Anti-infective treatment with cephalosporins and azithromycin is not always necessary for the treatment of cough. Because of the many causes of cough, only respiratory diseases caused by bacterial infections require anti-infective treatment with antibiotics, for example, in patients with bronchitis and pneumonia, anti-infective treatment with cephalosporins and azithromycin can be used, together with the necessary symptomatic treatment for cough. However, if the cough is caused by Mycobacterium tuberculosis infection, as well as respiratory diseases caused by mycoplasma and chlamydia infections, cephalosporins are not effective at this time. Some coughs caused by non-infectious factors, such as cough variant asthma, upper airway cough syndrome, gastroesophageal reflux cough, and bronchopneumonia, do not require antibiotic anti-sensitivity treatment at this time, and patients mostly require treatment for the cause in concert with cough suppression. Therefore, when a cough occurs, do not blindly use antibiotics to stop the cough. Only coughs with a clear cause and confirmed bacterial infection require anti-sensitivity treatment.
