Plerixafor

Plerixafor helps your body make new blood cells before a stem cell transplant, which is often used as part of treatment for lymphoma and myeloma. It is injected by a healthcare professional.

Plerixafor Overview

Updated: 

Plerixafor is a prescription medication 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 – a procedure in which blood cells are removed from your body and then returned to the body after chemotherapy and/or radiation. This type of procedure is often used in patients with non-Hodgkin's lymphoma or multiple myeloma, two types of cancer. Plerixafor 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.

Plerixafor is available as a solution to be injected subcutaneously (under the skin) by a healthcare professional 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 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.

Common side effects of plerixafor include diarrhea, nausea, fatigue, injection site reactions, headache, joint pain, and vomiting.

Plerixafor can also cause dizziness. Do not drive or operate heavy machinery until you know how plerixafor affects you.

Plerixafor and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X – are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Plerixafor falls into category D.

It has been shown that use of plerixafor in pregnant women caused some babies to be born with problems. However, in some serious situations, the benefit of using this medication may be greater than the risk of harm to the baby.

Plerixafor and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if plerixafor crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using plerixafor.
