Metoprolol (Metoprolol) is a commonly prescribed beta-blocker used for high blood pressure, heart rhythm issues, and heart disease prevention. While it’s effective, some side effects are less talked about, especially the subtle ones that can impact daily life.
Here are 10 Metoprolol side effects that are often overlooked:
1. Fatigue and Low Energy

- Beta-blockers can cross into the brain and affect sleep
4. Mild Dizziness or Lightheadedness

7. Depression or Mood Changes
