## What is CaroSpir?

CaroSpir 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.

CaroSpir is used to treat heart failure, high blood pressure (hypertension), or hypokalemia (low potassium levels in the blood).

CaroSpir also treats fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or a kidney disorder called nephrotic syndrome.

CaroSpir is also 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.

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

## Warnings

You should not use CaroSpir if you Addison's disease, high levels of potassium in your blood, if you are unable to urinate, or if you are also taking eplerenone.
