Uses of This Medicine
Spironolactone is used in combination with other medicines to treat high blood pressure (hypertension) and heart failure. Lowering blood pressure can reduce the risk of strokes and heart attacks.
Spironolactone is also used to diagnose and treat hyperaldosteronism, a condition in which the adrenal gland produces too much hormone called aldosterone. This medicine may also be used to treat fluid retention (edema) in patients with congestive heart failure, liver cirrhosis, or a kidney disorder called nephrotic syndrome.
Spironolactone is a potassium-sparing diuretic (water pill). It prevents your body from absorbing too much salt and keeps your potassium levels from getting too low. This medicine is also used to treat or prevent hypokalemia (low potassium levels in the blood).
This medicine is available only with your doctor’s prescription.
