Dry cough in children may be the initial symptom of respiratory tract infection, acute bronchitis, or allergic cough due to weather changes, cold and wind, or exposure to chemical gases and other allergens. Dry cough can be treated with cefaclor pellets for anti-infection and pediatric cough syrup and dextromethorphan syrup for cough relief. You can also use licorice, peel and loquat leaves to boil water to stop coughing and moisten the lungs. If there are irritating gases or dusts around your child, pay attention to stay away from such substances and keep the living environment clean and hygienic. An air freshener can be placed indoors. Especially for children with sensitive bodies, you should also pay attention to strengthening physical exercise and improving the body’s resistance so that you can prevent recurrent coughs.
