Ondansetron-induced aminotransferase level elevation: case report and review of the literature.

Elevation of aminotransferase levels is a rarely reported adverse effect of ondansetron. Increased aminotransferase levels, however, have been observed in patients receiving concurrent cisplatin chemotherapy and ondansetron. We describe a 44-year-old woman with no oncologic history or treatment with chemotherapy who received intravenous ondansetron on three separate occasions in the emergency department and subsequently experienced aminotransferase level abnormalities.
