If you’re looking for a reliable guide, the headline is a little misleading: there isn’t one universal list of “10 most common” side effects, and the effects vary somewhat between metoprolol tartrate and metoprolol succinate.
10 effects to know about
- Tiredness or fatigue
- Dizziness or lightheadedness
- Slow heartbeat
- Low blood pressure
- Shortness of breath
- Diarrhea
- Depression or mood changes
- Rash or itching
- Dry mouth
- Sleep disturbances or other nervous-system effects
Tiredness, dizziness, depression, diarrhea, shortness of breath, slow heart rate, and rash are specifically listed among common adverse reactions in prescribing information. MedlinePlus also lists dizziness, tiredness, diarrhea, dry mouth, and rash/itching among side effects. (MedlinePlus)
⚠️ Don’t stop metoprolol suddenly
Stopping metoprolol abruptly can cause serious heart problems, so don’t change the dose or discontinue it without discussing it with your doctor. (MedlinePlus)
Seek prompt medical attention for difficulty breathing, fainting, significant swelling, unexpected weight gain, or a rapid/pounding/irregular heartbeat. (MedlinePlus)
If you’re taking metoprolol and experiencing a particular symptom, tell me the dose, whether it’s tartrate or succinate, and the symptom, and I can explain how likely it is to be related.
