Clonidine (KLAH-nih-dene)
Brand Names
Catapres-TTS-2
Catapres-TTS-1    Catapres-TTS-3
Type of Drug
Alpha receptor stimulant.
Prescribed For
High blood pressure, including hypertensive emergency (diastolic blood pressure over 120); also used for excess sweating, childhood growth delay, attention-deficit hyperactivity disorder (ADHD), Tourette’s syndrome, restless leg syndrome, schizophrenic psychosis, migraine, ulcerative colitis, painful or difficult menstruation, hot flashes related to menopause, diagnosis of pheochromocytoma (adrenal-gland tumor), kidney poisoning associated with cyclosporine, diabetic diarrhea, smoking cessation, methadone and opiate detoxification, withdrawal from alcohol and benzodiazepines such as Valium, nerve pain following herpes attack, and allergic reactions in the presence of asthma triggered by external sources.
General Information
Clonidine stimulates nerve endings in the brain called alphaadrenergic receptors. It reduces blood pressure by dilating (widening) blood vessels. Clonidine works quickly, decreasing blood pressure within 1 hour. The other uses of clonidine relate to its stimulation of alpha receptors in the body.
Cautions and Warnings
Do not take clonidine if you are allergic or sensitive to any of its ingredients.
People who have had a stroke or recent heart attack or who have cardiac insufficiency or chronic kidney failure should avoid taking clonidine.
Some people develop a tolerance of their clonidine dosage. If this happens, your blood pressure may increase and your doctor may prescribe a higher dose.
Never stop taking clonidine without your doctor’s knowledge. If you abruptly stop taking clonidine, you may experience an unusual increase in blood pressure accompanied by agitation, headache, nervousness, and severe reactions, possibly death. Restarting clonidine therapy or taking another antihypertensive can reverse these effects.
Clonidine may cause degeneration of the    See your eye doctor for regular GheCk Ups lfiyou are taking this drug.
); you require surgery, your doctor will continue your clonidine therapy until about 4 hours before surgery and resume it as soon as possible afterward.
People who develop skin sensitivity (symptoms include rash, itching, and swelling) to Catapres-TTS, the transdermal patch form of clonidine, may experience the same reactions with oral clonidine.
Possible Side Effects
Tablets
♦    Most common: dry mouth, drowsiness, dizziness, constipation, and sedation.
♦    Common: headache and fatigue. These effects tend to diminish within 4-6 weeks.
•    Less common: appetite loss, swelling or pain in the glands of the throat, nausea, vomiting, weight gain, blood-sugar elevation, breast pain or enlargement, worsening of congestive heart failure, heart palpitations, rapid heartbeat, painful blood-vessel spasm, abnormal heart rhythms, electrocardiogram changes, feeling unwell, changes in dream patterns, nightmares, difficulty sleeping, hallucinations, delirium, anxiety, depression, nervousness, restlessness, rash, hives, thinning or loss of scalp hair, difficult or painful urination, nighttime urination, retaining urine, decrease or loss of sex drive, weakness, muscle or joint pain, leg cramps, increased alcohol sensitivity, dryness and burning of the eyes, dry nose, loss of color, and fever.
Transdermal Patch
✓    Most common: dry mouth and drowsiness.

