Hydralazine is a prescription medicine used to treat the symptoms of severe essential hypertension, chronic high blood pressure, hypertensive crisis, and congestive heart failure. It may be used alone or with other medications.

While on Hydralazine, follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Please do not take more or less of it or more often than prescribed by your doctor. It usually comes as a tablet to take by mouth. Usually, Hydralazine is taken two to four a day. Take Hydralazine at around the same times every day.

Hydralazine controls high blood pressure but does not cure it. Continue to take Hydralazine even if you feel well. Do not stop taking Hydralazine without talking to your doctor.
