How does Mobozil work? What will it do for me?

Plerixafor belongs to the class of medications called hematopoietic agents. It is used to help collect stem cells for transplantation to treat non-Hodgkin’s lymphoma and multiple myeloma, which are specific cancers affecting blood cells. When used along with another medication called granulocyte-colony stimulating factor (G-CSF), plerixafor works by increasing the number of blood stem cells in the blood stream so they can be collected and used in stem cell transplant.
