Metoprolol is a commonly prescribed beta-blocker for high blood pressure, heart disease, and certain arrhythmias. Like all medications, it can cause side effects—some mild, some more serious. Here are 10 side effects doctors watch for:
🩺 Common Side Effects
- Fatigue or tiredness – the most frequently reported
- Dizziness or lightheadedness – especially when standing up quickly
- Slow heartbeat (bradycardia) – can cause fainting in rare cases
- Cold hands or feet – due to reduced circulation
- Digestive issues – nausea, diarrhea, or stomach cramps
🩺 Less Common Side Effects
- Sleep disturbances – insomnia or vivid dreams
- Shortness of breath – may worsen asthma or COPD
- Depression or mood changes – rare but documented
🩺 Serious Side Effects (Seek Medical Attention)
- Severe dizziness or fainting – can indicate dangerously low blood pressure
- Heart failure symptoms – swelling in legs/ankles, rapid weight gain, extreme fatigue
⚠️ Important Notes
- Do not stop suddenly—sudden withdrawal can trigger heart attack or arrhythmia.
- Check with your doctor if you have asthma, diabetes, or heart rhythm problems.
- Side effects are often dose-dependent; sometimes lowering the dose helps.
