Eplerenone (eplerenone) — Uses, Dosage, Side Effects & Safety
Drug class: Aldosterone antagonist (Selective Mineralocorticoid Receptor Antagonist)
Overview
Eplerenone is a prescription medication used to treat high blood pressure (hypertension) and heart failure, especially after a heart attack. It helps lower the risk of serious heart complications by blocking the effects of a hormone called aldosterone, which can cause your body to retain salt and water. By reducing fluid buildup and lowering blood pressure, eplerenone helps your heart work more efficiently and reduces the risk of hospitalization for heart failure. It is often used alongside other medications, such as ACE inhibitors or beta-blockers. Key points for patients: Take eplerenone exactly as prescribed, usually once or twice daily. Regular blood tests are needed to monitor potassium and kidney function. Do not use potassium supplements or salt substitutes unless directed by your doctor.
