Generic Name
Carbamazepine (car-bam-A-zuh-pene)
Brand Names
Atretol    Tegretol
Carbatrol    Tegretol-XR
Epitol    Teril Equetro
Type of Drug
Anticonvulsant.
Prescribed For
Seizure disorders as well as other neuralgias; also  severe pain; psychiatric disorders including depression, bipolar disorder, intermittent explosive disorder, borderline personality disorder, post-traumatic stress disorder, psychotic disorders, and schizophrenia; withdrawal from alcohol, cocaine, or benzodiazepine-type drugs; restless leg syndrome; hereditary and non-hereditary chorea in children; and diabetes insipidus.
General Information
Carbamazepine was first approved for relief of the severe pain of trigeminal neuralgia. Over the years, it has gained wide use in seizure control, especially in people whose seizures are uncontrolled with phenytoin, phenobarbital, or primidone, or who have suffered severe side effects from these drugs. Carbamazepine is not a simple pain reliever and should not be taken for everyday aches and pains. It is associated with potentially fatal side effects.
Cautions and Warnings
Carbamazepine should not be used if you are allergic or sensitive to any of its ingredients or to any tricyclic antidepressant.
Carbamazepine should not be used if you have had bone marrow depression.
Carbamazepine may cause severe, possibly life-threatening blood reactions. People who have had blood reactions to other drugs are at particular risk for another reaction with carbarnazepine. Your doctor should have a complete blood count done before you start taking this drug and repeat these tests weekly during the first 3 months of treatment, and then every month for the next 2-3 years. Unexplained fever or infection may be a sign of a blood reaction.
Monoamine oxidase inhibitor (MA01) antidepressants should be discontinued 2 weeks before starting carbamazepine.
Rarely, severe, possibly fatal skin reactions can develop in a few people taking carbamazepine. Asians are 10 times more likely to develop these reactions than non-Asians.
Carbamazepine may aggravate glaucoma and should be used with caution by people with this condition. This drug may activate underlying psychosis, and, in older adults, confusion or agitation.
This drug is not for the relief of minor aches or pains.
Possible Side Effects
V Most common: dizziness, drowsiness, unsteadiness, nausea, and vomiting. Other common side effects are blurred W double vision, confusion, hostility, headache, and severe water retention.
♦ Less common: mood and behavioral changes, especially in children. Hives, itching, rash, and other allergic reactions may also occur.

Drug Interactions
•    Carbamazepine blood levels may be increased by azoles (e.g. ketoconazole), acetazolamide, cimetidine, dalfopristin, danazol, delavirdine, diltiazem, haloperidol, isoniazid, propoxyphene, erythromycin-type antibiotics (except azithromycin), fluoxetine, fluvoxamine, loratadine, levetiracetam, macrolides, MAOls, nefazodone, niacinamide, nicotinamide, protease inhibitors, quinine, quinupristin, terfenadine, tricyclic antidepressants, valproate, verapamil, or zileuton, leading to possible carbamazepine toxicity.
•    Carbamazepine may reduce the effectiveness of contraceptive drugs and cause breakthrough bleeding.
•    Charcoal tablets or powder, clozapine, methsuximide phenobarbital and other barbiturates, phenytoin, primidone and theophylline may decrease the absorption of carbamazepine. Levels of phenobarbital, a breakdown product of primidone, may be increased by combining primidone and carbamazepine.
•    Carbamazepine reduces the effects of acetaminophen, the anticoagulant (blood thinner) warfarin, and theophylline (prescribed for asthma). Increased dosage of these drugs may be necessary. Other drugs counteracted by carbamazepine are antipsychotics (e.g. aripiprazole, clozapine, olanzapine, quetiapine, risperidone, and ziprasidone), benzodiazepines (e.g. diazepam and lorazepam), bupropion, cyclosporine, digitalis drugs, doxycycline, felodipine, lamotrigine, levothyroxine, methadone, mirtazapine, certain muscle relaxants, oxcarbazepine,  slatin drugs, tiagibine, topiramate, tramadol, and zonisamide.
