Medication safety in oncology: Vincristine

Vincristine, a chemotherapy drug used in the treatment of leukemias, lymphomas, and a variety of solid tumors, may cause nerve toxicity. Despite reports for more than 30 years, "wrong route" errors occasionally occur. If delivered intrathecally (injected into the fluid-filled space around the spinal cord), rather than intravenously, the effects are usually fatal.

The Institute for Safe Medication Practices (ISMP) conducted a survey in 2006 that showed the need for better error reduction strategies. The report included a description of correct procedures and a summary of survey results.

Institute for Safe Medication Practices. Feb. 23, 2006.

The Joint Commission issued a Sentinel Event Alert in July 2005 that included a description of Dana-Farber's protocol for the proper handling and dispensing of vincristine.
