Objective: To investigate the stability of compatibility of levofloxacin and vitamin C in 8h at room temperature. Methods: The content of levofloxacin, the change of ultraviolet absorption spectrum and its stability in 0 ~ 8h after compatibility were determined by ultraviolet spectrophotometer. Results: There was no significant change in the appearance, content and pH of levofloxacin injection in combination with vitamin C at room temperature within 8 hours. Conclusion: The compatibility of levofloxacin and vitamin C is stable within 8h
