Metoprolol is a beta-blocker commonly prescribed for conditions such as high blood pressure, angina (chest pain), certain heart rhythm problems, and heart failure. It works by slowing the heart rate and reducing the heart’s workload.
Like all medicines, it can cause side effects. The 10 commonly reported side effects include:
- Tiredness or fatigue
- Feeling more easily exhausted, especially when starting treatment.
- Dizziness or lightheadedness
- Often related to lowered blood pressure or a slower heart rate.
- Slow heartbeat (bradycardia)
- A lower pulse is an intended effect, but an excessively slow rate can be a problem.
- Cold hands and feet
- Reduced circulation to the extremities can occur.
- Sleep changes
- Some people report vivid dreams, trouble sleeping, or changes in sleep patterns.
- Low blood pressure
- May cause weakness, dizziness, or fainting.
- Shortness of breath or reduced exercise tolerance
- Can occur, especially in people with certain lung conditions or when the dose is increased.
- Digestive symptoms
- Nausea, diarrhea, constipation, or stomach discomfort may occur.
- Mood changes
- Some people report feeling depressed or having mood changes, though this is not common.
- Sexual side effects
- Some people experience reduced libido or erectile difficulties.
Contact a healthcare professional promptly if you experience:
- Fainting or severe dizziness
- Very slow heartbeat
- New or worsening shortness of breath
- Chest pain
- Swelling of the legs or sudden weight gain
- Signs of an allergic reaction
Important: Do not stop metoprolol suddenly without medical guidance. Abruptly stopping beta-blockers can worsen chest pain or increase the risk of serious heart problems in some people.
If you take metoprolol, tell me your dose (for example 25 mg, 50 mg, 100 mg), why it was prescribed, and what side effects you’re noticing, and I can help you understand whether they are typical or worth discussing with your doctor.