•    Combining carbamazepine and other antiseizure drugs, including felbamate, hydantoins, succinimides, and valproic acid, may cause unpredictable results. Combination treatments to control seizures must be customized to each person.
Possible Side Effects (continued)
♦ Rare: Rare side effects can affect
liver function, urinary    other
parts of the body. Contact you    you any side effect not listed above.
•    Combining carbamazepine and lithium may increase nervous system side effectssuch as muscular twitching or im-
paired consciousness.
•    Carbamazepine suspension should not be combined with
other liquid medicines or diluents.
Food Interactions
Take carbamazepine with food if it causes stomach upset. Avoid taking carbamazepine with grapefruit products.
Usual Dose
Adult and Child (age 13 and over): 400-1200 mg a day, depending on the condition. Usual maintenance dose is 400-800 mg a day in 2 divided doses.
Child (age 6-12): 200-1000 mg a day, or 22-24 mg per lb. of body weight 2-3 times a day for suspension or 4 times a day for tablets. Do not exceed 1000 mg a day.
Child (under age 6): 22-24 mg per lb. of body weight 2-3 times a day for suspension or 4 times a day for tablets; dosage should not exceed 77 mg per 1b. of body weight a day.
Dosage varies according to form. Liquid carbamazepine must be taken 3 times a day, regular carbamazepine tablets twice a day, and sustained-release tablets once daily. Never change your dosage schedule without first checking with your doctor.
Overdosage
Carbamazepine is a potentially lethal drug. Overdose symptoms appear in 1-3 hours. These include irregularity or difficulty in breathing, rapid heartbeat, changes in blood pressure, shock, loss of consciousness or coma, convulsions, muscle twitching, restlessness, uncontrolled body movements, drooping eyelids, psychotic mood changes, nausea, vomiting, and reduced urination. Induce vomiting right away with ipecac syrup—available at any pharmacy. Then take the victim to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Mormation
Carbamazepine may cause dizziness and drowsiness. Take care while driving or doing any task that requires concentration.
Call your doctor at once if you experience yellowing of the skin or whites of the eyes, unusual bleeding or bruising, abdominal pain, pale stools, dark urine, impotence, mood changes, nervous system symptoms, swelling, fever, chills, sore throat, or mouth sores. These may be signs of a potentially fatal drug reaction.
If you forget a dose, skip it and go back to your regular schedule. it you miss more than I dose in a day, call your doctor. Do not stop taking this drug without first consulting your doctor.
Special Populations
Pregnancy/Breast-feeding: Carbamazepine caused birth defects in animal studies. Seizure disorder itself also increases the risk of birth defects. Pregnant women should take carbamazepine only after discussing with their doctors its potential benefits and risks.
Carbamazepine passes into breast milk. Nursing mothers who must take carbamazepine should use infant formula.
Seniors: Seniors taking this drug are more likely to develop heart Problems, confusion, or agitation.

Generic Name
Captopril (KAP-toe-pril)
Brand Name  Capoten
Combination Products
Generic Ingredients: Captopril + Hydrochlorothiazide [M Capozide
Type of Drug
Angiotensin-converting enzyme (ACE) inhibitor.
Prescribed For
High blood pressure and heart failure; diabetic kidney damage and post-heart attack management; also used for kidney hyperten-Sion, the management of people with a high risk of heart disease, chronic kidney disease, the prevention of a second stroke, and high blood pressure associated with other medical conditions, such as scleroderma and Takayasu’s disease.
General Information
Captopril and other ACE inhibitors work by preventing the conversion of a hormone called angiotensin I to another hormone called angiotensin 11, a potent blood-vessel constrictor. Preventing this conversion relaxes blood vessels, helps to reduce blood pressure, and relieves the symptoms of heart failure. Captopril also affects the production of other hormones and enzymes that participate in the regulation of blood-vessel dilation. Captopril usually begins working about 1 hour after it is taken.
