Oral vancomycin-induced rash: case report and review of the literature.
Disseminated rash and pruritus are described in an 82-year-old woman with chronic renal failure following administration of oral vancomycin hydrochloride 125 mg q6h for the treatment of Clostridium difficile colitis. Renal function was estimated to be 0.27 mL/s based on a serum creatinine of 177 mumol/L. After eight days of therapy, she developed a slightly raised maculopapular rash on her legs and torso, which spread to her abdomen and arms with continued treatment. Vancomycin was discontinued and the patient was treated symptomatically. The rash cleared and did not recur. Rechallenge with vancomycin was not initiated. No other changes in medications or initiations of new medications occurred during the time of treatment with vancomycin. The patient denied any previous immunologically mediated reactions to medications. Maculopapular rash is rare secondary to vancomycin administration, particularly after oral administration. Although clinically significant serum concentrations can be obtained in patients treated with oral vancomycin who have concomitant C. difficile colitis and renal failure, there has not been a clear correlation between these concentrations and any reported adverse sequelae. This case supports the possible occurrence of a true allergic reaction secondary to low-dose oral vancomycin administration.
