Aldactone is a medication primarily used in the management of conditions related to heart failure, high blood pressure, and certain cases of hyperaldosteronism. It belongs to a group of medicines called potassium-sparing diuretics, also known as water pills. Aldactone helps to reduce the amount of fluid in the body without causing the loss of potassium, unlike other diuretics. It’s also used for treating conditions like edema (swelling) associated with heart, liver, or kidney disease and for patients with certain hormonal imbalances such as excessive hair growth or acne.
