10 Metoprolol Side Effects You Should Know About
Metoprolol is a commonly prescribed beta blocker. It can be very effective, but like any medication, it can cause side effects. Most people do not experience every side effect, and some symptoms may improve as the body adjusts.
1. Tiredness
Feeling unusually tired or lacking energy is a commonly reported effect.
2. Dizziness or Lightheadedness
Because metoprolol lowers heart rate and blood pressure, some people may feel dizzy, particularly when standing up.
3. Slow Heart Rate
Metoprolol deliberately slows the heart rate. If your heart rate becomes unusually slow or you experience dizziness or fainting, contact your healthcare professional.
4. Cold Hands or Feet
Some people may notice their hands or feet feeling colder than usual.
5. Diarrhea
Digestive changes, including diarrhea, can occur.
6. Dry Mouth
Some people experience a dry mouth while taking metoprolol.
7. Sleep or Mood Changes
Some people report sleep disturbances or other changes while taking beta blockers. Persistent or troubling symptoms should be discussed with a healthcare professional.
8. Shortness of Breath
Breathing difficulty can be a serious symptom, particularly in someone with asthma, certain lung conditions, or heart problems.
9. Swelling or Unexpected Weight Gain
Swelling of the hands, feet, ankles, or lower legs, especially with sudden weight gain, can require prompt medical evaluation.
10. Fainting or Irregular Heartbeat
Fainting or a rapid, pounding, or irregular heartbeat should not be ignored and warrants medical attention.
One Important Warning
Do not suddenly stop taking metoprolol. Abruptly stopping a beta blocker can cause serious heart problems. If you want to stop or change the dose, talk with your doctor first.
Metoprolol can also mask some warning symptoms of low blood sugar, which is particularly important for people taking diabetes medications.
