Allergic rhinitis, asthma, and Hymenoptera sensitivity affect approximately 20%, 9%, and 0.66% to 3.3% of adults in the United States, respectively. Various environmental control measures and pharmacologic options are available for symptomatic treatment of allergic rhinitis and allergic asthma. However, allergen-specific immunotherapy is the only form of treatment that alters the natural history of allergic disease.
