Vincristine, also known as leurocristine and sold under the brand name Oncovin among others, is a chemotherapy medication used to treat a number of types of cancer. This includes acute lymphocytic leukemia, acute myeloid leukemia, Hodgkin lymphoma, neuroblastoma, and small cell lung cancer among others. It is given intravenously.
Most people experience some side effects from vincristine treatment. Commonly it causes a change in sensation, hair loss, constipation, difficulty walking, and headaches. Serious side effects may include neuropathic pain, lung damage, or low white blood cells which increases the risk of infection. Use during pregnancy may result in birth defects. It works by stopping cells from dividing properly. It is vital that it not be given intrathecally, as this may kill.
Vincristine was first isolated in 1961. It is on the World Health Organization's List of Essential Medicines. It is a vinca alkaloid that can be obtained from the Madagascar periwinkle Catharanthus roseus.
