Metoprolol is a widely used beta-blocker prescribed for high blood pressure, angina, heart rhythm issues, and after heart attacks. It works by slowing the heart rate and reducing the heart’s workload.
Here’s a clear, “no-nonsense” breakdown of its effects and side effects.

- Help with some anxiety-related physical symptoms (like palpitations)
⚠️ The “Bad” – 10 common side effects
