Allergic rhinitis (AR) occupies a special place among allergic diseases. Allergic rhinitis is a serious medical, social and economic problem.

Prevention, diagnosis, and treatment of allergic rhinitis among children is not only a purely medical but also a social problem. They account for a considerable part of both direct (the cost of drugs, hospital and outpatient care), and indirect (early mortality, disability, payment temporary disability) expenses of the company. They have a significant impact on the quality of patients' life.
