Brand Names: Avalide

What is Avalide?

Avalide tablets contain a combination of hydrochlorothiazide and irbesartan. Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention. Irbesartan is an angiotensin II receptor antagonist. Irbesartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Avalide is used to treat high blood pressure (hypertension).

Avalide may also be used for purposes not listed in this medication guide.
