About Diovan (valsartan)

Valsartan is considered an angiotensin receptor blocker, which relaxes blood vessels and causes vasodilation which reduces blood pressure.

Valsartan is used to treat high blood pressure (hypertension) and heart failure. It can also lower the risk of hospitalization and death after a heart attack. Valsartan is available only by prescription. It is available in a generic formulation as well as under different brand names, including Diovan.

Valsartan may be prescribed as a tablet or capsule. It is always important to consult your doctor and follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.

If you're prescribed valsartan, it is important to take it as prescribed by your doctor, in order for the medication to adequately treat and manage your medical issue.
