Avalide is a combination medication that’s used to treat high blood pressure.

Avalide is a combination of irbesartan and hydrochlorothiazide. Irbesartan is an angiotensin II receptor blocker (ARB), which blocks a chemical that tightens your blood vessels. This causes your blood vessels to relax and allows more blood and oxygen to reach the heart and other parts of your body.
Hydrochlorothiazide is a thiazide diuretic (water pill) that makes you urinate more. It lowers blood pressure by working in your kidneys to get rid of extra water and electrolytes, like sodium, chloride, and potassium.

Avalide is typically taken by mouth once daily.
