Uses

CAPTOPRIL (Capoten) is an antihypertensive (blood pressure lowering agent) known as an ACE inhibitor. Captopril controls high blood pressure (hypertension) by relaxing blood vessels; it is not a cure. High blood pressure levels can damage your kidneys, and may lead to a stroke or heart failure. Captopril also can help to treat heart failure (heart does not pump strongly enough) and certain kidney disorders. Generic captopril tablets are available.

How to take

Take captopril tablets by mouth. Follow the directions on the prescription label. Swallow the tablets with a drink of water. Take captopril on an empty stomach, at least 1 hour before or 2 hours after meals. Take your doses at regular intervals. Do not take your medicine more often than directed. Do not stop taking captopril except on your prescriber's advice. Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.

Precaution

Visit your prescriber or health care professional for regular checks on your progress. Check your blood pressure regularly while you are taking captopril. Ask your prescriber or health care professional what your blood pressure should be and when you should contact him or her. Call your prescriber or health care professional if you notice an uneven or fast heart beat. Do not treat yourself for a fever or sore throat; check with your prescriber or health care professional as these may be the result of a captopril side effect. Check with your prescriber or health care professional if you get an attack of severe diarrhea, nausea and vomiting, or if you sweat a lot. The loss of body fluid can make it dangerous to take captopril. You may get dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how captopril affects you. To avoid dizzy or fainting spells, do not stand or sit up quickly, especially if you are an older person. Alcohol can make you more dizzy. Avoid alcoholic drinks. If you are going to have surgery, tell your prescriber or health care professional that you are taking captopril. Avoid salt substitutes or other foods or substances high in potassium salts. Do not treat yourself for coughs, colds, or pain while you are taking captopril without asking your prescriber or health care professional for advice. Antacid can stop captopril working. If you want to take antacid for an upset stomach, make sure there is an interval of at least 2 hours since you last took captopril, or 4 hours before your next dose. Captopril can alter certain lab test results, giving a false-positive for urine ketone tests.
