When children have bronchitis, they usually have cough and phlegm, so they can take cough and expectorant medicines. Children can take oral aminoglutethimide solution, which has the effect of expectorant and can stop coughing. If the child can take more bitter medicine, it is recommended to take oral lung power cough combination or compound fresh bamboo liquid to treat the child. In addition, the condition of tracheitis occurs mostly due to infections. There are many causes of infections, such as bacterial infections, viral infections or infections of Mycoplasma pneumoniae or Chlamydia, which may lead to tracheitis. Different anti-inflammatory drugs need to be given orally depending on the type of infection, for example, bacterial infections can be given orally to children with pediatric cefixime pellets. If a viral infection occurs, the child can be treated with pediatric black beetle and fever granules or Pudilan anti-inflammatory oral solution. In case of Mycoplasma pneumoniae or Chlamydia infection, azithromycin can be used for treatment.
