pass more quickly out of the bodies of pregnant women. cephalosporins should only be used during pregnancy after carefully weighing their potential benefits against their risks.
Small amounts of most cephalosporin antibiotics pass into breast milk. Nursing mothers who must take a cephalosporin should use infant formula.
Seniors: Seniors may require a lower dosage if they have reduced kidney function.

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.

Notes on dosage
In this dictionary of drugs, the doses, unless otherwise stated, are average daily doses for adults, and are normally given as divided doses at suitable intervals. An indication is given of those few drugs that are taken as a single daily dose, or where
the dose is based on the surface area of the body expressed as square metres (ml).
When a dose range is indicated, a small initial dose is often followed by gradually increasing doses according to need and response, but with long-acting drugs care must be taken to avoid excessive dosage, as such drugs may then accumulate in the body and have toxic side-effects. It should be noted that the side-effects of a drug may prevent the administration of an optimum therapeutic dose, and a recommended dose is often a compromise between activity and toxicity. The gap is sometimes referred to as the ‘therapeutic window’, and the wider the gap the safer the drug.
Dosage is also influenced by the route of administration, as oral doses are normally larger than those given by intramuscular injection, and the latter are in turn larger than those given intravenously. The weight, age and sex of a patient may also have to be taken into account when assessing dosage. Renal and hepatic
-impairment may require an adjustment of dose, whereas if tolerance to a drug
develops, a larger dose may be required to evoke an adequate response. Dosage
also requires particular care during pregnancy if toxic effects on the fetus are to be avoided and, ideally, no drug should be given in pregnancy unless the need outweighs the risks.
Doses for infants also present problems. Their drug-detoxifying enzyme
systems and renal excretory capabilities are not fully developed although,
paradoxically, they have higher metabolic rates than adults, and so may sometimes require an apparently relatively high dose of a drug.

Doses for the elderly also frequently require modification, as their reduced renal efficiency may cause accumulation of the drug and increase susceptibility to toxic effects, unless reduced doses are given. Elderly patients are, in any case, more susceptible to nephrotic drugs generally. Hepatic disease may also increase drug toxicity as liver enzymes play a major part in drug metabolism, and severe liver disease may give rise to a drug toxicity that might not otherwise occur. Hyperlipidaemic drugs, fusidic acid and some antifungal agents of the ketoconazole type are examples of drugs best avoided in hepatic disease. Multiple therapy may also lead to an increased and not always appreciated incidence of drug toxicity. For further information on these important aspects of drug dosage, a book for nurses on drugs and pharmacology should be consulted.

Controlled drugs
Drugs likely to cause dependence and misuse are referred to as ‘controlled drugs’ (CDs), as they are subject to the strict prescription requirements of the Misuse of Drugs Act, 1971, and are distinguished in this book by a dagger t. They include opium, morphine, heroin (diamorphine), pethidine and other synthetic, potent analgesics/narcotics, dihydrocodeine injection, barbiturates (except intravenous anaesthetics) and amphetamines. Controlled drugs can be supplied only on receipt of a hand-written prescription from the prescriber, giving full details of the patient, the drug, the form and strength of the prescription to be dispensed, and the total amount to be supplied expressed in both words and figures. Certain weak preparations of some controlled drugs, such as Kaolin and Morphine Mixture for diarrhoea, with which misuse is unlikely, are exempt from control, and can be obtained without prescription.

