To investigate the efficacy and safety of prolonged azithromycin (PAZM) versus switching to doxycycline (SDXC) in the treatment of macrolide-unresponsive pneumonia (MUMPP) in children. A total of 173 children with MUMPP who were hospitalized in Baoji Central Hospital, from January to December 2023 were selected as subjects. According to the choice of secondary antibiotic after 72 hours of initial macrolide therapy, they were divided into two groups: PAZM and SDXC. The efficacy and adverse drug reactions were compared between the two groups, and the risk factors for refractory pneumonia (RMPP) were analyzed. Compared with the PAZM group, the SDXC group had significantly shorter time to defervescence and time to cough relief, a significantly lower proportion of patients using glucocorticoids, and a significantly higher proportion of patients with lung lesion absorption ( <0.05). No adverse reactions such as liver and kidney function impairment and tooth discoloration were observed in either group. RMPP occurred
