Summary
Ozanimod's active metabolites inhibit MAO-B in vitro, which creates a theoretical risk of pressor reactions with sympathomimetics. Intranasal oxymetazoline has low systemic absorption at normal doses, so a clinically important hypertensive effect is unlikely.
What this interaction means in plain words
Oxymetazoline and Ozanimod have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Why it happens
Theoretical additive adrenergic effect from MAO-B inhibition and alpha-agonist absorption.
