The headline “Metoprolol: The Straight Talk on 10 Side Effects & When to Get Your Doctor’s Attention, ASAP!” is more reasonable than many viral health headlines, although it still uses dramatic wording to attract attention.
Metoprolol is a beta blocker commonly prescribed for high blood pressure, angina, certain heart rhythm problems, heart failure, and after a heart attack. Most people take it without serious problems, but side effects can occur.
Common side effects
- Tiredness or fatigue
- Dizziness, especially when standing up
- Slow heart rate
- Cold hands or feet
- Mild nausea or stomach upset
- Trouble exercising as intensely as usual
Side effects that deserve prompt medical attention
Contact your healthcare professional promptly if you develop:
- Very slow heartbeat, especially if accompanied by dizziness or fainting
- Fainting or severe lightheadedness
- New or worsening shortness of breath, wheezing, or swelling of the legs
- Chest pain that is new or getting worse
- Signs of an allergic reaction, such as swelling of the face, lips, tongue, or difficulty breathing (seek emergency care)
Important reminders
- Do not stop metoprolol suddenly. Abruptly stopping a beta blocker can cause a rebound increase in heart rate and blood pressure and may worsen angina or increase the risk of a heart attack in some people.
- Take it exactly as prescribed and let your healthcare professional know about all other medicines and supplements you use.
Bottom line: Metoprolol can cause side effects, but most are mild and manageable. The key is recognizing symptoms that need medical evaluation and not stopping the medication without medical guidance.
