Customer FAQ’s



How does vincristine kill cancer cells?

The ability of chemotherapy to kill cancer cells depends on its ability to halt cell division. Usually, the drugs work by damaging the RNA or DNA that tells the cell how to copy itself in division. If the cells are unable to divide, they die.

How do you administer vincristine?

The solution may be injected either directly into a vein or into the tubing of a running intravenous infusion (see Drug Interactions below). Injection of Vincristine Sulfate Injection, USP (vincristine sulfate) should be accomplished within 1 minute. The drug is administered intravenously at weekly intervals.

How does vincristine work in the body?

Vincristine is a chemotherapy drug that belongs to a group of drugs called vinca alkaloids. Vincristine works by stopping the cancer cells from separating into 2 new cells. So, it stops the growth of the cancer.

What are the side effects of vincristine?

Common side effects of vincristine sulfate injection include nausea, vomiting, weight loss, diarrhea, bloating, stomach/abdominal pain or cramps, mouth sores, dizziness, headache, hair loss, constipation, loss of appetite, changes in sense of taste, and numbness and tingling in the hands and feet.

What is vincristine used for?

Vincristine is cancer medication that interferes with the growth of cancer cells and slows their spread in the body. Vincristine is used to treat leukemia, Hodgkin's disease, non-Hodgkin's lymphoma, rhabdomyosarcoma (soft tissue tumors), neuroblastoma (cancer that forms in nerve tissue), and Wilms' tumor.

Does vincristine cause myelosuppression?

Vincristine (VCR) and L-asparaginase (L-ASP) are commonly used to treat canine lymphoma. As single agents, these drugs are not myelosuppressive. However, in combination, VCR and L-ASP cause severe neutropenia in some dogs. Medical records of 147 dogs were reviewed.

How does vincristine affect mitosis?

Effects of vincristine on cell survival, cell cycle progression, and mitotic accumulation in asynchronously growing Sarcoma 180 cells. VCR was found to affect cells in interphase, producing a transient G2 block at all drug concentrations and drug exposure durations studied. VCR did not affect DNA synthesis directly.

Does vincristine cause neuropathy?

Peripheral neuropathy results from some type of damage to the peripheral nerves. Certain chemotherapy drugs can cause peripheral neuropathy such as vinca alkaloids (vincristine), cisplatin, paclitaxel, and the podophyllotoxins (etoposide and tenoposide).

What function of the cell will be disrupted by vincristine?

Vincristine prevents the formation of microtubules in cells. One of the roles of microtubules is to aid in the replication of cells. By disrupting this function, vincristine inhibits cell replication, including the replication of the cancer cells.

Important Safety Information

“This preparation is for intravenous use only. It should be administered by individuals experienced in the administration of vincristine sulfate injection. The intrathecal administration of vincristine sulfate injection (vincristine sulfate) usually results in death. Syringes containing this product should be labeled, using the auxiliary sticker provided, to state “FATAL IF GIVEN INTRATHECALLY. FOR INTRAVENOUS USE ONLY.”
"Extemporaneously prepared syringes containing this product must be packaged in an overwrap which is labeled “DO NOT REMOVE COVERING UNTIL MOMENT OF INJECTION. FATAL IF GIVEN INTRATHECALLY. FOR INTRAVENOUS USE ONLY.”"
"Treatment of patients following intrathecal administration of vincristine sulfate injection has included immediate removal of spinal fluid and flushing with Lactated Ringer's, as well as other solutions and has not prevented ascending paralysis and death. In one case, progressive paralysis in an adult was arrested by the following treatment initiated immediately after the intrathecal injection:"
"1. As much spinal fluid was removed as could be safely done through lumbar access."
"2. The subarachnoid space was flushed with Lactated Ringer's solution infused continuously through a catheter in a cerebral lateral ventricle at the rate of 150 mL/h. The fluid was removed through a lumbar access."
"3. As soon as fresh frozen plasma became available, the fresh frozen plasma, 25 mL, diluted in 1 L of Lactated Ringer's solution was infused through the cerebral ventricular catheter at the rate of 75 mL/h with removal through the lumbar access. The rate of infusion was adjusted to maintain a protein level in the spinal fluid of 150 mg/dL."
"4. Glutamic acid, 10 g, was given intravenously over 24 hours followed by 500 mg 3 times daily by mouth for 1 month or until neurological dysfunction stabilized. The role of glutamic acid in this treatment is not certain and may not be essential."
"Pregnancy Category D - Vincristine sulfate can cause fetal harm when administered to a pregnant woman. When pregnant mice and hamsters were given doses of vincristine sulfate that caused resorption of 23% to 85% of fetuses, fetal malformations were produced in those that survived. Five monkeys were given single doses of vincristine sulfate between days 27 and 34 of their pregnancies; 3 of the fetuses were normal at term, and 2 viable fetuses had grossly evident malformations at term. In several animal species, vincristine sulfate can induce teratogenesis as well as embryo death at doses that are nontoxic to the pregnant animal. There are no adequate and well-controlled studies in pregnant women. If this drug is used during pregnancy or if the patient becomes pregnant while receiving this drug, she should be apprised of the potential hazard to the fetus. Women of child-bearing potential should be advised to avoid becoming pregnant."
