Metoprolol is a commonly prescribed beta blocker for high blood pressure, angina, heart failure, and certain heart conditions. It can be very beneficial, but side effects are possible. The phrase “overlooked” doesn’t mean these effects are secret—many are documented in the official prescribing information.
1. 😴 Fatigue
Feeling unusually tired or lacking energy is one of the more commonly reported effects.
2. 🌀 Dizziness or lightheadedness
Because metoprolol slows the heart and lowers blood pressure, dizziness can occur, particularly when standing up.
3. ❤️ Slow heartbeat
A slower pulse is an expected effect, but an excessively slow heartbeat can become problematic.
4. 📉 Low blood pressure
Hypotension can cause weakness, dizziness or fainting.
5. 🧠 Sleep or mood changes
Headache, insomnia, nightmares, depression, confusion and short-term memory problems have been reported, although these aren’t experienced by everyone.
6. 🥶 Cold hands and feet
Reduced peripheral circulation can make the extremities feel unusually cold. People with existing peripheral vascular disease may experience worsening circulation symptoms.
7. 💨 Breathing problems
Shortness of breath and, less commonly, wheezing or bronchospasm can occur. People with asthma or other respiratory disease should make sure their prescriber knows about it.
8. 🤢 Digestive problems
Diarrhea is reported relatively often, while nausea, constipation, stomach discomfort, gas and heartburn can also occur.
9. 🧴 Skin reactions
Itching and rash can occur; photosensitivity and worsening of psoriasis have also been reported.
10. 👁️ Less-common effects
Blurred vision, tinnitus, musculoskeletal pain and other less-common reactions have been reported. Their occurrence doesn’t necessarily mean metoprolol is the cause, so persistent symptoms should be discussed with a clinician
