Medication Summary

Medication Summary: This section summarizes DailyMed drug label information to make the label easier to understand. It is not a substitute for the official label, pharmacist counseling, prescriber instructions, or medical advice.

Overview

Hydralazine hydrochloride tablets are an oral antihypertensive medicine used for essential hypertension, either by itself or as an add-on treatment. The tablets come in several strengths, including 10 mg, 25 mg, 50 mg, and 100 mg.

The label says hydralazine works by relaxing blood vessels, which lowers blood pressure and can increase heart rate and cardiac output. It is rapidly absorbed after oral use and is processed by the liver before being excreted mainly in the urine.

The label warns that hydralazine can sometimes cause a lupus-like reaction, including kidney inflammation, and it may also be associated with blood count changes, angina, dizziness, and other side effects. Patients should take it regularly and continuously as directed and may need periodic blood tests during prolonged therapy.
