Captopril Side Effects
What should I watch for?
Visit your doctor or health care professional for regular checks on your progress. Check your blood pressure as directed. Ask your doctor or health care professional what your blood pressure should be and when you should contact him or her. Call your doctor or health care professional if you notice an irregular or fast heart beat.
Women should inform their doctor if they wish to become pregnant or think they might be pregnant. There is a potential for serious side effects to an unborn child. Talk to your health care professional or pharmacist for more information.
Check with your doctor or health care professional if you get an attack of severe diarrhea, nausea and vomiting, or if you sweat a lot. The loss of too much body fluid can make it dangerous for you to take this medicine.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can make you more drowsy and dizzy. Avoid alcoholic drinks.
Avoid salt substitutes unless you are told otherwise by your doctor or health care professional.
Do not treat yourself for coughs, colds, or pain while you are taking this medicine without asking your doctor or health care professional for advice. Some ingredients may increase your blood pressure.
