[Accidental shortening time of high dose methotrexate infusion: case report and literature review]

Methotrexate (MTX) is a folic acid antagonist used at high-dose intravenously on 24 hours (24h) in the treatment of the acute lymphoblastic leukemia (ALL). To prevent potential toxicity, MTX is usually administered following the application of preventive measures. We report a case of an accidental shortening time for high dose MTX infusion and a literature review of accidental intoxications by the MTX. This case illustrates the importance of the respect of MTX high dose infusion time and the major role played by the therapeutic drug monitoring.