Rashes of the face and tongue have also occurred but cannot be specifically tied to transdermal clonidine.
Drug Interactions
•    Combining clonidine and a beta-adrenergic blocker may increase the severity of a drug-withdrawal reaction and rebound high MW pressure. This reaction may be very serious.
•    Combining verapamil and clonidine may lead to very low blood pressure and atrioventricular (AV) block (abnormality in heartbeat patterns). This reaction may be very serious.
O    Avoid alcohol, barbiturates, and sedatives because they increase the depressive effects of clonidine.
•    Tricyclic and other antidepressants, appetite suppressants, estrogens, stimulants, indomethacin and other nonsteroidal anti-inflammatory drugs (NSAIDs), and prazosin may counteract the effects of clonidine.
•    clonidine may reduce the therapeutic effects of levadopa +
carbidopa.
Food Interactions
The tablets are best taken on an empty stomach but may be taken with food if they upset your stomach.
Usual Dose
Tablets
Adult: high blood pressure-100 mcg twice a day to start; may be raised by 100 mcg a day until maximum control is achieved. Take no more than 2400 mcg a day. Other uses-100-goo mcg a day, or up to 0.8 mcg per lb. of body weight in divided doses. Seniors should start with a lower dose and increase more slowly.
Child: 50-400 mcg orally twice a day.
Transdermal Patch
Adult: 100 mcg delivered daily from a patch applied once every 7 days. Up to two 300-mcg patches may be needed to control blood pressure. Transdermal dosage exceeding 600 mcg a day has not been shown to increase effectiveness.
Child: not recommended.
Overdosage
Symptoms of overdose are slow heartbeat, central- nervous-system depression, very slow breathing, low body temperature, pinpoint pupils, seizures, lethargy, agitation, irritability, nausea, vomiting, abnormal heart rhythms, mild increases in blood pressure followed by a rapid drop in blood pressure, dizziness, weakness, loss of reflexes, and vomiting. Victims should be taken to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special Information
Gk’3t1161)e causes drowsiness in about 1/3 of people who take it. Be extremely careful while driving or performing any task that requires concentration. This effect is prominent during the first few weeks of clonidine therapy and then tends to decrease.
Do not take over-the-counter cough and cold medications unless directed by your doctor.
Call your doctor it you become depressed or have vivid dreams or nightmares while taking clonidine, or if you develop swelling in your feet or legs, paleness or coldness in your fingertips or toes, or any persistent or bothersome side effect.
Apply the transdermal patch to a hairless area of skin such as the upper arm or torso. Use a different skin site each time. If the patch becomes loose, apply the supplied adhesive directly over it. If the patch falls off before 7 days are up, apply a new one. Do not remove the patch while bathing.
If you forget a dose of oral clonidine, take it as soon as possible and then go back to your regular schedule. If you miss 2 or more consecutive doses, consult your doctor; missed doses may cause blood pressure increases and severe adverse effects. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Clonidine passes into the fetal bloodstream. Animal studies show that clonidine may damage the fetus in doses as low as 1/3 the maximum dose. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
Clonidine passes into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors are more susceptible to the effects of this drug and should begin with lower doses.

