Diovan , medically known as valsartan, is an angiotensin II inhibitor used to treat hypertension (high blood pressure) and heart failure.

It works by easing the tightening of blood vessels throughout the body, which allows the blood vessels to relax and lowers the blood pressure.

Diovan comes as an oral tablet taken once or twice per day, with or without food, as prescribed by your doctor.

The most common side effects from Diovan are headache, dizziness, tiredness, stomach pain, joint pain, back pain and diarrhea. Few patients might also experience hoarseness, trouble breathing or swelling of the eyes, face, tongue, lips, throat, hands, feet, lower legs or ankles.

Diovan is sometimes used to treat other conditions, as determined by your doctor.
