Do not use salt substitutes or potassium supplements while taking eplerenone, unless your doctor has told you to.

To be sure this medication is helping your condition and is not causing harmful effects, your blood pressure will need to be checked on a regular basis. Your potassium levels will also need to be checked with frequent blood tests. Do not miss any scheduled appointments.
