Vincristine Sulfate

The recommended dose and dosing schedule of vincristine varies according to the specific type of cancer being treated, the response to therapy, and the other drugs or treatments being used. The dose administered is also based on body size.

Vincristine is injected into a vein through a specially prepared site on your skin that has been prepared for this purpose. Very careful handling of Vincristine Sulfate is required. It is always given under the supervision of a doctor in a hospital or similar setting with access to sterile equipment for preparation.

As well as interfering with the genetic material DNA of cancer cells, vincristine can interfere with some of your normal cells. This can cause a number of side effects such as hair loss. Vincristine sometimes causes mild nausea and vomiting, but it is important to keep using Vincristine Sulfate even if you feel ill.

Your doctor, nurse, or pharmacist can advise you on how to reduce the effects of nausea and vomiting. Your doctor may want you to drink extra fluids while using Vincristine Sulfate to prevent kidney problems. Keep track of any side effects and report them to your doctor as suggested in the section "What side effects are possible with Vincristine Sulfate?"

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Vincristine Sulfate exactly as prescribed by your doctor. If you miss an appointment to receive vincristine, contact your doctor as soon as possible to reschedule your appointment.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Gout and Kidney Stones: Vincristine may increase the levels of uric acid in the body, which can increase the risk for gout or kidney stones for people already at risk of these conditions. Talk to your doctor to find out whether you are at risk.

Infection: As well as killing cancer cells, medications that fight cancer may reduce the number of cells that fight infection in the body (white blood cells). Avoid contact with people with contagious infections and tell your doctor if you begin to notice signs of an infection, such as fever or chills.

Liver function: Liver disease or reduced liver function may cause Vincristine Sulfate to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how Vincristine Sulfate may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Vincristine Sulfate, and whether any special monitoring is needed.

Pregnancy: There is a possibility of birth defect if either partner is using vincristine at the time of conception, or if it is taken during pregnancy. It may also harm the baby in other ways if used during pregnancy. Use effective birth control while being treated with Vincristine Sulfate, and tell the doctor immediately if you become pregnant.

Breast-feeding: It is not known whether vincristine passes into breast milk. Because of the risk of harm to the infant, women should not breast-feed while receiving vincristine.
