Aldactone flushes excess salt and water from the body and controls high blood pressure. It is used in the diagnosis and treatment of hyperaldosteronism, a condition in which the adrenal gland secretes too much aldosterone (a hormone that regulates the body's salt and potassium levels).
 It is also used in treating other conditions that require the elimination of excess fluid from the body. Learn more about Aldactone Treatment for Oily Skin and more. These conditions include congestive heart failure, high blood pressure, cirrhosis of the liver, kidney disease, and unusually low potassium levels in the blood. When used for high blood pressure, Aldactone can be taken alone or with other high blood pressure medications.
