10 possible side effects
Tiredness or weakness — one of the more common effects.
Dizziness or lightheadedness — particularly when starting treatment or increasing the dose.
Slow heartbeat (bradycardia) — metoprolol deliberately slows the heart rate, but an excessively slow rate can be problematic.
Low blood pressure — may cause dizziness or fainting.
Headache.
Cold hands and feet — reduced peripheral circulation can make extremities feel cold.
Nausea or vomiting.
Stomach pain or diarrhea.
Shortness of breath or wheezing — particularly important in people susceptible to bronchospasm.
Sleep or mood changes — such as sleep disturbance, nightmares, or depression can occur, although these aren’t among the most common effects.

🚨 When should you contact a doctor?
Seek prompt medical attention for new or worsening shortness of breath, swelling of the legs, an unusually slow or irregular heartbeat, fainting, or chest pain. Severe breathing difficulty or a serious allergic reaction requires emergency care.

One very important warning
Don’t suddenly stop metoprolol on your own. Abrupt discontinuation can worsen some heart conditions and increase the risk of serious cardiac problems, including heart attack. If it needs to be stopped, your clinician will generally reduce it appropriately.

Also, dizziness can be more noticeable with alcohol, so be cautious, especially when first starting metoprolol or after a dose increase.

Bottom line: Metoprolol can cause tiredness, dizziness, slow heart rate, low blood pressure, and cold extremities, but these don’t necessarily mean the medication is harmful. Persistent, severe, or new symptoms deserve a medication review rather than stopping the drug yourself.
