What should you do?
Don’t stop metoprolol suddenly. Abrupt withdrawal can cause serious heart problems, including worsening chest pain or heart complications. Talk with your doctor if side effects are persistent or interfering with daily life; the dose or medication may need adjustment.

Seek prompt medical attention for fainting, significant swelling or sudden weight gain, difficulty breathing, or a rapid/pounding/irregular heartbeat.

One additional point: metoprolol can make some warning symptoms of low blood sugar less noticeable, which is particularly important for people with diabetes.
