Summary
Oxymetazoline vasoconstricts the nasal mucosa and may slow absorption of another intranasal product given at the same time. The extent of absorption is not believed to change, so the clinical effect is small and mainly a delayed onset.
What this interaction means in plain words
Azelastine and Oxymetazoline intranasal 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
Local vasoconstriction by oxymetazoline reduces the rate of mucosal absorption of azelastine.
What to do
Give the two nasal sprays at separate times, for example azelastine first and oxymetazoline several minutes later. Limit oxymetazoline to short courses to avoid rebound congestion.
