Should You Change the Time You Take Metoprolol?
Do not change your dosing schedule without checking the instructions for your formulation and speaking with a pharmacist or clinician.

8. Digestive Problems
Metoprolol can sometimes cause gastrointestinal symptoms.
Reported effects may include:
Nausea
Diarrhea
Stomach discomfort
Constipation in some individuals
These effects are often mild, but persistent vomiting or diarrhea can contribute to dehydration, which may increase dizziness and low blood pressure.

Metoprolol is often recommended in a consistent relationship to meals so that absorption remains predictable.
