Irbesartan is used for treating high blood pressure. It may be used alone or with other blood pressure medicines.

Generic Avalide is a combination medication used to treat high blood pressure. One component belongs to a class of blood pressure medications that prevents the hormone angiotensin II from constricting the blood vessels, thereby allowing blood to flow more freely and keeping blood pressure down. The other component is a diuretic that increases the output of urine, removing excess fluid from the body and thus lowering blood pressure.
