Metoprolol is a medication commonly used to treat high blood pressure, chest pain (angina), certain heart rhythm problems, and heart failure. Like all medicines, it can cause side effects, although many people tolerate it well.
Here are 10 common side effects people may experience while taking metoprolol:
- Tiredness or fatigue
- Feeling more tired than usual, especially when starting treatment.
- Dizziness or lightheadedness
- Often related to a drop in blood pressure, especially when standing up quickly.
- Slow heartbeat (bradycardia)
- Metoprolol lowers heart rate; some people may notice a slower pulse.
- Cold hands and feet
- Reduced circulation to the extremities can cause this sensation.
- Sleep changes or unusual dreams
- Some people report trouble sleeping or vivid dreams.
- Weakness
- A general feeling of reduced energy can occur.
- Nausea or stomach discomfort
- Digestive symptoms may happen, particularly early in treatment.
- Shortness of breath during activity
- Some people may notice reduced exercise tolerance.
- Depressed mood or mood changes
- Less commonly, some people experience changes in mood.
- Sexual side effects
- Some people report decreased libido or erectile difficulties.
Seek medical advice 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
- Severe allergic reactions
Important: Do not stop metoprolol suddenly without medical guidance. Abruptly stopping a beta blocker can worsen heart-related conditions and may increase the risk of serious complications.
If you are taking metoprolol, the dose, reason for taking it (blood pressure, heart rhythm, heart failure, etc.), and your other medications can affect which side effects are most likely.
