OBJECTIVE: To explore the regularity and characteristics of ADR induced by levofloxacin. METHODS: Retrieved from, CHKD of CNKI and Wanfang database, a total of 205 literatures about levofloxacin-induced ADR were collected and analyzed statistically in respect of patients’ gender, age, case history, administration route, clinical manifestation and result of treatment. RESULTS: 483 cases(92.9%) were given levofloxacin intravenously in total of 520 ADR cases. 156 cases were characterized with lesion of skin and its appendants (30.0%), followed by lesion of nervous system (n=133, 25.6%), lesion of cardiovascular system (n=65, 12.5%) and anaphylactic shock (n=45, 8.7%). The earliest ADR occurred within 2 min after administration while the latest occurred in 34 d after administration. 514 cases recovered when drug withdrawal or treatment were taken. However, there were 2 cases of sequelae, 4 cases of death and 62 cases of unexpected serious ADRs. CONCLUSION:ADRs induced by levofloxacin present complicated and various symptoms caused by several factors in which the most serious result in death. Clinical doctors should pay more attention to levofloxacin-induced ADRs.
