For intravenous and intramuscular administration

Severe essential hypertension when the drug cannot be given orally or when there is an urgent need to lower blood pressure.


Hypersensitivity to hydralazine; coronary artery disease; mitral valvular rheumatic heart disease.

Hydralazine may produce a clinical picture simulating systemic lupus erythematosus, necessitating discontinuation unless the benefit-to-risk determination requires continued antihypertensive therapy with this drug. Symptoms and signs usually regress when the drug is discontinued but residua have been detected many years later.

General: Myocardial stimulation produced by hydralazine can cause anginal attacks and ECG changes of myocardial ischemia including myocardial infarction.
Use with caution in patients with suspected coronary artery disease or advanced renal damage.

Laboratory Tests: Complete blood counts and antinuclear antibody titer determinations are indicated before and periodically during prolonged therapy.
Blood dyscrasias have been reported. If such abnormalities develop, therapy should be discontinued.

Drug Interactions: MAO inhibitors; other antihypertensive drugs.

Pregnancy: Teratogenic effects. Pregnancy Category C:

There are no adequate and well-controlled studies in pregnant women. Hydralazine should be used during pregnancy only if the expected benefit justifies the potential risk to the fetus.

Nursing Mothers: Hydralazine has been shown to be excreted in breast milk.

Pediatric Use: Safety and effectiveness in pediatric patients have not been established.
