Summary

Oxymetazoline constricts nasal vessels and may slow the absorption of another nasal product given at the same time. Azelastine may therefore act more slowly or deliver less effectively if the nasal passages are congested or the sprays are used together.

What this interaction means in plain words

Azelastine 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.

Azelastine belongs to Respiratory; Oxymetazoline belongs to Respiratory.

Evidence level: Low

Why it happens

Local vasoconstriction reduces the rate of mucosal absorption of coadministered intranasal drugs.
