title: Allergic rhinitis. A useful guide to diagnosis and treatment.
abstract: Patients presenting with typical signs and symptoms of allergic rhinitis may respond to avoidance of allergens and to medications for symptomatic relief. Treatment may include antihistamines, decongestants, cromolyn sodium, and/or topical nasal steroids. Patients whose symptoms are refractory to these therapeutic measures should be referred to an allergist for further evaluation and consideration for possible allergen immunotherapy.
