Isradipine

Isradipine is used to treat high blood pressure. It relaxes your blood vessels so your heart does not have to pump as hard. Isradipine is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Isradipine comes as a regular capsule and an extended-release (long-acting) tablet to take by mouth. The capsule is usually taken two times a day, while the tablet is usually taken once a day. The tablet should be swallowed whole. Do not chew, divide, or crush the tablet. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Isradipine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Isradipine controls high blood pressure but does not cure it. Continue to take Isradipine even if you feel well. Do not stop taking Isradipine without talking to your doctor.
