Vincristine Sulfate Injection

Print Friendly, PDF & Email

Generic Name: vincristine sulfate
Product Name: Vincristine Sulfate Injection

Indication: What vincristine sulfate is used for

Vincristine sulfate belongs to a group of anticancer medicines called Vinca alkaloids. It is used for the treatment of various cancers. Vincristine stops the cancer cells from growing and eventually kills them.

Action: How vincristine sulfate works

The precise mechanism of action of vincristine sulfate remains under investigation. Vincristine appears to affect cell mitosis by interfering with microtubular proteins and causing an arrest of cell division during the metaphase. It is cell cycle phase specific.

Vincristine Sulfate Injection contains vincristine sulfate, mannitol and water for injections. It does not contain a preservative.

Dose advice: How to use vincristine sulfate

Before you are given Vincristine Sulfate Injection

When you must not be given it

Do not use Vincristine Sulfate Injection if:

  • You have an allergy to vincristine or any of the ingredients listed here;
  • You have an allergy to any of the Vinca Alkaloid medicines e.g. Vinblastine and Vindesine;
  • You suffer from Charcot-Marie-Tooth syndrome. This is a type of hereditary nerve disease;
  • You are receiving or have received radiation therapy.

If you are not sure whether any of these apply to you, check with your doctor.

Before you are given it

Tell your doctor if:

  • You have any allergies to:
    • Any other medicine;
    • Any other substances, such as foods, preservatives or dyes;
  • You are pregnant or intend to become pregnant;
  • You are breastfeeding or plan to breastfeed;
  • You have or have had any medical conditions, especially the following:
    • Gout;
    • Kidney stones;
    • Any infections;
    • Liver disease or jaundice;
    • Nerve or muscle disease.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and vincristine may interfere with each other. These include:

  • Medicines to treat gout e.g. allopurinol;
  • Medicines to treat fungal infections e.g. itraconazole and voriconazole;
  • Heart medicines e.g. nifedipine;
  • Phenytoin, a medicine used to prevent seizures, fits or epilepsy;
  • Vaccines;
  • Medicines used to treat infections e.g. isoniazid, ciprofloxacin, norfloxacin and ofloxacin;
  • Any other anti-cancer medicines e.g. methotrexate, doxorubicin, asparaginase and mitomycin-C.

In some cases, two different medicines may be used together by your doctor even if an interaction might occur. In these cases, your doctor may change your dose.

Do not have any vaccinations (immunisations) without your doctor’s approval while you are being treated with vincristine, and for up to 12 months after you stop treatment with it. Vincristine may lower your body’s resistance to infection and there is a chance that you may get the infection the immunisation is meant to prevent.

In addition, other people living in your household should not take oral polio vaccine (Sabin) since there is a chance they could pass the polio virus on to you.

Your doctor will advise you about continuing to take other medicines while you are receiving Vincristine Sulfate Injection.

How Vincristine Sulfate Injection is given

This medicine is given as a slow injection into a vein. Sometimes, it is diluted and given as a long injection. Vincristine Sulfate Injection must only be given by a doctor or nurse.

Your doctor will decide what dose, how often and how long you will receive it. This depends on your condition and other factors, such as your weight, age, blood tests, how well your liver is working, and whether or not other medicines are being given at the same time.

If you are given too much (overdose)

This rarely happens as Vincristine Sulfate Injection is administered under the care of a highly trained doctor. However, if you are given too much vincristine, you may experience some of the effects listed under “Side Effects” below.

Your doctor has information on how to recognise and treat an overdose. Ask your doctor if you have any concerns.

While you are being given Vincristine Sulfate Injection

Things you must do

Vincristine Sulfate Injection can temporarily lower the number of white blood cells in your blood, increasing the chance of you getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

  • If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection, or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination;
  • Check with your doctor immediately if you notice any unusual bleeding or bruising, black stools, blood in urine or stools or pinpoint red spots on your skin;
  • Be careful when using a regular toothbrush, dental floss or toothpick. Your doctor or nurse may recommend other ways to clean your teeth and gums;
  • Check with your doctor before having any dental work done;
  • Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime;
  • Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters;
  • Avoid contact sports or other situations where bruising or injury could occur;
  • Be sure to keep all of your doctors’ appointments so that your progress can be checked;
  • If you become pregnant while under vincristine treatment, tell your doctor immediately.

Things you must not do

  • Do not have any immunisations or vaccinations without your doctor’s approval and for up to 12 months after you stopped treatment with it.
