Non-allergic rhinitis is characterized by sporadic or persistent perennial nasal symptoms that do not result from IgE-mediated immunopathologic events. The symptoms can be similar to allergic rhinitis, but with a less prominent nasal itch and conjunctival irritation. Chronic rhinitis symptoms are among the most common problems presenting to physicians. When approaching this problem the diagnostic challenge is to determine the etiology, specifically whether it is allergic, non-allergic, or perhaps an overlap of both conditions. Estimates of the prevalence of allergic rhinitis range from as low as 9% to as high as 42%. In comparison, the prevalence of mixed rhinitis is approximately 26 million, and allergic rhinitis 58 million. Non-allergic rhinitis is often characterized by onset after age 20, female predominance, nasal hyperactivity, perennial symptoms, and nasal eosinophilia in approximately one-third of the population.

Allergic rhinitis is responsible for at least $1.8 billion annually for the direct cost of physician visits and medication expenses, or nearly 2.5 percent Of the $47 billion annual direct cost for respiratory treatment. Moreover, the estimated value of lost productivity to employers and society resulting from allergic rhinitis approaches nearly $3.8 billion annually. In the mid-1990s the resulting total annual cost for allergic rhinitis amounted to $5.6 billion.
