Severe Neutropenia Following a Prolonged Course of Vancomycin That Progressed to Agranulocytosis with Drug Reexposure.
OBJECTIVE: To report a case of severe neutropenia after discontinuing prolonged treatment with vancomycin that progressed to agranulocytosis with vancomycin reexposure.
CONCLUSIONS: This case demonstrates a serious adverse event potentially associated with vancomycin use, and calls attention to the safety of rechallenging with vancomycin during a possible drug-induced neutropenia.
