Metoprolol is a beta-blocker commonly prescribed for conditions such as high blood pressure, angina (chest pain), certain heart rhythm problems, and heart failure. Like any medicine, it can cause side effects, although many people take it without serious problems.
10 common side effects of metoprolol
- Tiredness or fatigue
- Because metoprolol slows the heart rate and reduces the heart’s workload, some people feel more tired, especially when starting treatment.
- Dizziness or lightheadedness
- Can occur as blood pressure lowers.
- Slow heartbeat
- A slower pulse is an expected effect, but an unusually low heart rate should be discussed with a healthcare professional.
- Cold hands and feet
- Reduced circulation to the extremities can make some people feel colder.
- Sleep changes
- Some people report vivid dreams or difficulty sleeping.
- Low energy during exercise
- The medication can limit how much the heart rate rises during physical activity.
- Digestive symptoms
- Nausea, diarrhea, constipation, or stomach discomfort can occur.
- Shortness of breath or wheezing (especially in sensitive individuals)
- People with certain lung conditions may need extra caution.
- Sexual side effects
- Some people report changes in sexual function, though this is not experienced by everyone.
- Mood changes
- Some users report changes in mood, though serious effects are uncommon.
Seek medical advice promptly if you experience:
- Fainting or severe dizziness
- Very slow heartbeat
- New or worsening shortness of breath
- Chest pain
- Swelling that is new or worsening
- Signs of an allergic reaction
Do not stop metoprolol suddenly unless your healthcare provider tells you to. Stopping beta-blockers abruptly can worsen certain heart conditions.
If you tell me your metoprolol dose (for example 25 mg, 50 mg, or 100 mg), whether it is tartrate or succinate, and what symptoms you’re noticing, I can help you understand what may be related to the medication.
