Epidemiologic and pathophysiologic evidence indicates that allergic rhinitis, whether seasonal or perennial, is one piece of a larger atopic clinical picture that often occurs concomitantly with asthma. Allergic rhinitis usually develops during childhood and has a prevalence of up to 40% in the pediatric population. Careful attention to food allergies and the presence of household allergens during infancy and early childhood may limit potential sensitizations. Many antihistamines and topical corticosteroids now are available for the treatment of allergic rhinitis in children, which is all the more important because optimal management may improve quality of life and curtail the development of serious sequelae.
