Diovan is the brand name for valsartan and is available as an oral tablet.

Diovan is available as a 40 mg, 80 mg, 160 mg, and 320 mg oral tablet.

Diovan is an ARB and is used to treat high blood pressure (hypertension), heart failure, and to improve survival after a heart attack.

Diovan is an angiotensin II receptor blocker (ARB). It blocks a chemical that causes blood vessels to tighten. When this chemical is blocked, blood vessels relax, lowering blood pressure and allowing more blood and oxygen to get to your heart and other organs.

Diovan is typically taken as 80 mg to 320 mg by mouth once a day for hypertension or 160 mg twice a day for heart failure or after a heart attack.

Diovan is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects. You should always discuss potential side effects with your physician to ensure the medication is suitable and right for you.
