Allergic cough in children, also known as allergic cough, manifests itself in the form of a chronic irritating dry cough and tickling in the throat. Allergic cough is a chronic cough that occurs when allergic people are exposed to certain triggers. The disease manifests itself in prolonged paroxysmal episodes of irritating dry cough, foreign body sensation in the throat, tickling of the throat and other symptoms. The occurrence of allergic cough is related to genetics, the immune system, and environmental factors. Factors that tend to trigger an attack of allergic cough include cigarette smoke, cooking fumes, irritating gases, air pollution, dust, cold air, pollen or flotsam. The treatment of this disease is mainly to avoid allergy-inducing factors, usually under the guidance of a doctor to regulate the use of glucocorticosteroids such as budesonide, antihistamines such as loratadine, etc., and if necessary, can be added to the leukotriene receptor antagonist such as montelukast treatment. The above medications should be used under the guidance of a physician.
