Metoprolol is a beta-blocker medicine commonly used for high blood pressure, chest pain (angina), and heart rhythm problems. Like all medicines, it can cause side effects.
⚠️ Common side effects
These are the ones people experience most often:
- 💤 Tiredness or fatigue
- 💤 Dizziness or lightheadedness
- 🐢 Slow heart rate (bradycardia)
- 🧊 Cold hands and feet
- 😴 Sleep problems or vivid dreams
- 🤢 Nausea or stomach upset
🧠 Less common but important side effects
- Low blood pressure (feeling faint)
- Shortness of breath (especially in asthma patients)
- Depression or mood changes
- Reduced exercise tolerance
🚨 Serious side effects (seek medical help)
- Very slow heartbeat or fainting
- Severe breathing difficulty or wheezing
- Swelling of legs/feet (fluid retention)
- Chest pain that worsens
- Allergic reaction (rash, swelling, itching)
⚠️ Important warnings
- Don’t stop metoprolol suddenly — it can cause rebound high blood pressure or chest pain
- Use caution if you have asthma, diabetes, or heart block
- It may mask signs of low blood sugar (important for diabetics)
🧠 Simple summary
Most side effects are mild (fatigue, dizziness), but serious ones are rare and need medical attention.
If you want, I can also explain how long side effects last or how to reduce them safely.