In addition to its labeled uses, captopril has been studied in the diagnosis of certain kidney diseases and of primary aldosteronism; in the treatment of rheumatoid arthritis; in swelling and fluid accumulation; in Bartter’s syndrome; in Raynaud’s disease; and in post–heart attack treatment when the function of the left ventricle is affected.
Cautions and Warnings
Do not take captopril if you are allergic or sensitive to any of its ingredients. Severe sensitivity reactions can occur in hemodialysis patients or in those undergoing venom immunization.
People with impaired kidney function should not take captopril unless other anti hypertensives have not worked or have had unacceptable side effects.
Swelling of the face, extremities, or throat has been known to occur with captopril, which can be dangerous (see “Special Information”).
Although not common, captopril may cause very low blood pressure. It may also affect your kidneys, especially if you have congestive heart failure. Your doctor should check your urine for protein content during the first few months of captopril treatment. Captopril may cause a decline in kidney function.
Captopril may affect white-blood-cell counts, possibly increaSlN I)Ur susceptibility to infection. Your doctor should monitor your blood counts periodically.
Captopril can cause serious injury or death to the fetus if taken during pregnancy. Pregnant women should not take captopril.
ACE inhibitors may be less effective in some black patients with high blood pressure, especially when dietary salt intake is high. Nevertheless, they should still be considered useful blood pressure treatments. Swelling beneath the skin to form welts is more common among black patients.
Possible Side Effects
♦    Most common: rash, itching, and cough that usually goes away a few days after you stop taking the drug.
✓    Less common: dizziness, tiredness, sleep disturbances, headache, tingling in hands or feet, chest pain, heart palpitations, feeling unwell, abdominal pain, nausea, vomiting, diarrhea, constipation, appetite loss, dry mouth, breathing difficulties, and hair loss.
♦    Rare: 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
•    The blood-pressure-lowering effect of captopril is additive with diuretic drugs and beta blockers. Any other drug that causes a rapid blood-pressure drop should be used with caution if you are taking captopril.
•    Combining 325 mg of aspirin a day with captopril carries a higher risk of death than taking lower doses (less than 160 mg a day). People taking aspirin to prevent a heart attack should use the lower dose.
•    Captopril may increase the effects of lithium; this combination should be used with caution.
•    Mixing any ACE inhibitor with an NSAID pain reliever can increase the chances of kidney failure.
•    Severe sensitivity reactions can occur in those taking allopurinol.
•    Captopril may increase blood-potassium levels, especially when taken with dyazide or other potassium-sparing diuretics.
•    Antacids and captbe taken at least 2 hours apart. 1 tapsaicin may trigger or aggravate the cough associated with captopril.
•    Inclomethacin may reduce the blood-pressure-lowering effect of captopril.
•    Phenothiazine sedatives and antivomiting agents may increase the effects of captopril.
•Probenecid increases captopril’s effect as well as the chance of side effects.
•    The combination of allopurinol and captopril increases the chance of an adverse drug reaction.
•    Captopril may affect blood levels of digoxin. More digoxin in
the blood increases the chance of digoxin-related side ef-
fects, while less digoxin in the blood can compromise its
effectiveness.
Food Interactions
Captopril should be taken 1 hour before a meal.
Usual Dose
Adult: 25 mg 2 or 3 times a day to start. Dosage may be increased to 450 mg a day in divided doses, if needed. Dosage must be tailored to your needs. People with poor kidney function must take lower doses.
Child: 0.14-0.28 mg per lb. of body weight, 3 times a day. Infant: 0.07-0.14 mg per 1b. of body weight.
Overdosage
The principal effect of captopril overdose is a rapid drop in blood pressure, which may lead to dizziness or fainting. Take the overdose victim to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special Information
Captopril may cause swelling of the face, lips, hands, and feet. This swelling may also affect the larynx (throat) and tongue and interfere with breathing. If this happens, go to a hospital emergency room at once. Call your doctor if you develop a sore throat, mouth sores, abnormal heartbeat, chest pain, a persistent rash, or losses in the sense of taste.
