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.
This product can rarely cause high potassium levels (hyperkalemia). This effect is more likely to occur in older adults and in patients with kidney disease, diabetes, or a serious illness. Potassium levels must be closely monitored on a regular basis while taking this medication. If not treated, very high potassium levels can sometimes be fatal. Tell your doctor right away if you develop any symptoms of high potassium levels, including muscle weakness, slow/irregular heartbeat, numb/tingling skin.
