This medication is used alone or in combination with other medicines to treat high blood pressure. It works by blocking a chemical (aldosterone) in your body which in turn lowers the amount of sodium and water the body retains. Lowering high blood pressure helps prevent strokes, heart attacks and kidney problems. It is also used to treat congestive heart failure following a heart attack.
