One important warning
Don’t stop metoprolol suddenly. Abruptly stopping it can worsen heart problems, and the dose may need to be reduced gradually under medical supervision.

Metoprolol can also interact with medicines such as verapamil, diltiazem, clonidine, and certain CYP2D6 inhibitors, potentially increasing the risk of a slow heart rate or other adverse effects.
