Metoprolol is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. A lower blood pressure can reduce the risk of strokes and heart attacks.

Metoprolol is also used to treat severe chest pain (angina) and lowers the risk of repeated heart attacks. It is given to people who have already had a heart attack. In addition, metoprolol is used to treat patients with heart failure.

This medicine is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart.

This medicine is available only with your doctor's prescription.
