Treatment of allergic rhinitis.
Allergic rhinitis, a common and often debilitating disease marked by rhinorrhea, nasal congestion, nasal itching, and sneezing, is on the increase worldwide. Treatment involves allergen avoidance, pharmacotherapy, and, in selected cases, immunotherapy. This overview describes the characteristics, pathogenesis, and diagnosis of allergic rhinitis. The major contributing allergens of seasonal and perennial allergic rhinitis are identified. Pharmacotherapy is described within the context of treatment guidelines developed by the major asthma and allergy professional organizations. Oral H1 antihistamines are first-line therapy for mild-to-moderate allergic rhinitis. The newer, nonsedating agents are recommended over first-generation antihistamines. Some of the newer oral antihistamines, such as cetirizine, desloratadine, and fexofenadine, have been shown to relieve the symptom of nasal congestion. Intranasal steroids are first-line therapy for patients with more severe symptoms.