People who are already taking a diuretic (an agent that increases urination) may experience a rapid blood-pressure drop after their first dose of captopril or when their captopril dose k!Z,iTlr_Teased. To prevent this, your doctor may tell ‘you to stop taking your diuretic or to OYtM8 _’ your salt intake 2 or 3 days before starting captopril. The diuretic may then be restarted gradually.
You may get dizzy if you rise to your feet too quickly from a sitting or lying position when taking captopril.
Avoid strenuous exercise or very hot weather because heavy sweating or dehydration may lead to a rapid drop in blood pressure.
Avoid over-the-counter stimulants that can raise blood pressure while taking captopril, including diet pills and decongestants. Also, do not use potassium supplements or salt substitutes containing potassium without consulting your doctor.
If you forget to take a dose of captopril, take it as soon as you remember. If it is within 4 hours of your next dose, take 1 dose immediately and another in 5 or 6 hours, then go back to your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: ACE inhibitors can cause fetal injury or death. Women who are or might be pregnant should not take ACE inhibitors. If you become pregnant, stop taking captopril and call your doctor immediately.
Small amounts of captopril pass into breast milk. Nursing mothers who must take this drug should consider using infant formula.
Seniors: Seniors may be more sensitive to the effects of captopril due to age-related declines in kidney or liver function.

It is not known if capecitabine passes into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors may be more sensitive to side effects, especially diarrhea and other stomach problems.

Generic Name
Calcitonin (kal-sih-TOE-nin)
General Information
Calcitonin helps to strengthen bone by adding more calcium to it and slowing the natural process by which bone is broken down. The calcitonin used in this drug is essentially identical to human calcitonin except that it is more potent. It is a synthetic version of the natural calcitonin found in salmon. Calcitonin can increase bone density and reduce the risk of fractures of the vertebrae (bones that comprise the spinal column), which are associated with back pain and loss of height. Calcitonin has been available for years as an injection, but the development of the nasal spray makes the drug easier to use.
Cautions and Warnings
Do not use calcitonin if you are allergic or sensitive to any of its ingredients. Although serious allergic reactions were reported with the injectable form, none have occurred with the nasal spray.
Changes in the tissues lining your nose are possible with longerm use of this product. An initial nasal examination and then peiodic examinations are recommended.
Possible Side Effects
V Most common: stuffy nose, runny nose, and other nasal symptoms; and back pain.
V Less common: joint pain, nosebleed, and headache.
Drug Interactions
None known.
Food Interactions
None known. Usual Dose
Adult: I spray (200 IU) a day. Child: not recommended.
Little is known about the effects of calcitonin overdose or accidental ingestion. Nausea and vomiting have been reported after high doses. Call your local poison control center for more information. Overdose victims should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Alternate nostrils daily when using the nasal spray.
Before you take your first dose, you must activate the pump. Hold the bottle upright and press the two white arms toward the bottle 6 times until a faint spray is emitted. Once this occurs, the pump is activated and ready for use. It is not necessary to reactivate the pump every day.
Store new, unassembled bottles in the refrigerator. Keep the bottle in use at room temperature and discard after 30 days.
If you forget to administer a dose of the nasal spray, do so as soon as you remember. If it is almost time for the next dose, skip the dose you forgot and continue with your regular schedule. Call your doctor if you forget 2 or more doses.
Call your doctor if you develop severe nose irritation or any unusual or intolerable symptom. Follow your doctor’s recommendations regarding calcium and vitamin D supplements. This drug is not intended to replace the need for dietary calcium.
Special Populations
Pregnancy/Breast-feeding: calcitonin does not cross into the fetal circulation, though animal studies have associated the injectable form of the drug with low birth weight. This drug is recommended for use during pregnancy only if its possible benefits outweigh its risks.
It is not known if calcitonin passes into breast milk, though animal studies have shown that it reduces the amount of milk produced. Nursing mothers who must use calcitonin should consider using infant formula.