Atopic eczema
A Greek word meaning ‘to boil over’ or ‘to erupt’ is the source of the medical term ‘eczema’. It refers, of course, to the way in which the skin erupts into a rash, but it could equally well describe the eruption of controversy around this disease. No other allergic disease is quite such a cauldron of dissent - indeed, even the question of whether it is an allergic disease remains unresolved. These controversies directly affect the treatment of atopic eczema, so it is useful to understand them if you or your child have eczema.
The disagreement begins with the question of what causes atopic eczema.
Let’s start with the one point that everyone agrees on: dry skin plays a fundamental role. Those with atopic eczema have dry skin, not just in the eczematous areas, but in other parts as well, sometimes all over the body. The skin cells are less efficient than normal skin cells at retaining water.
Everyone would also agree that there is inflammation of the skin – a reaction that is produced by the immune system. But when it comes to the question of what starts off the inflammation there are huge differences of opinion among specialists treating atopic eczema – these specialists include dermatologists, allergists and paediatricians.
Since people with atopic eczema are atopic (allergy-prone), and most have
huge amounts of the allergy antibody, IgE, going round in their blood, it might
seem plausible that an allergic reaction to some external item kicks off the
inflammation. And when skin-prick tests (see p. 91) to common allergens such
as house-dust mite are tried, there are usually a large number of positive results.
But many of these turn out to be false positives – when tested more directly,
the allergen concerned does not actually play a part in causing the skin symptoms.
This has led some specialists working with eczema, mainly dermatologists, to
What the words mean
Eczema is not a disease in itself. The word refers to a certain type of reddish rash — a rash which can be caused in a variety of ways. The type of eczema that affects people of an allergic disposition (atopics), is called either atopic eczema or atopic dermatitis.
The word dermatitis just means inflammation of the skin. Most doctors consider it to be synonymous with eczema, but some give it a slightly broader meaning.
believe that allergic reactions play little part in either initiating or perpetuating atopic eczema. In their view, the basic cause of atopic eczema is dry skin and a generally overwrought immune system, not specific allergic reactions.
To some of these doctors, positive skin-prick tests are all false positives in atopic eczema – that is, irrelevant to the disease process. A positive skin-test result, in their opinion, simply indicates that the skin of atopic eczema sufferers is in a highly sensitive state, not that the allergen concerned plays any causative role.
Allergists tend to take a different view of this, as you might expect. And recent research shows that they are correct – allergens often do play a significant part in provoking atopic eczema.
Research using direct challenge tests (see p. 90) has identified some of the things that could provoke such sensitivity reactions:
• house-dust mites, pollen or moulds
• cats, dogs, rabbits and other furry pets
• cow’s milk or other food – a prime suspect in babies and young children (see p. 68). The response to food is usually delayed, occurring some hours after the item is consumed.
With mite, pollen and pet allergens, the eczema symptoms can be provoked either by allergens falling on the skin, or by direct contact (e.g. mite allergens in the bed, skin contact with pets, or lying on grass for those with grass-pollen allergy).
The rash tends to occur on skin not covered by clothes, as you would expect. But it can sometimes occur only on particular exposed areas – usually the most sensitive areas of skin. For example, there are people who react to house-dust mite but have eczema on the eyelids only.
Additionally, experiments show that even when an airborne allergen is only inhaled it can sometimes provoke eczema symptoms. The allergen probably reaches the skin in the bloodstream. (Alternatively, it might provoke an immune reaction in the airways which generates chemical messages of the kind that promote inflammation – these then reach the skin in the blood.) This means that the skin reaction could occur anywhere on the body, not just on exposed skin.
In the case of food, the molecules of food that cause the trouble are probably being absorbed from the stomach without being completely broken down. They then reach the skin via the blood to provoke a reaction there. (Or, again, it could be an inflammatory messenger chemical travelling from the gut to the skin in the blood.)
When food gets directly onto the skin – which it frequently does with small children, of course – it can provoke a reaction that way too. This may be a slow eczema-causing reaction, or a much faster reaction known as contact urticaria (see pp. 50-51). Reacting to food with contact urticaria is quite common in children with atopic eczema – but the same food doesn’t necessarily provoke atopic eczema when it is eaten. (However, eating these foods can sometimes trigger anaphylaxis – see pp. 58-9. They should therefore be treated with great caution.)
