Eplerenone is usually taken for heart failure.
It helps to keep your symptoms of heart failure under control and reduce the risk of your heart getting weaker by:
- reducing your blood pressure
- controlling the amount of salt and water in your body
- improving your heart function
It works by blocking the action of a hormone called aldosterone.
Eplerenone comes as tablets and is only available on prescription.
Key facts
- You'll usually take eplerenone once a day, but your doctor may tell you to take it every other day if you get side effects or have any problems with your kidneys.
- Side effects include feeling dizzy, headaches, not being able to sleep, and a cough.
- Taking eplerenone can raise the levels of potassium in your blood. This can cause muscle cramps and diarrhoea. You'll have regular blood tests while you're taking it.
- It's important to keep taking eplerenone even if you feel well. You'll still get the benefits of the medicine.
- If you're on or want to start a low-salt diet, talk to your doctor. Some salt substitutes may increase your potassium levels.
