Summary
Oxymetazoline is an alpha-adrenergic vasoconstrictor and metoprolol is a beta-1 selective blocker. Unopposed alpha stimulation could modestly raise blood pressure or cause reflex bradycardia, but this is unlikely with typical intranasal doses.
What this interaction means in plain words
Metoprolol and Oxymetazoline have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Metoprolol belongs to Cardiovascular; Oxymetazoline belongs to Respiratory.
Why it happens
Opposing adrenergic pharmacodynamics, with minimal systemic absorption of topical oxymetazoline.
What to do
No action beyond awareness is usually needed; monitor blood pressure and heart rate if oxymetazoline is overused.
