Metoprolol is a beta blocker commonly prescribed for high blood pressure, angina, certain abnormal heart rhythms, heart failure, and after a heart attack.
For many people, it works well and causes few problems. But like any medication, metoprolol can cause side effects. Some are mild and manageable, while others deserve prompt medical attention.
One rule matters more than anything else: do not stop metoprolol suddenly unless a healthcare professional tells you to. Abrupt withdrawal can cause a rebound increase in heart rate and blood pressure and may worsen chest pain
