Hydrochlorothiazide, HCTZ; Irbesartan tablets
What do irbesartan-hydrochlorothiazide tablets do?
IRBESARTAN-HYDROCHLOROTHIAZIDE (Avalide(R)) is a combination of two drugs used to lower blood pressure. Irbesartan controls high blood pressure (hypertension) by relaxing blood vessels. Hydrochlorothiazide is a diuretic. High blood pressure can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. This medicine does not cure high blood pressure. By lowering blood pressure, irbesartan-hydrochlorothiazide can help reduce your risk of having damage to your kidneys, heart, or other organs.
