plerixafor
Mozobil (plerixafor) is an injectable medication used together with granulocyte-colony stimulating factor (G-CSF) in people diagnosed with non-Hodgkin's lymphoma or multiple myeloma who are planned to have a stem cell transplant. This medication helps move your stem cells from your bone marrow to your blood so they can be collected and used for your own transplant. Mozobil (plerixafor) is typically given by a trained healthcare provider at an outpatient clinic.

How Mozobil (plerixafor) works
Mozobil (plerixafor) is a hematopoietic (blood) stem cell mobilizer. It blocks a protein on your stem cells called CXCR4 so that they can't anchor themselves in the bone marrow. This helps release your stem cells from the bone marrow and into the bloodstream, where they're collected for your transplant.
