Allergic rhinitis is a chronic immunoglobulin E-mediated respiratory response to environmental allergens. It is typically treated with intranasal corticosteroids, followed by antihistamines, mast cell stabilizers, decongestants, leukotriene antagonists, and/or anticholinergics. Allergen immunotherapy can target specific environmental allergies and work to change the response of the patient’s immune system to the allergen. The biological therapies that target circulating free IgE, such as Xolair, may be a promising novel approach to treating the disease. The availability of allergen immunotherapy and the potential of biological therapies with novel mechanisms of action are expanding physicians’ treatment arsenal and fueling competition in the allergic rhinitis therapy market.


  • What patient shares do key therapies and brands garner by line of therapy in newly diagnosed allergic rhinitis patients? What are the quarterly trends in prescribing among recently treated and newly diagnosed allergic rhinitis patients?
  • How have allergen immunotherapies and/or biologics been integrated into the treatment algorithm, and what is their source of business?
  • What percentage of allergic rhinitis patients receive drug therapy within 365 days of diagnosis, and how quickly? What percentage of patients progress to later lines of therapy within 365 days of diagnosis?
  • What percentage of allergic rhinitis patients are treated with monotherapy versus combination therapy? What are the most commonly used combinations?
  • What are the product-level compliance and persistency rates among drug-treated patients?
