This is a very common condition with predominance of seasonal allergic rhinitis. The commonest allergen is grass pollen. Bouts of sneezing, watery eyes and nasal obstruction with their potential complications, including distraction, are of concern to aviation safety. Pollens are few at altitude, and negligible or absent in pressurised cabins because of filtration systems.
From an aeromedical perspective, steroid nasal sprays are preferable for treatment because they do not cause sedation and they act as a preventer. They may however cause nose bleed and the spray should not be directed towards the Little area. They require regular use and take several days to be effective. The use of IM steroids is generally not acceptable and would be a reason to consider the application under the flexibility process.

Other antihistamines must not be used within 48 h prior to flying.
