Diovan belongs to a family of medications known as angiotensin II receptor blockers. Its main component is valsartan. It is used to treat high blood pressure (hypertension). Valsartan is also used to treat chronic heart failure or to reduce the risk of death after a heart attack in people who cannot use another type of medication called angiotensin-converting enzyme inhibitor. Valsartan blocks the action of angiotensin II, resulting in the relaxation of the blood vessels. This relaxation causes the blood pressure to drop. Valsartan may be used alone or in combination with a diuretic.
Take Diovan exactly as prescribed by your doctor. To treat high blood pressure, the recommended adult dose is 80 mg once daily. To treat heart failure, the recommended starting dose is 40 mg twice daily. The maximum recommended dose is 160 mg twice daily. After a heart attack, the recommended starting dose of valsartan is 20 mg twice daily. Your doctor may increase the dose slowly over 1 to 2 weeks to a target dosage of 160 mg twice daily.
Before taking Diovan you should talk with your doctor if you have kidney or liver problems, low blood pressure, congestive heart failure, glaucoma, if you are allergic to sulfa drugs or penicillin, breastfeeding. Avoid drinking alcohol. It can lower your blood pressure and may increase some of the side effects.
Do not take Diovan if you are allergic to valsartan or to any of the ingredients of the medication, or pregnant.
