Summary
Oxymetazoline constricts nasal blood vessels and may slow absorption of other intranasal products. The extent of absorption is not meaningfully changed, so the effect on azelastine-fluticasone is minor.
What this interaction means in plain words
Azelastine-fluticasone 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 delays the rate of mucosal absorption of coadministered nasal drugs.
What to do
Give the oxymetazoline a few minutes before or after the azelastine-fluticasone spray if both are needed. Limit oxymetazoline to a few days to avoid rebound congestion.
