Metoprolol is a beta-blocker used for conditions such as high blood pressure, chest pain (angina), certain heart rhythm problems, and heart failure. Many people tolerate it well, but it can cause side effects in some people.
10 Metoprolol Side Effects to Know About
- Tiredness or low energy
- Feeling more fatigued than usual is one of the more common effects, especially when starting treatment.
- Dizziness or lightheadedness
- This can happen as blood pressure and heart rate decrease.
- Slow heartbeat
- Metoprolol is designed to slow the heart rate, but a very slow pulse with weakness, fainting, or dizziness should be checked.
- Cold hands and feet
- Some people notice colder extremities due to changes in circulation.
- Sleep changes
- Some people report vivid dreams, trouble sleeping, or daytime tiredness.
- Mood changes
- Less commonly, people may experience changes in mood or feelings of low mood.
- Sexual side effects
- Some people report reduced sexual desire or erectile difficulties.
- Digestive problems
- Nausea, diarrhea, constipation, or stomach discomfort can occur.
- Breathing problems
- People with asthma or certain lung conditions may notice worsening breathing symptoms and should discuss this with a clinician.
- Masking signs of low blood sugar
- In people with diabetes, metoprolol may hide some warning signs of hypoglycemia, such as a racing heartbeat.
Seek medical advice promptly if you experience:
- Fainting or severe dizziness
- New or worsening chest pain
- Severe shortness of breath
- Swelling of the legs or sudden weight gain
- A very slow or irregular heartbeat
Do not stop metoprolol suddenly without medical guidance, because abruptly stopping beta-blockers can increase the risk of heart-related complications in some people.
If you take metoprolol and want a more personalized discussion, share your dose, whether it is metoprolol tartrate or succinate, why you take it, and any symptoms you’ve noticed.
