The article presents the features of the pathogenesis, clinical picture in the combination of acute and allergic rhinitis (AR) in children. The main principles of therapy are discussed. Particular attention is paid to the use of the combined preparation in children; this drug contains dimethindene, which blocks H1-histamine receptors, and a decongestant, α1-adrenergic agonist phenylephrine. A clinical case of AR treatment with phenylephrine hydrochloride+dimethindene in a 9-year-old child is described. At the present stage, the active use of this drug in the form of drops, spray and gel in pediatric otorhinolaryngology is promising.
