The easiest and most effective way to relieve dry cough is to take cough medicine, such as Niancian cough syrup, Chuanbei loquat extract, licorice oral liquid, coughing and wheezing oral liquid, lung power cough and other pediatric cough syrup. You should not drink water for half an hour after taking the medicine orally because cough medicine has a local laxative effect in the throat. During the coughing period, the child should take rest and avoid straining, and try not to go to kindergarten. During coughing, it is important to cooperate with dietary treatment. Children should not eat small snacks, snack foods, puffers and other things during coughing, do not eat fried or greasy things, eat light and vegetarian food, and eat seasonal vegetables and fruits. For irritating dry cough, if allergies are considered, anti-allergy medications such as loratadine and cetirizine can be added, and for frequent coughs, nebulization can also be added.
