Dizziness, especially when standing up from sitting or lying down (called orthostatic hypotension), is common. This happens because metoprolol can lower blood pressure more than expected in some positions.
You might feel faint or unsteady for a moment. Mayo Clinic lists this among effects to watch for, particularly in the early stages of treatment.
To reduce the risk, rise slowly — sit on the edge of the bed for a few seconds before standing. Staying hydrated also supports better blood pressure stability.
