It is also useful in combination with other chemotherapy drugs to treat Wilm’s tumor (a type of kidney cancer that occurs in children), neuroblastoma (cancer that begins in nerve cells and occurs mainly in children), and rhabdomyosarcoma (cancer that forms in muscles in children).

Vincristine is in a class of vinca alkaloid medications. It works by slowing or stopping the growth of cancer cells in your body. It should only be prepared in intravenous infusion bags as their use in syringes has been discontinued.
