Plerixafor Injection


Plerixafor injection is used along with a granulocyte-colony stimulating factor (G-CSF) medication such as filgrastim (Neupogen) or pegfilgrastim (Neulasta) to prepare the blood for an autologous stem cell transplant (procedure in which certain blood cells are removed from the body and then returned to the body after chemotherapy and/or radiation) in patients with non-Hodgkin’s lymphoma (NHL; cancer that begins in a type of white blood cells that normally fights infection) or multiple myeloma (a type of cancer of the bone marrow). Plerixafor injection is in a class of medications called hematopoeitic stem cell mobilizers. It works by causing certain blood cells to move from the bone marrow to the blood so that they can be removed for transplant.

Dosage Of Plerixafor Injection

Plerixafor injection comes as a liquid to be injected subcutaneously (under the skin) by a doctor or nurse in a medical facility. It is usually injected once a day, 11 hours before the removal of blood cells, for up to 4 days in a row. Your treatment will begin after you have received a G-CSF medication once a day for 4 days, and you will continue to receive the G-CSF medication during your treatment with plerixafor injection.


Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body’s response to plerixafor injection.

Ask your pharmacist any questions you have about plerixafor injection.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
