What is the most important information I should know about spironolactone?

Multum donot

You should not use spironolactone if you have kidney disease, high levels of potassium in your blood, Addison's disease (an adrenal gland disorder), if you are unable to urinate, or if you are also taking eplerenone.

Multum noalcohol

In animal studies, spironolactone caused certain types of cancers or tumors. It is not known whether these effects would occur in people using this medicine. Ask your doctor about your risk.

What is spironolactone?

Spironolactone is a potassium-sparing diuretic (water pill) that prevents your body from absorbing too much salt and keeps your potassium levels from getting too low.

Spironolactone is used to diagnose or treat a condition in which you have too much aldosterone in your body. Aldosterone is a hormone produced by your adrenal glands to help regulate the salt and water balance in your body.

Spironolactone also treats fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or a kidney disorder called nephrotic syndrome. This medication is also used to treat or prevent hypokalemia (low potassium levels in the blood).

Spironolactone may also be used for purposes not listed in this medication guide.

What should I discuss with my doctor before taking spironolactone?

Multum donot

You should not use spironolactone if you are allergic to it, or if you have:

  • kidney disease, or if you are unable to urinate;
  • Addison's disease (an adrenal gland disorder);
  • high levels of potassium in your blood (hyperkalemia); or
  • if you are also taking eplerenone.

To make sure spironolactone is safe for you, tell your doctor if you have:

  • liver disease;
  • heart disease;
  • an electrolyte imbalance (such as low levels of magnesium in your blood); or
  • if you take an NSAID (nonsteroidal-steroidal anti-inflammatory drug), cholestyramine, heparin, lithium, heart or blood pressure medication, potassium supplements, steroid medicine, or another diuretic.

In animal studies, spironolactone caused certain types of tumors, some of which were cancerous. However, very high doses are used in animal studies. It is not known whether these effects would occur in people using regular doses. Ask your doctor about your risk.
