Improved strategies and new treatment options for allergic rhinitis.

Primary principles relevant to the clinical management of allergic rhinitis include (1) avoidance of allergens and triggering factors, (2) use of appropriate pharmacotherapy, (3) evaluation regarding need for and appropriate use of immunotherapy, and (4) patient education and follow-up. Currently available pharmacotherapeutic options include oral and topical (intranasal) decongestants and corticosteroids, mast cell stabilizers, intranasal anticholinergics, and antihistamines. Future therapeutic options include leukotriene modifiers and anti-IgE antibodies.
