Hydralazine: Uses, Dosage, Side Effects, and More

Hydralazine is a prescription vasodilator used to treat high blood pressure (hypertension) by relaxing blood vessels, allowing blood to flow more easily and reducing strain on the heart. It is sometimes prescribed in combination with other medications for severe hypertension or heart failure management.
