Frequently asked questions
Can I stop metoprolol suddenly?
No — stopping abruptly can cause a rebound rise in heart rate and blood pressure. Any change must be gradual and doctor-guided.
Why do beta-blockers make me tired?
By slowing the heart they can reduce energy at first; this often settles. Tell your doctor if it persists.
