Metoprolol is a beta-blocker commonly prescribed for conditions such as high blood pressure, angina (chest pain), certain heart rhythm problems, and heart failure. Like all medicines, it can cause side effects, although many people take it without serious problems.
10 common side effects of metoprolol
- Tiredness or fatigue
- Feeling more tired than usual is one of the most frequently reported effects.
- Dizziness or lightheadedness
- This can happen, especially when standing up quickly, because blood pressure may be lowered.
- Slow heartbeat (bradycardia)
- Metoprolol reduces heart rate; in some people it may become too slow.
- Cold hands and feet
- Reduced circulation to the extremities can cause a feeling of coldness.
- Low blood pressure
- May cause weakness, dizziness, or faintness.
- Sleep changes
- Some people report insomnia, vivid dreams, or changes in sleep patterns.
- Digestive symptoms
- Nausea, diarrhea, constipation, or stomach discomfort can occur.
- Shortness of breath (in some people)
- This may occur, especially in people with asthma or certain lung conditions.
- Weight changes
- Some people notice changes in weight or appetite while taking beta-blockers.
- Sexual side effects
- Some people experience reduced libido or erectile difficulties.
Contact a healthcare professional if you experience:
- Fainting or severe dizziness
- Very slow heartbeat
- New or worsening shortness of breath
- Swelling of the legs or sudden weight gain
- Chest pain or severe weakness
Important: Do not stop metoprolol suddenly unless instructed by a healthcare professional, because stopping beta-blockers abruptly can worsen some heart conditions.
If you tell me your metoprolol dose (for example 25 mg, 50 mg, 100 mg), why you take it, and what side effect you’re noticing, I can help you understand whether it may be related.
