This product is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.
This product contains 3 medications: olmesartan, amlodipine, and hydrochlorothiazide. Olmesartan is an angiotensin receptor blocker (ARB) and amlodipine is a calcium channel blocker. They both work by relaxing blood vessels so blood can flow more easily. Hydrochlorothiazide is called a "water pill" (diuretic) and causes your body to get rid of extra salt and water by making more urine.
