For children with allergic cough, who usually have coughing and wheezing, aminoglutethimide hydrochloride oral solution and pediatric cough and wheezing oral solution are commonly used. If the child has a cough with a lot of phlegm due to inflammation, aminoglutethimide oral solution and pediatric phlegm-suppressing cough granules are commonly used, while it is important to drink more water and eat lightly during the cough.
