The presence of coughing symptoms after the fever is reduced indicates that the cough is caused by a lung infection, or a respiratory infection, so finding the cause of the infection for anti-inflammatory treatment is the most effective and direct way to treat the cough. First of all, blood tests, C-reactive protein and Mycoplasma pneumoniae are needed. In case of Mycoplasma pneumoniae or Chlamydia infection, oral azithromycin is recommended for anti-inflammatory treatment. If a bacterial infection occurs and there is no allergy to cephalosporin, cefixime granules can be taken for treatment. If a viral infection occurs, it is recommended to use busulfan anti-inflammatory oral solution for anti-inflammatory treatment. In addition, for cough symptoms, if it is a dry cough, you can use fenagan cough syrup or compound licorice combination. For coughs with more phlegm, you need to use cough and phlegm-relieving drugs, such as Ambrotero Oral Solution, Ambroxol Hydrochloride or Pulmonary Cough Combination.
