Vincristine liposome is used to treat a type of blood cancer called Philadelphia chromosome negative acute lymphoblastic leukemia (ALL).

Vincristine liposome is given after at least two other cancer treatments did not work or have stopped working.

Vincristine liposome may also be used for purposes not listed in this medication guide.

You should not use vincristine liposome if you have Charcot-Marie-Tooth syndrome or other conditions that cause damage to myelin (protective covering of the nerves in your brain and spinal cord).

Vincristine liposome is given as an infusion into a vein, usually once a week. A healthcare provider will give you this injection.

vincristine liposome must be given slowly, and the infusion can take at least 1 hour to complete.

Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when vincristine liposome is injected.

Vincristine liposome can cause severe constipation. You may be given medication to prevent constipation while you are receiving this medicine. Use all medications as directed by your doctor.

Avoid constipation by a eating fruits, vegetables, and foods high in fiber. Drink plenty of fluids.

Vincristine liposome can lower your blood cell counts. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results.

Usual Adult Dose for Acute Lymphoblastic Leukemia:

2.25 mg/m2 IV over 1 hour once every 7 days

Use: Philadelphia chromosome-negative (Ph-) acute lymphoblastic leukemia (ALL) in second or greater relapse or whose disease has progressed following 2 or more anti-leukemia therapies. This indication is based on overall response rate. Clinical benefit such as improvement in overall survival has not been verified.

You should not use vincristine liposome if you are allergic to it, or if you have Charcot-Marie-Tooth syndrome or other conditions that cause damage to myelin (protective covering of the nerves in your brain and spinal cord).

Tell your doctor if you have ever had:

• liver disease;

• a nerve-muscle disorder such as myasthenia gravis, ALS (Lou Gehrig's disease), multiple sclerosis, or muscular dystrophy;

• a bowel obstruction called paralytic ileus; or

• peripheral vascular disease such as Raynaud's syndrome.

Vincristine liposome may harm an unborn baby. Use effective birth control to prevent pregnancy, and tell your doctor if you become pregnant.

You should not breastfeed while using vincristine liposome. If you use a breast pump during this time, throw out any milk you collect. Do not feed it to your baby. Follow your doctor's instructions about when you can start breastfeeding again after your treatment ends.

Call your doctor for instructions if you miss an appointment for your vincristine liposome injection.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
