Important: Don’t Stop It Suddenly
If you’ve been taking metoprolol regularly, don’t suddenly stop taking it unless a healthcare professional tells you to. Abruptly stopping a beta-blocker can cause serious heart-related problems in some people.
If you tell me your metoprolol dose (for example, 25 mg or 50 mg), whether it’s metoprolol tartrate or succinate, and which symptom you’re experiencing, I can explain whether that symptom is a known side effect and how concerning it may be.
