WHY is this medicine prescribed?

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.

HOW should this medicine be used?

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 with plerixafor injection 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.
