Aldactone (Spironolactone)

Aldactone is used for treating swelling and fluid retention in patients with congestive heart failure, liver cirrhosis, or kidney problems (nephrotic syndrome). It is also used for treatment of high blood pressure. It may also be used to treat or prevent low blood potassium. It may also be used to treat excess secretion of the hormone aldosterone by the adrenal gland.

Aldactone is a potassium-sparing diuretic. It works by blocking the hormone aldosterone, causing the kidney to eliminate excess water, save potassium, and lower blood pressure.

Do NOT use Aldactone if:

• you are allergic to any ingredient in Aldactone
• you are unable to urinate, have severe kidney problems, or have high blood potassium levels
• you are taking a potassium supplement, another potassium-sparing diuretic (eg, amiloride, triamterene), or another aldosterone-blocker (eg, eplerenone)

• if you are pregnant, planning to become pregnant, or are breast-feeding
• if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
• if you have allergies to medicines, foods, or other substances
• if you have high acidity in your body fluids; low blood sodium levels; high blood potassium levels; kidney, liver, or heart disease; diabetes; or high urea or nitrogen in your blood
• if you have menstrual disease