At the same time as all this research – which shows for sure that allergens play a part in atopic eczema – others have been asking what actually happens when skin reacts to an allergen. Their studies have turned the accepted understanding of allergies upside-down. They show that when something like egg or pollen provokes atopic eczema, what is occurring isn’t necessarily an allergic reaction of the usual sort, with IgE and mast cells (see
box on p.12). Instead, other immune cells are causing the trouble. Sometimes IgE is involved, but without mast cells. Sometimes neither is involved. These revolutionary discoveries are described in more detail on pp. 18-19. One interesting realisation from this research is that in different eczema sufferers, different immune reactions may be producing the rash – even if they are reacting to the same allergen! This helps to explain why the results of skin tests are so inconsistent and puzzling.
The wandering rash
For a baby with atopic eczema, the face, and especially the cheeks, are commonly affected, but there may be a rash all over the legs, the backs of the arms, and the back. As the months go by, the rash settles on the lower legs, and spreads to the fold of the elbow, and then the fold at the back of the knees — by about three years of age, this flexure eczema is the main problem for most children.
In adults, eczema is often found in quite restricted areas, such as the hands, scalp, lips, eyelids or chest. It may be located around the nipples — a sensitive spot where rubbing by clothing is enough to initiate a rash.
Atopic eczema is always in a process of change, and different parts of the body may display different stages of the rash:
• The rash is red and usually dry at first, and there may be not a great deal to see. In this early stage the visible signs may be minimal, while the itchiness can be colossal. Sometimes there is oozing of clear fluid.
• Occasionally the first phase is more marked, with dense patches of small red bumps or tiny blisters. On the hands, these may merge to form larger blisters.
• Infections tend to change the appearance of the rash (see p. 44).
• With time the skin becomes thicker, paler and scaly. It may form leathery patches (called lichenification), especially if there is habitual scratching or rubbing. This is chronic eczema.
• When the eczema clears, there may be an area of skin that is lighter in colour, or darker, than the surrounding skin.
The next step
Whatever causes atopic eczema, it provokes the most horrendous itching, as every eczema sufferer knows. The itch cries out to be scratched, and scratching is the major cause of the visible rash. If left untouched, the skin does not erupt into eczema, although it may well turn red, and there are still distinct changes in the skin that can be seen with a microscope.
Once eczema has erupted, the skin is no longer an intact protective layer that neatly separates ‘in-here’ from ‘out-there’. The skin becomes more permeable and loses its own natural moisture far more readily, so the dryness gets worse. At the same time allergens and irritants penetrate far more easily, causing yet more inflammation.
Something else compounds the damage: once atopic eczema is established, the immune system starts making IgE antibodies to the body’s own proteins, especially those found in skin cells. This helps explain why atopic eczema can become so severe and so entrenched.
Infections — another vicious circle
When eczema erupts and the skin barrier is breached, infections often become a problem. A regular source of trouble is the bacterium Staphylococcus aureus, a cause of the infection impetigo. This microbe invades eczematous skin far more readily than healthy skin, causing a prolific ooze with golden-yellow crusting.
Staphylococcus aureus produces a toxin known as a ’super-antigen’ which revs up the immune system to even more furious effort. This effort does not, unfortunately, oust the bacteria, but it does make the skin inflammation even worse. To add to their woes, many who are afflicted with atopic eczema start making IgE antibodies against Staphylococcus aureus toxins.
Infection with fungi (yeasts and moulds) is also a problem in atopic eczema (see p. 49), and there may be sensitivity reactions to these fungi.
The herpes virus, responsible for causing cold sores, can also invade eczematous skin, though this is much rarer. It worsens the eczema and produces fever and general weakness. There may also be flocks of small red bumps, each with a tiny dimple or blister at the centre. Any symptoms of this kind indicate that the patient needs urgent treatment.
Irritants and stress
People with atopic eczema are far more susceptible to everyday irritants such as wool and rough synthetic fabrics, soap, and traces of detergent left behind in clothes. Chlorinated water, either in swimming pools or from the tap, can also aggravate the skin, and even ‘hard’ water (found in areas with chalk or limestone bedrock) may be a factor.
Some air pollutants may play a part in atopic eczema. Researchers in Germany have found that children living close to busy trunk roads, or in homes with a gas cooker and no extraction hood (see pp. 128-9), were more likely to develop eczema. Formaldehyde fumes, often found in modern houses (see p. 129), are sometimes a factor when eczema affects the face and hands.
