Metoprolol is a beta-blocker commonly prescribed for conditions such as high blood pressure, angina (chest pain), heart failure, and certain abnormal heart rhythms. Many people take it without major problems, but side effects can occur.
10 common side effects of metoprolol
- Fatigue or tiredness
- One of the most commonly reported side effects, especially when starting treatment.
- Dizziness or lightheadedness
- May occur because the medication lowers blood pressure.
- Slow heart rate (bradycardia)
- Metoprolol is designed to slow the heart, but in some people it may become too slow.
- Cold hands and feet
- Reduced blood flow to the extremities can make them feel cold.
- Low blood pressure
- This can cause weakness, faintness, or dizziness, particularly when standing up.
- Shortness of breath or wheezing
- This is uncommon but can occur, especially in people with asthma or certain lung conditions.
- Digestive symptoms
- Nausea, diarrhea, constipation, or stomach discomfort may occur.
- Sleep changes
- Some people report insomnia or vivid dreams.
- Depression or mood changes
- Mood-related side effects have been reported but are less common.
- Reduced exercise tolerance
- You may notice that your heart rate does not increase as much during physical activity.
Seek medical care promptly if you develop:
- Fainting or severe dizziness
- Chest pain that is new or worsening
- Difficulty breathing or severe wheezing
- A very slow heart rate with symptoms
- Swelling of the face, lips, tongue, or throat (possible allergic reaction)
Important
- Do not stop metoprolol suddenly. Abruptly stopping it can increase the risk of chest pain, abnormal heart rhythms, or a heart attack. If it needs to be discontinued, your healthcare professional will usually recommend tapering the dose gradually.
If you’re taking metoprolol and experiencing a particular side effect, tell me:
- What dose are you taking?
- What symptom are you having?
- How long have you been taking it?
