10 Metoprolol Side Effects You Should Know About 💊
Metoprolol is a beta-blocker used for conditions including high blood pressure, angina, certain heart-rhythm problems, and heart failure. Many people tolerate it well, but side effects can occur—especially when starting treatment or changing the dose.
10 possible side effects
- Tiredness or fatigue — one of the more common effects.
- Dizziness or lightheadedness — particularly when standing up quickly.
- Slow heartbeat — metoprolol lowers heart rate as part of its effect.
- Cold hands or feet.
- Headache.
- Nausea or stomach discomfort.
- Sleep disturbances or unusual dreams.
- Low blood pressure, which can cause weakness or dizziness.
- Shortness of breath or wheezing — more concerning in people with asthma or certain lung conditions.
- Sexual difficulties or reduced libido — these can occur in some people.
🚨 When to seek medical help
Contact a healthcare professional if you develop fainting, a very slow or irregular heartbeat, worsening shortness of breath, significant swelling, or symptoms that are severe or persistent.
Don’t stop metoprolol suddenly on your own. Abrupt withdrawal can cause a dangerous increase in heart rate or blood pressure and may worsen angina or other heart problems. Your prescriber can advise you if the dose needs to be reduced gradually.
If you’re taking metoprolol and tell me which side effect you’re experiencing and your dose, I can explain whether it’s a recognized effect and what questions to discuss with your doctor.
