These exacerbations most often appear due to NSAID hypersensitivity reactions rather than NSAID-induced allergic reactions. The antihistamine azelastine, applied as a nasal spray, may be effective for vasomotor rhinitis. Fluticasone propionate or budesonide (both are steroids) in nostril spray form may also be used for symptomatic treatment. The antihistamine cyproheptadine is also effective, probably due to its antiserotonergic effects. A systematic review on non-allergic rhinitis reports improvement of overall function after treatment with capsaicin (the active component of chili

Medications are, however, not sufficient or are associated with side effects in many people. Exposing people to larger and larger amounts of allergen, known as allergen immunotherapy, is often effective. The allergen may be
