Metoprolol — Uses, Dosage, Side Effects & Safety

Drug class: Beta-blocker (selective beta-1 adrenergic receptor antagonist)

Overview

Metoprolol is a prescription medication used to treat high blood pressure (hypertension), chest pain (angina), and heart failure. It is also commonly prescribed to help prevent future heart attacks and to control heart rate in certain heart rhythm disorders. Metoprolol works by blocking the action of certain natural chemicals in your body, such as adrenaline, on the heart and blood vessels. This effect lowers heart rate, blood pressure, and strain on the heart. Key points: Metoprolol is usually well tolerated, but it is important to take it exactly as prescribed. Do not stop taking it suddenly without consulting your doctor, as this can worsen heart problems.
