RESUMO
Objective @# To analyze the adverse drug reaction（ADR） reports of hydroxychloroquine for clinical medication safety. @* Methods@#The ADR reports of hydroxychloroquine between May 2019 and May 2021 were analyzed. Age, reasons for drug use, time of ADR, combined drug use, and ADR outcomes were statistically analyzed. @*Results@# No severe ADR was reported. Patients over 60 years old accounted for 53.85% of the total cases, and the time of ADR appearance was significantly earlier among those under 60 years old. A total of 61.54% of ADRs were involved in multiple organs, and optic neurotoxicity was reported in 46.15% of cases. @*Conclusion@# In the treatment of oral lichen planus with hydroxychloroquine, adverse drug reactions should be monitored, and increased attention should be given to patients over 60 years old to ensure the safety of this medication.
