What is Diovan?

Diovan is used in adults and in children 1 year of age and older alone or in combination with other medications to treat high blood pressure.

Diovan is also used in adults to treat heart failure (a condition in which the heart is unable to pump enough blood to the rest of the body) and to improve survival after a heart attack.

Diovan belomgs to a class of medications called angiotensin II receptor antagonists. Valsartan works by blocking the action of certain natural substances that tighten the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently.

Warnings

If you have diabetes, do not take Diovan with any medication that contains aliskiren (a blood pressure medicine).

You may also need to avoid taking Diovan with aliskiren if you have kidney disease.

In rare cases, Diovan can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness especially if you also have fever, unusual tiredness, and dark colored urine.

Your dose needs may change if you switch to a different form of valsartan. Avoid medication errors by using only the medicine your doctor prescribes.

Doses are based on weight in children and teenagers. Your child's dose may change if the child gains or loses weight.

It may take 2 to 4 weeks before your blood pressure is under control. If you have high blood pressure, keep using Diovan even if you feel well. High blood pressure often has no symptoms.

Your treatment may also include diet, exercise, lifestyle changes, and other medications. Follow your doctor's instructions very carefully.
