Spironolactone is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. It is also used to treat swelling (edema) caused by certain conditions (e.g., congestive heart failure) by removing excess fluid and improving symptoms such as breathing problems. This medication is also used to treat low potassium levels and conditions in which the body is making too much of a natural chemical (aldosterone). Spironolactone is known as a "water pill" (potassium-sparing diuretic).
