Metoprolol is a beta blocker commonly used to treat high blood pressure, angina, heart rhythm disorders, heart failure, and to reduce the risk of future heart problems after a heart attack.
Many people take metoprolol without major issues, but side effects can occur. Here are 10 common side effects:
1. Fatigue or Tiredness
Because metoprolol slows the heart and reduces its workload, some people feel more tired, especially when starting treatment.
2. Dizziness or Lightheadedness
This may happen when standing up quickly due to lowered blood pressure.
3. Slow Heart Rate (Bradycardia)
A slower pulse is expected, but an excessively slow heart rate can cause symptoms.
4. Cold Hands and Feet
Reduced circulation to the extremities can make hands and feet feel colder than usual.
5. Low Blood Pressure
This may cause weakness, dizziness, or faintness.
6. Shortness of Breath
While uncommon, some people—especially those with asthma or other lung conditions—may notice breathing difficulties.
7. Sleep Problems
Insomnia, vivid dreams, or disturbed sleep can occur in some individuals.
8. Digestive Symptoms
Nausea, stomach discomfort, diarrhea, or constipation may occur.
9. Depression or Mood Changes
Some people report feeling down or experiencing mood changes while taking beta blockers.
10. Sexual Side Effects
Reduced libido or erectile difficulties can occur in some patients.
When to Contact Your Doctor
Seek medical advice if you experience:
- Very slow heart rate
- Fainting or near-fainting
- Severe dizziness
- Worsening shortness of breath
- Swelling of the legs
- New or worsening chest pain
Important
Do not stop metoprolol suddenly unless instructed by your healthcare provider. Abruptly stopping a beta blocker can lead to a rapid increase in heart rate and blood pressure and may worsen heart conditions.
If you tell me your metoprolol dose (for example, 25 mg, 50 mg, or 100 mg) and why you’re taking it, I can explain which side effects are most likely and which ones usually improve with time.
