1. Fatigue or tiredness
One of the most frequently reported effects, especially in the first few weeks.
2. Dizziness or lightheadedness

4. Cold hands and feet
Reduced circulation in extremities is fairly common.
5. Shortness of breath (in some people)
More likely in those with asthma or breathing conditions.
6. Low blood pressure
May cause weakness or feeling faint when standing up.
7. Sleep disturbances
Some people report vivid dreams or difficulty sleeping.
8. Depression or mood changes
Less common, but possible in sensitive individuals.
9. Digestive issues
Such as nausea, diarrhea, or stomach discomfort.
10. Reduced exercise tolerance
You may feel tired or winded more easily during physical activity.
Important Safety Note
Do not stop metoprolol suddenly, as this can cause serious rebound effects like:
- Increased heart rate
- Higher blood pressure
- Chest pain
Always consult your doctor before changing the dose.
When to Seek Medical Help
Contact a healthcare provider if you experience:
- Severe dizziness or fainting
- Very slow heartbeat

- Worsening chest pain
Bottom Line
Metoprolol is effective and generally safe, but side effects like fatigue, dizziness, and slow heart rate are common. Most are manageable, and your doctor can adjust treatment if needed.
