Cephalosporin can treat bronchitis, but only for bronchitis caused by bacteria. If after routine blood tests and C-reactive protein tests suggest an increase in white blood cells or an increase in C-reactive protein, it can be treated by antibiotics such as cephalosporin. If the bronchitis is caused by atypical pathogenic bacteria, azithromycin is usually more effective. If the results of blood tests do not suggest a bacterial infection, oral cephalosporin treatment is not very effective. For bronchitis, it is also necessary to choose the appropriate cough and phlegm relieving drugs for simultaneous adjunctive treatment according to the symptoms.
