If the treatment of chronic cough in children is not effective, the following diseases should be considered: mycoplasma infection, interstitial pneumonia, allergic cough (there are many of these coughs and children with allergies should pay attention to them, as this is the season of high incidence), asthma, tuberculosis, etc. Therefore, parents should not assume that antibiotics are sufficient. If the usual antibiotics are not effective, further tests should be performed to clarify the diagnosis early. Chinese medicine is very effective in treating this type of chronic cough, so look for Chinese medicine or a combination of Chinese and Western medicine.
