Metoprolol is a beta blocker commonly prescribed for high blood pressure, angina, certain heart rhythm problems, heart failure, and after a heart attack.
For many people, it is effective and well tolerated. But like all medicines, metoprolol can cause side effects. Some are mild and temporary, while others may need medical attention.
The most important rule is simple: do not stop metoprolol suddenly unless a healthcare professional tells you to, because abrupt withdrawal can worsen chest pain, increase heart rate, and potentially trigger serious heart problems.
