Spironolactone (Aldactone) is a diuretic. It helps you make more urine and to lose excess
water from your body. This medicine is used to treat
high blood pressure, and
edema or swelling from heart, kidney, or
liver disease. It is also used to treat patients who make too much
aldosterone or have
low potassium. It is more popular than comparable drugs. It is available in generic and brand versions. Generic spironolactone is covered by most Medicare and insurance plans, but some pharmacy coupons or cash prices may be lower.
