Diovan (valsartan) is an angiotensin II receptor blocker (sometimes called an ARB). Valsartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
Diovan is used to treat high blood pressure (hypertension) in adults and children who are at least 1 year old. Lowering blood pressure may lower your risk of a stroke or heart attack.
Diovan is also used in adults to treat heart failure and lower your risk of needing to be hospitalized, and to lower your risk of death after a heart attack.
