The title you shared sounds like a sensationalized headline. Metoprolol is a commonly prescribed beta blocker used for conditions such as high blood pressure, chest pain (angina), certain heart rhythm problems, and heart failure. Like all medicines, it can cause side effects, but the idea that there are “10 side effects your doctor is praying you don’t discover” is misleading.
Common and recognized side effects of metoprolol include:
- Tiredness or fatigue — especially when starting treatment or after dose changes
- Dizziness or lightheadedness — often related to lowered blood pressure
- Slow heartbeat (bradycardia)
- Cold hands and feet — due to reduced circulation to the extremities
- Sleep changes — such as vivid dreams or sleep disturbance in some people
- Low energy or reduced exercise tolerance
- Nausea or stomach upset
- Shortness of breath or wheezing — more concerning, especially in people with asthma or lung disease
- Sexual side effects — such as reduced libido or erectile difficulties in some people
- Mood changes — uncommon, but some people report changes in mood
More serious effects that require medical attention can include:
- Fainting or severe dizziness
- Very slow heartbeat
- New or worsening shortness of breath, swelling, or sudden weight gain (possible heart failure worsening)
- Signs of a serious allergic reaction
Do not stop metoprolol suddenly unless a healthcare professional tells you to. Abruptly stopping it can cause a dangerous increase in heart rate, blood pressure, chest pain, or heart complications in some people.
If you take metoprolol, tell me:
- Your dose (for example, 25 mg, 50 mg, 100 mg)
- Whether it is metoprolol tartrate or metoprolol succinate
- Why it was prescribed (blood pressure, heart rhythm, heart failure, etc.)
- What symptom you’re worried about
…and I can help you sort out whether it may be related.
