Abstract: Objective To remind clinicians of possible adverse reactions of granulocytic myelosuppression induced by meropenem and vancomycin injections in clinical use. Methods One case of severe granulocytic myelosuppression was reported in a patient after cerebral hemorrhage surgery. Correlation analysis of the adverse reactions was conducted to identify the possible drug responsible for the occurrence of granulocytic myelosuppression in the patient. Results The severity of the adverse reactions was grade IV myelosuppression. The patient's condition and concomitant medication were excluded before the cause of severe myelosuppression was determined to be the combined use of antibacterial meropenem and vancomycin injections. The relevance of adverse reactions was evaluated as “probable”. The drug was immediately discontinued and the patient was improved after symptomatic treatment. Conclusion Adverse reactions of grade IV myelosuppression induced by the combined use of antibacterial meropenem and vancomycin injections are rarely reported and should be identified during clinical drug treatment.