Seniors: Seniors may use this product without special precaution.

Generic Name
Buspirone (bue-SPYE-rove) OG
Brand Name  BuSpar
Type of Drug
Minor sedative and antianxiety drug.
Prescribed For
Anxiety and generalized anxiety disorders; also prescribed for the aches, pains, fatigue, and cramps of premenstrual syndrome (pMS).
General Information
Buspirone hydrochloride has a potent antianxiety effect. It is approved by the Food and Drug Administration (FDA) for short-term relief of anxiety, but it may apparently be used safely for more than 4 weeks. The exact way in which buspirone works is not known, but it seems to lack the addiction dangers associated with other antianxiety drugs, including benzodiazepines. It neither severely depresses the nervous system nor acts as an anticonvulsant or muscle relaxant, as other antianxiety drugs do. Minor improvement will be apparent after only 7-10 days of drug treatment, but the maximum effect does not occur for 3 or 4 weeks.
Cautions and Warnings
Do not take buspirone if you are allergic or sensitive to any of its ingredients.
Buspirone should be used cautiously by people with timer or kidney disease.
Buspirone does not have any antipsychotic effect and should not be taken for symptoms of psychosis.
Although buspirone has not shown a potential for drug abuse, you should be aware of this possibility.
Buspirone should not be used with monamine oxidase inhibitor (MAGI) antidepressants.
Possible Side Effects
♦    Most common: dizziness, drowsiness, nausea, and head-
ache.
•    Common: fatigue, nervousness, lightheadedness, excite-
ment, dry mouth, and insomnia.
•    Less common: heart palpitations, muscle aches and pains, tremors, rash, sweating, clamminess, rapid heartbeat, dif-
ficulty concentrating, anger or hostility, depression, loss of interest, diarrhea, constipation, vomiting, and blurred vision.
♦    Rare: 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
•    Combining buspirone with an MAGI antidepressant may produce severe hypertension and may be dangerous.
•    The effects of combining buspirone with other drugs that work in the central nervous system (CNS) are not known. Do not take other sedatives or antianxiety or psychoactive drugs with buspirone unless prescribed by a doctor familiar with your complete medical history.
•    Erythromycin, itraconazole, ketoconazole, clarithromycin, diltiazem, verapamil, fluvoxamine, and ritonavir may increase blood levels of buspirone. When used in combination, your buspirone dosage may need to be adjusted.
•    Buspirone may increase the side effects of haloperidol and diazepam.
•    Studies show that buspirone is not affected by alcohol, but this combination should still be used with caution because buspirone causes drowsiness and dizziness.
•    The combination of buspirone and trazodone may cause liver inflammation.
•    Combining rifampin with buspirone may decrease buspirone’s effectj\18″eSS.
Food Interactions
This drug may be taken either with or without food, but for the most consistent results, always take your dose at the same time of day in the same way—that is, with or without food. Avoid drinking large amounts of grapefruit juice with this drug.
Usual Dose
Adult: starting dosage-7.5 mg twice a day. Dosage may be increased gradually to 60 mg a day.
Overdosage
Symptoms of overdose are nausea, vomiting, dizziness, drowsiness, pinpointed pupils, and upset stomach. The overdose victim should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Buspirone may cause CNS depression, drowsiness, and dizziness. Be careful while driving or operating hazardous equipment. Avoid other CNS drugs and alcoholic beverages because they will enhance buspirone’s effects.
Contact your doctor if you become restless, develop uncontrolled or repeated movements of the head, face, or neck, or have any intolerable side effects.
If you forget a dose, take it as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and go back to your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Though buspirone has not been found to cause birth defects, be sure to inform your doctor if you are or might be pregnant while taking this drug. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
It is not known how much buspirone passes into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Several hundred seniors participated in drug evaluation studies without any unusual problems. However, the effect of this drug in seniors is not well known, and special problems may surface, particularly in those with kidney or liver disease.

