Compare FAA documents: olopatadine nasal sprayWhat each of the two FAA documents says, in plain wordsOpen

The FAA's documents differ. The FAA's allergy sheet gives olopatadine nasal spray a longer initial ground trial of 7 days; the FAA's MedGuide, newer, gives it 48 hours after the first dose. Both are current FAA documents and both name the medicine, so neither is set aside.

Wait

  • 7-day ground trial when starting (the FAA's allergy sheet)

The FAA's MedGuide names olopatadine nasal spray (Patanase) 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.

The FAA's allergy sheet lists olopatadine nasal spray as acceptable allergy medication, which may be used as a single agent or in any combination product, if other certification criteria are met, and says it requires a longer initial ground trial of 7 days. Under new medications, the allergy sheet 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 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.
