Metoprolol is a beta-blocker commonly prescribed for high blood pressure, angina, heart rhythm disorders, and heart failure. While it’s effective, it can cause side effects. Here are the 10 most common or important side effects to be aware of:
1. Fatigue or Tiredness
- Feeling unusually tired or weak is common, especially when starting the medication.
- Usually improves after your body adjusts.
2. Dizziness or Lightheadedness
- May occur when standing up quickly (orthostatic hypotension).
- Important to rise slowly from sitting or lying down.
3. Slow Heart Rate (Bradycardia)
- Can cause heart rate to drop below normal.
- Symptoms: dizziness, fainting, or shortness of breath.
- Requires medical attention if severe.
4. Cold Hands and Feet
- Reduced blood flow to extremities is common.
- Often mild, but may worsen in cold weather.
5. Gastrointestinal Issues
- Nausea, vomiting, diarrhea, or stomach cramps may occur.
- Taking with food can sometimes reduce these effects.
6. Shortness of Breath or Wheezing
- Especially in people with asthma or COPD.
- Any new or worsening breathing issues require immediate medical attention.
7. Sleep Disturbances
- Insomnia, vivid dreams, or nightmares may happen.
8. Depression or Mood Changes
