Allergen immunotherapy (AIT), the only potential disease-modifying treatment for allergic disease, has been used for more than a century. Hankin et al showed significant reduction in pharmacy, outpatient, and inpatient resources in the 6 months following vs the 6 months preceding AIT in Medicaid-enrolled children with allergic rhinitis (AR). A 2013 analysis showed sustained cost reduction over 18 months in patients with AR treated with AIT compared with matched control subjects not treated with AIT.
