If a 7-month-old child has symptoms of coughing and phlegm, he or she should be taken to the hospital for an auscultation and related tests to determine the cause of the cough and phlegm. If it is caused by tracheal or bronchial infection, it can be treated by taking antibiotics or antiviral medications and medications to stop coughing and reduce phlegm. If the child is not allergic to penicillin, he or she can take amoxicillin granules together with pediatric cough and phlegm granules. If the child is allergic to penicillin, he can take cephalosporins or roxithromycin together with pediatric amoxicillin oral solution for treatment. If the cough and sputum are caused by bronchopneumonia, in addition to antibiotics, the child can be given ultrasonic nebulization to relieve the cough and sputum symptoms. If a child with pneumonia has significant coughing and wheezing, hospitalization is recommended.