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

Generic Name
Clorazepate (klor-AZ-uh-pate) 99
Brand Names
Gen-Xene    Tranxene-SD
Tranxene    Tranxene T-Tab
Type of Drug
Benzodiazepine sedative.
Prescribed For
Anxiety, tension, fatigue, and agitation; symptoms of acute alcohol withdrawal; partial seizures; also prescribed for irritable bowel syndrome and panic attacks.
General Information
Clorazepate dipotassium is a benzodiazepine. Benzodiazepines directly affect the brain. They can relax you and make you more tranquil or sleepier, or they can slow nervous system transmissions in such a way as to act as an anticonvulsant. Many doctors prefer benzodiazepines to other drugs that can be used to similar effect because they tend to be safer, have fewer side effects, and usually work as well, if not better.
Cautions and Warnings
Do not take clorazepate if you are allergic or sensitive to any of its ingredients or to another benzodiazepine drug, including clonazepam.
Clorazepate can aggravate narrow-angle glaucoma, but you may take it if you have open-angle glaucoma and are receiving therapy for it.
Other conditions in which clorazepate should be avoided are: severe depression, severe lung disease, sleep apnea (intermittent cessation of breathing during sleep), liver disease, drunkenness, and kidney diseaap_, to inOn of these conditions, the qq)NSSvve effects of clorazepate may be enhanced or could be detrimental to your overall condition.
Clorazepate should not be taken by psychotic patients because it is not effective for them and can trigger unusual excitement, stimulation, and rage.
Clorazepate is not intended to be used for more than 3-4 months at a time. Your doctor should reassess your condition before continuing your prescription beyond that time.
Clorazepate may be addictive. It should be used with caution in people with a history of drug dependence.
Drug withdrawal may develop if you stop taking it after as few as 4 weeks of regular use but is more likely after longer use. It may start with anxiety and progress to tingling in the hands or feet, sensitivity to bright light, sleep disturbances, cramps, tremors, muscle tension or twitching, poor concentration, flu-like symptoms, fatigue, appetite loss, sweating, and changes in mental state. Your dosage should always be reduced gradually to prevent drug withdrawal symptoms.
Possible Side Effects
Weakness and confusion may occur, especially in seniors and in those who are more sickly.
✓    Most common: mild drowsiness during the first few days of therapy.
✓    Less common: confusion, depression, lethargy, disorientation, headache, inactivity, slurred speech, stupor, dizziness, tremors, constipation, dry mouth, nausea, inability to control urination, sexual difficulties, irregular menstrual cycle, changes in heart rhythm, low blood pressure, fluid retention, blurred or double vision, itching, rash, hiccups, nervousness, inability to fall asleep, and occasional liver and kidney dysfunction. If you have any of these symptoms, stop taking the medicine and contact your doctor immediately.
✓    Rare: Rare side effects can affect your heart, stomach and intestines, urinary tract, blood, muscles and joints. Contact your doctor if you experience any side effects not listed above.
Drug Interactions
•    Clorazepate is a central-nervous-system depressant. Don’t mix it with alcohol, other sedatives, narcotics, barbiturates, monoamine oxidase inhibitor and other antidepressants, and antihistamines. Taking Clorazepate with these drugs may result in excessive depression, tiredness, sleepiness, breathing difficulties, or related symptoms.
•    Smoking may reduce clorazepate’s effectiveness by in-
creasing the rate at which it is broken down by the body.
•    Clorazepate’s effects may be prolonged when it is mixed with cimetidine, contraceptive drugs, disulfiram, fluoxetine, isoniazid, ketoconazole, metoprolol, probenecid, propoxyphene, propranolol, rifampin, or valproic acid. Theophylline may reduce clorazepate’s sedative effects.
•    If you take antacids, separate them from your clorazepate dose by at least 1 hour to prevent them from interfering with the absorption of clorazepate into the bloodstream.
•    Clorazepate may increase blood levels of digoxin and the chances of digoxin toxicity.
•    The effect of levodopa + carbidopa may be decreased if it is taken together with clorazepate.
•    Combining clorazepate with phenytoin may increase phenytoin blood concentrations and the chances of phenytoin toxicity.
Food Interactions
Clorazepate is best taken on an empty stomach, but it may be taken with food if it upsets your stomach.
Usual Dose
Immediate-Release
Adult and Child (age 9 and over): 15-60 mg daily. The average dose is 30 mg in divided quantities, but dosage must be adjusted to individual response for maximum effect. Maximum recommended daily dose is 90 mg. For treatment of anxiety, clorazepate may be taken as a single dose at bedtime.
Child (under age 9): not recommended.

Clorazepate may pass into breast milk. Nursing mothers who must take clorazepate should use infant formula.
Seniors: Seniors, especially those with liver or kidney disease, are more sensitive to the effects of clorazepate and generally require smaller doses to achieve the same effect.

Generic Name
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.

Generic Name
Brimonidine (brim-ON-ih-dene) (9
Brand Name  Alphagan P
Type of Drug Alpha agonist.
Prescribed For
Glaucoma and ocular hypertension (high pressure inside the eye).
General Information
Brimonidine tartrate stimulates alpha-2 receptors in the eye and lowers pressure there. The maximum effect occurs 2 hours after the drops are administered. Brimonidine reduces the amount of aqueous humor (liquid) produced inside the eye and increases the rate at which fluid flows out of the eyeball. That portion of brimonidine that finds its way into the bloodstream is broken down by the liver.
Cautions and Warnings
Do not use brimonidine if you are allergic or sensitive to any of its ingredients.
People with kidney or liver disease should use this drug with caution. People with cardiovascular disease should exercise caution with this medication because it can affect blood pressure. It should be used with caution in people with depression, cerebral or coronary insufficiency, and Raynaud’s disease. Brimonidine may cause fatigue, drowsiness, and dizziness or fainting when rising from a sitting or lying position.
Brimonidine’s effectiveness may decrease over time. Your doctor should check your eye pressure periodically to make sure the drug is still working.
Possible Side Effects
