What is eplerenone?
Eplerenone is used to lower the risk of death from heart failure after a heart attack.
Eplerenone is also used to treat high blood pressure (hypertension).
Eplerenone may also be used for purposes not listed in this medication guide.
You may not be able to take eplerenone if you have severe kidney disease, high potassium levels in your blood, or type 2 diabetes with increased levels of albumin (a protein) in your urine.
Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact, and some drugs should not be used together.
Before taking this medicine
You may not be able to take this medicine if you are allergic to eplerenone, or if you have:

Some medicines can cause unwanted or dangerous effects when used with eplerenone. Your doctor may change your treatment plan if you also use:

It is not known whether eplerenone will harm an unborn baby. However, having high blood pressure during pregnancy may cause complications such as diabetes or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). Heart failure can get worse during pregnancy and may cause complications such as premature birth. The benefit of treating hypertension or heart failure may outweigh any risks to the baby.
This medicine may affect fertility (ability to have children) in men.
