Diovan

Generic name: Valsartan

Why is Diovan prescribed?

Diovan belongs to a class of blood pressure medications called angiotensin II receptor antagonists. Diovan works by preventing the hormone angiotensin II from narrowing the blood vessels, which tends to raise blood pressure. Diovan may be prescribed alone or with other blood pressure medications, such as diuretics, that help the body get rid of excess water. Diovan HCT provides just such a combination. It contains Diovan plus the common diuretic hydrochlorothiazide.

Diovan also has a stimulative effect on the heart and is prescribed for heart failure in patients who can't tolerate another type of medication called ACE inhibitors. The drug is also given immediately after a heart attack to reduce the risk of death.

Most important fact about Diovan

You must take Diovan regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Diovan, and you must continue taking it even if you are feeling well. Diovan does not cure high blood pressure; it merely keeps it under control.

How should you take Diovan?

Diovan and Diovan HCT can be taken with or without food. Try to get in the habit of taking the medicine at the same time each day—for example, before or after breakfast. You'll be less likely to forget your dose.

• If you miss a dose...
  Take it as soon as possible. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time.

• Storage instructions...
  Store at room temperature. Keep in a tightly closed container, away from moisture.