Generic Name
Bupropion (bue-PROE-pee-on) M
Brand Names
Budeprion    Wellbutrin SR
Budeprion XL    Wellbutrin XL
Wellbutrin    Zyban
Type of Drug
Antidepressant and smoking deterrent.
Prescribed For
Depression, seasonal affective disorder, and nicotine addiction.
General Information
Bupropion is used for major depression and seasonal affective disorder, and may work as a smoking deterrent by acting on key hormone systems in the brain. It works primarily on dopamine and noradrenaline, unlike the SSRI antidepressants, which primarily work on serotonin. Bupropion may not act until you have taken it for 2-4 weeks. The drug clears your system about 2 weeks after you stop taking it.
Cautions and Warnings
Do not take bupropion if you are allergic or sensitive to any of its ingredients.
Antidepressants have been associated with an increased risk of suicide, especially in children and teenagers. Suicide is always a risk in depressed people, who should only be allowed to have minimal quantities of medication in their possession. Clinical worsening of a depressed person’s condition may also occur early
therapy with anticlepressa”kS.
People with seizure disorders, people who have had a seizure in the past, and people with bulimia or anorexia nervosa should be very careful about taking bupropion because they are at a higher risk of having a seizure. About 4 in 1000 people taking bupropion in dosages up to 450 mg a day develop a seizure. The risk of developing a seizure increases by about 10 times with dosages between 450 and 600 mg a day. About half of the people who developed a seizure on bupropion had a risk factor such as a history of head injury, a previous seizure, or a nervous system tumor, or were taking another drug associated with increased seizure risk.
People with unstable heart disease or those who have had a recent heart attack should take this drug with caution because of possible side effects.
Many people taking bupropion experience some restlessness, agitation, anxiety, and sleeplessness, especially soon after they start taking the drug. Some even require sleeping pills to counter this effect, and others find the stimulation so severe that they have to stop taking bupropion.
Bupropion may trigger a manic episode in those with depression or bipolar disorder.
People taking bupropion may experience hallucinations, delusions, or psychotic episodes. Dosage reduction or drug withdrawal is usually necessary to manage these reactions.
One-quarter of those who take bupropion lose their appetite and 5 or more lbs. of body weight. People who have lost weight due to their depression should be cautious about taking bupropion.
People switching from bupropion to a monoamine oxidase inhibitor (MA01) antidepressant, or vice versa, should allow at least 2 weeks to pass between stopping one drug and starting the other.
People with kidney or liver disease require less bupropion at the beginning of treatment. Dosage should be increased cautiously.
An antidepressant other than bupropion should be seriously considered for people with a history of drug abuse because of the mild stimulation bupropion causes. These people may require larger-than-usual dosages, but they are still susceptible to seizures at these higher dosages.
Possible Side Effects
About 10% of people stop taking bupropion due to side effects.
♦ Most common: dry mouth; dizziness; rapid heartbeat; headache, including migraine; excessive sweating; nausea; vomiting; constipation; appetite loss; weight changes: sedation; agitation; sleeplessness; and tremors.
Possible Side Effects (continued)

Type of Drug     Endothelia receptor antagonist.
Prescribed For
Pulmonary arterial hypertension.
General Information
These drugs lower blood pressure by working on the endothelin system. Endothelia is a hormone that plays an important role in maintaining blood pressure. It is normally found in blood vessels, but endothelin levels are very high in the blood and lungs of people with pulmonary arterial hypertension. People with this condition have high blood pressure, trouble breathing, and get very tired even when walking or doing other moderate exercising. Pulmonary arterial hypertension can be fatal.
Cautions and Warnings
These drugs should not be used by those who are allergic or sensitive to any of their ingredients.
Bosentan can cause liver injury. People taking these drugs should have their liver enzymes checked monthly. Enzyme increases can be a sign of liver injury and may be a reason to stop taking bosentan.
These drugs are broken down in the liver. People with liver damage should take them with caution.
These drugs should not be taken during pregnancy as they are likely to cause birth defects (see “Special Populations”).
