What Is Diovan Used For?

Diovan is a medication that helps control high blood pressure and supports heart function in individuals with heart failure.

Primary Uses

Diovan is primarily used to treat high blood pressure and heart failure. It is also prescribed after a heart attack to minimize the risk of further heart damage.

How It Works

Diovan works by blocking the action of a substance in the body that causes blood vessels to constrict, leading to lower blood pressure and improved heart function.

Good to know: Diovan is not considered addictive.
