Allergic rhinitis. A useful guide to diagnosis and treatment.

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.
