Metoprolol is a beta-blocker commonly prescribed for high blood pressure, chest pain (angina), certain heart rhythm disorders, and heart failure. Like all medications, it can cause side effects, though many people tolerate it well.
10 Common Side Effects of Metoprolol
- Fatigue or tiredness
- One of the most frequently reported side effects.
- Dizziness or lightheadedness
- Especially when standing up quickly due to lowered blood pressure.
- Slow heart rate (bradycardia)
- Metoprolol works by slowing the heart, but sometimes it can slow it too much.
- Cold hands and feet
- Reduced circulation to the extremities can occur.
- Low blood pressure
- May cause weakness, dizziness, or fainting.
- Shortness of breath
- More likely in people with asthma or certain lung conditions.
- Sleep problems
- Some people experience insomnia, vivid dreams, or disturbed sleep.
- Nausea or stomach upset
- Usually mild and often improves over time.
- Depression or mood changes
- Reported by some patients, though not everyone experiences this.
- Reduced exercise tolerance
- You may notice you tire more easily during physical activity.
When to contact a healthcare professional
Seek medical advice if you experience:
- Severe dizziness or fainting
- Very slow heartbeat
- Worsening shortness of breath
- Swelling of the legs
- Chest pain
- Signs of an allergic reaction
Important reminder
Do not stop metoprolol suddenly unless instructed by your healthcare professional. Abruptly stopping it can cause a rapid increase in heart rate, chest pain, or other serious heart-related problems.
Many people experience few or no side effects, and the benefits of the medication often outweigh the risks when it’s prescribed appropriately. If you’re having symptoms that you think may be related to metoprolol, it’s best to discuss them with the clinician who prescribed it.
