Pediatric allergic cough, as the name implies, is a cough caused by exposure to allergens, most commonly cough variant asthma, which is a specific form of asthma. Once it is clear that the cough is caused by allergies, it must be treated aggressively as soon as possible. First of all, it is important to identify the allergen and avoid contact with all kinds of allergens, and if necessary, have an allergen test. Secondly, anti-allergy medications can be given to the child, commonly used are desloratadine. Children with cough variant asthma have varying degrees of airway hyperreactivity, so it is very important to improve airway hyperreactivity. It is recommended to give the child chewable tablets of montelukast and, if necessary, choose the glucocorticoid budesonide for nebulized inhalation. Allergic cough and the environment have a lot to do with each other, so it is important to actively improve the living environment. Children with allergic cough generally have a weak constitution, so it is important to actively exercise, get more sunlight, feed reasonably, and strengthen their constitution. You can take some Chinese medicine to strengthen your constitution, or you can take some drugs to enhance your body’s resistance for supplementary treatment, which are very helpful for the recovery of allergic cough. Therefore, when a child has a long-term cough that is not well treated with antibiotics and other organic diseases are ruled out, it is important to think about whether the child has a cough caused by allergies, and once the diagnosis is confirmed, active treatment should be carried out to help the baby’s cough.
