Under new medications, it says symptoms must be controlled without adverse side effects and a mandatory 48-hour ground trial is required after initial use; for acceptable medications, it says the initial observation time is not required (see chart below); and its footnote prohibits flight/safety-related duties after initial use of a new medication until after a 48-hour ground trial and no side effects are noted. The allergy sheet also says airmen who are exhibiting symptoms, regardless of the treatment used, must not fly.

The FAA's MedGuide names azelastine nasal spray (Astepro) as allowed, for allergic rhinitis, with a wait of 48 hours after the first dose and none after later doses or after the final dose, used per label directions or as prescribed. The MedGuide defines allowed as acceptable for use while performing flight or safety-related duties, provided the condition is stable/aeromedically acceptable and no adverse side effects are present.
