Allergic rhinitis is one of the most common chronic diseases managed by pediatricians. It can result in a significant burden of disease for the patient and their family. This article reviews classification of this condition as well as its pathophysiology, mediated by a Th2 lymphocyte response. Methods of diagnosis via elicitation of a thorough history, focused physical examination, and testing for specific allergen sensitization are discussed. Treatment of this condition is examined, focusing on allergen avoidance and a variety of available pharmacotherapies. Finally, allergen immunotherapy modalities and their potential for disease-modifying effects as well as their potential risks and benefits are outlined. Pediatr Ann. 2019;48(12):e485-e488..
