This product is used to treat high blood pressure (hypertension), heart failure, or extra fluid in the body (edema). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains two medications: amiloride and hydrochlorothiazide. Both medications are "water pills" (diuretics) and cause your body to get rid of extra salt and water. This effect may increase the amount of urine you make when you first start the product. Amiloride also helps to treat or prevent low blood potassium levels.
