Metoprolol is a commonly used beta-blocker for conditions like high blood pressure, heart rhythm problems, angina, and after heart attacks. Like all medicines, it can cause side effects—some mild, some more serious.
⚕️ Common side effects
These are relatively frequent and often improve as your body adjusts:
- Fatigue or low energy
- Dizziness or lightheadedness
- Slow heart rate
- Cold hands and feet
- Mild shortness of breath (in some people)
- Sleep disturbances or vivid dreams
⚠️ Less common but important
These should be monitored:
- Low blood pressure (feeling faint)
- Depression or mood changes
- Reduced exercise tolerance
- Sexual dysfunction (e.g., reduced libido)
- Swelling of hands/feet
🚨 Serious side effects (seek medical help)
Rare but important:
- Very slow heart rate (bradycardia)
- Severe dizziness or fainting
- Worsening chest pain or heart failure symptoms
- Shortness of breath or wheezing (especially in asthma/COPD patients)
- Allergic reactions (rash, swelling, difficulty breathing)
🧠 Important safety notes
- Don’t stop metoprolol suddenly → can cause rebound fast heart rate or chest pain
- Dose changes should be gradual and supervised
- Caution in people with asthma, diabetes, or low blood pressure
🧾 Bottom line
Metoprolol is generally safe and widely prescribed, but:
- Mild tiredness and dizziness are common
- Serious side effects are uncommon but need attention
- Never stop it suddenly without medical advice
