Drug-Induced Thrombocytopenia

  • Thrombocytopenia is common in critically ill patients and is associated with increased mortality.
  • Up to 25% of critically ill patients will develop thrombocytopenia as a result of a medication, termed drug-induced thrombocytopenia (DIT)
  • Antibiotcs are a common, yet infrequently recognized, cause of DIT.
  • Antibiotics reported to cause DIT include linezolid, vancomycin, trimethoprim/sulfamethoxazole, and the beta-lactams.
  • In fact, piperacillin/tazobactam has been associated with DIT more frequently than any other penicillin.
