  • Antihypertensive
  • Vasodilator, congestive heart failure

Hydralazine (hye-DRAL-a-zeen) belongs to the general class of medicines called antihypertensives. It is used to treat high blood pressure (hypertension). It is also used to control high blood pressure in the mother during pregnancy (pre-eclampsia or eclampsia) or in emergency situations when blood pressure is extremely high (hypertensive crisis).

High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

Hydralazine works by relaxing blood vessels and increasing the supply of blood and oxygen to the heart while reducing its workload.

Hydralazine may also be used for other conditions as determined by your doctor.

Hydralazine is available only with your doctor's prescription, in the following dosage forms:

  • Oral solution (must be prepared by the pharmacist)
  • Tablets (U.S. and Canada)
  • Injection (U.S. and Canada)
