Methods A total of 326 ADR cases of children in Haikou Hospital of the Maternity and Child Health from January 2014-December 2019 were collected and analyzed. Results 326 ADR cases were collected and analyzed, 189 cases of which are men, and 137 cases of which are women; 132 cases (40.49%) of children are one year old, 108 cases (33.13%) of children are 1-3 years old, 61 cases (18.71%) of children are 4-6 years old, and 25 cases (7.67%) of children are aged 7-14 years old. There were 195 cases (59.82%) children with ADR occurrence time >48 h; 87 cases (26.69%) children with ADR occurrence time ≤ 48 hours, and 44 cases (13.50%) children with ADR occurrence time ≤ 24 h. Medication pathway:215 cases (65.95%) children were administrated by intravenous, 70 cases (21.47%) children were administrated by oral use, 29 cases (8.90%) children were administrated by intramuscular injection. Original incidence:120 cases (36.81%) children were diagnosed with bronchial pneumonia, 66 cases (20.25%) children were diagnosed with bronchitis, 50 cases (15.34%) children were diagnosed with gastrointestinal infection. The highest clinical performance was 116 cases (35.58%) of digestive system performance, followed by skin and attachment performance of 88 cases (26.99%) and respiratory performance of 43 cases (13.19%). 136 cases (41.72%) ADR were induced by cephalosporine, followed 90 cases (27.61%) ADR were induced by cyclosyl esters, and 76 cases (23.31%) ADR were induced by penicillin. Conclusion ADR occurs mainly in male children, mostly in children under 3 years of age, often occurs at 48 h after administration. Intrtravenous injection is more common medication pathway which induced ADR. The original incidence of children is mainly respiratory disease, and digestive damages are the main manifestation of ADR. The occurrence of ADR are most induced by cephalosporines. Limiting the use of antibiotics and reducing drug administrated by intravenous, ADR had significantly decreased. Clinical use antibiotics should be reasonable to ensure the safety of children's medication."/>
