What is hydralazine (Apresoline)?
Hydralazine is a vasodilator that works by relaxing the muscles in your blood vessels to help them dilate (widen). This lowers blood pressure and allows blood to flow more easily through your veins and arteries.
Hydralazine is used to treat high blood pressure (hypertension).
Hydralazine may also be used for other purposes not listed in this medication guide.

To be sure this medication is helping your condition and is not causing harmful effects, your blood pressure will need to be checked often. You may also need occasional blood tests. Do not miss any scheduled appointments.
Keep using hydralazine as directed, even if you feel well. High blood pressure often has no symptoms, so you may not know when your blood pressure is high. You may need to use blood pressure medication for the rest of your life.
