Metoprolol is a widely used beta-blocker prescribed for conditions like high blood pressure, heart rhythm issues, and angina. Like all medicines, it has possible side effects—but most people tolerate it well, especially at prescribed doses.
Here are the known, medically recognized side effects:
💊 Common side effects (fairly mild)
These happen in some people, especially when starting or adjusting dose:
- Fatigue or tiredness
- Dizziness or lightheadedness
- Slow heart rate (bradycardia)
- Cold hands and feet
- Mild shortness of breath during exertion
🧠 Less common effects
- Sleep disturbances or vivid dreams
- Mild depression or low mood
- Reduced exercise tolerance
- Gastrointestinal upset (nausea, diarrhea)
⚠️ Rare but important effects (need medical attention)
- Very slow heartbeat or fainting
- Wheezing or worsening asthma (important in people with lung disease)

🧠 Important context doctors emphasize

🚨 When to call a doctor
Seek medical advice if you experience:
