Here are 10 worth knowing:
Tiredness or weakness — especially when starting treatment or increasing the dose.
Dizziness or light-headedness — metoprolol can lower blood pressure and slow the heart rate.
Slow heartbeat (bradycardia) — an excessively slow pulse can become a problem.
Low blood pressure — may cause dizziness, weakness, or fainting.
Cold hands or feet — reduced peripheral circulation can make your extremities feel unusually cold.
Sleep problems or nightmares — these have been reported with metoprolol.
Depression or mood changes — depression is a reported adverse effect.
Shortness of breath or wheezing — particularly important in people with asthma or other breathing disorders.
Diarrhea, nausea, or stomach discomfort — gastrointestinal symptoms can occur.
Confusion or short-term memory problems — these have been reported, although such symptoms can have many other causes.

🚨 Symptoms that shouldn’t be ignored
Contact a healthcare professional promptly if you develop fainting, significant dizziness, worsening shortness of breath, swelling of the legs, or an irregular heartbeat. New or persistent chest pain or severe breathing difficulty requires urgent medical attention.

Don’t make this mistake
Never stop metoprolol abruptly on your own. Sudden withdrawal can worsen angina and may increase the risk of serious cardiac problems. Your doctor should supervise any dose reduction.

Also tell your doctor or pharmacist about your other medicines. Metoprolol can interact with some blood-pressure medicines, certain heart medicines, NSAIDs such as ibuprofen, and diabetes medications. It can also make some warning symptoms of low blood sugar less noticeable.

Bottom line: Metoprolol can cause side effects, but experiencing one doesn’t automatically mean the medication is unsafe for you. Persistent or troublesome symptoms should be discussed with your doctor or pharmacist rather than prompting you to stop the medicine yourself.
