Sublingual Immunotherapy for the Treatment of Allergic Rhinoconjunctivitis and Asthma

Abstract
Allergic rhinitis affects approximately 20% to 40% of the US population.1 Currently, 2 forms of specific immunotherapy (subcutaneous immunotherapy and sublingual immunotherapy) are used clinically in the United States. Quiz Ref ID Considerable interest has emerged in sublingual immunotherapy, which involves placement of the allergen under the tongue for local absorption to desensitize the allergic individual over an extended treatment period to diminish allergic symptoms. Compared with subcutaneous immunotherapy, sublingual immunotherapy is easy to administer, does not involve administration of injections, and may be administered at home, avoiding the inconvenience of office visits. The opportunity for home-based therapy makes it potentially suitable for use in medically underserved areas.
