Vincristine is a chemotherapy drug. It is a treatment for various types of cancer including
- Breast cancer
- Lung cancer
- Non Hodgkin lymphoma (NHL)
- Hodgkin lymphoma
- Multiple myeloma
- Head and neck cancers
- Soft tissue sarcoma
- Brain tumours
Vincristine belongs to the group of drugs called vinca alkaloids. These are often called plant alkaloids because the first of these drugs was developed from the periwinkle plant (vinca). These drugs are sometimes called microtubule inhibitors. This describes the way they work in damaging cancer cells. Vincristine works by stopping the cancer cells from separating into two new cells. So it blocks the growth of the cancer.
You have vincristine into your bloodstream (intravenously). You can have it through a thin, short tube (a cannula) put into a vein in your arm each time you have treatment. Or you may have it through a central line, a portacath, or a PICC line. These are long, plastic tubes that give the drugs directly into a large vein in your chest. You have the tube put in before or during your course of treatment and it stays in place as long as you need it.
You can read our information about having chemotherapy into a vein.
You usually have vincristine chemotherapy once a week. The treatment plan depends on which cancer you have.
You have blood tests before starting treatment and regularly during your treatment. The tests check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.

Pregnancy and contraception
This drug may harm a baby developing in the womb. It is important not to become pregnant or father a child while you are having treatment and for a few months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.
Don't breastfeed during this treatment because the drug may come through in the breast milk.
You should not have immunisations with live vaccines while you are having chemotherapy or for at least 6 months afterwards. In the UK, these include rubella, mumps, measles (usually given together as MMR), BCG, yellow fever and Zostavax (shingles vaccine).
You can have other vaccines, but they may not give you as much protection as usual until your immune system has fully recovered from your chemotherapy. It is safe to have the flu vaccine.
It is safe for you to be in contact with other people who've had live vaccines as injections. There can be problems with vaccines you take by mouth (oral vaccines), but not many people in the UK have these now. So there is usually no problem in being with any baby or child who has recently had any vaccination in the UK. You might need to make sure that you aren't in contact with anyone who has had oral polio, cholera or typhoid vaccination recently, particularly if you live abroad.
