title: Case report of vancomycin-induced pancytopenia.
abstract: Vancomycin is the first-line agent for the treatment of bacteremia, endocarditis, pneumonia, cellulitis, and osteomyelitis. Pancytopenia is an uncommon adverse effect of vancomycin therapy, with only a few cases of vancomycin-related neutropenia and pancytopenia described in the literature. We describe a case of a 56-year-old man who was diagnosed with chronic paraspinal abscess and started on intravenous vancomycin. He was re-admitted two weeks later with new-onset pancytopenia. Discontinuation of vancomycin resulted in improved cell counts. Physicians should monitor cell counts in patients who are on long-term intravenous vancomycin.
