Abstract
Upper airway allergic disease in children refers to chronic non-infectious inflammatory diseases of the upper airway caused by allergic inflammation. These diseases have high prevalences and great harm. Attentions should be paid to the treatment of these diseases. Oral antihistamines play an important role in the treatment of allergic diseases. However, there are many types of antihistamines. How to select appropriate antihistamines according to the age and characteristics of children to treat upper airway allergic diseases is a concern of pediatricians. Therefore, the Pediatric Otorhinolaryngology and Head and Neck Surgery Committee of the Chinese Association for the Promotion of Human Health Science and Technology organized relevant experts to form this consensus, in order to guide the use of oral antihistamines in children with upper airway allergic diseases.
