Valsartan — Uses, Dosage, Side Effects & Safety

Drug class: Angiotensin II Receptor Blocker (ARB)

Overview

Valsartan is a prescription medication used to treat high blood pressure (hypertension), heart failure, and to improve survival after a heart attack. Lowering blood pressure helps prevent strokes, heart attacks, and kidney problems. Valsartan works by blocking the action of a natural substance in the body called angiotensin II, which causes blood vessels to tighten. By relaxing blood vessels, valsartan helps blood flow more easily and reduces the workload on the heart. Key points: Take valsartan exactly as prescribed, usually once or twice daily. It may take several weeks to see the full benefit. Do not stop taking valsartan without talking to your doctor, even if you feel well.
