Allergic rhinitis, an IgE-mediated disease, is the most common chronic childhood condition and is characterized by nasal sneezing, rhinorrhea, palate and eye itchiness, and congestion. Allergic rhinitis should be diagnosed as early as possible to avoid detrimental effects on the quality of life and comorbid disorders. Treatment initially involves avoidance measures and, when necessary, pharmacotherapy or immunotherapy. Pharmacotherapy generally involves antihistamines or nasal corticosteroids, but other medications such as leukotriene antagonists have demonstrated effectiveness in treating allergic rhinitis symptoms. Immunotherapy generally is reserved for patients unresponsive to therapy or unable to take medications.
