What NOUMED METOPROLOL is used for
NOUMED METOPROLOL tablets contain the active ingredient metoprolol tartrate.
Metoprolol tartrate belongs to a group of medicines called beta-blockers, which are used to:
- lower high blood pressure (hypertension).
- prevent severe chest pain (angina pectoris).
- prevent heart attack (myocardial infarction) or its complications.
- prevent migraine headaches.
It works by affecting the body’s response to some nerve impulses, especially in the heart. As a result, it decreases the heart’s need for blood and oxygen and therefore reduces the amount of work the heart has to do. It also widens the blood vessels in the body, causing blood pressure to fall.
This medicine is available only with a doctor’s prescription.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is not addictive.
