Plerixafor Injection 24mg/1.2mL – Uses, Benefits, Dosage, Side Effects & FAQs
Description
Plerixafor Injection 24mg/1.2mL is a prescription medicine used with G-CSF to help mobilize hematopoietic stem cells from the bone marrow into the bloodstream before stem-cell collection. It is mainly used for patients with multiple myeloma or lymphoma who require stem-cell mobilization for autologous transplantation.
What Is Plerixafor Injection?
Plerixafor is a CXCR4 receptor antagonist. It helps release hematopoietic stem cells from the bone marrow into the bloodstream, where they can be collected through apheresis.
The 24mg/1.2mL presentation contains 24mg of plerixafor in 1.2mL solution.
Uses of Plerixafor Injection
Plerixafor may be prescribed for:
Stem-cell mobilization before autologous transplantation.
Patients with multiple myeloma requiring stem-cell collection.
Patients with lymphoma requiring stem-cell collection.
Patients who may not mobilize enough stem cells with G-CSF alone.
Certain pediatric patients, depending on the approved indication and local prescribing information.
Plerixafor is a stem-cell mobilization medicine and is not conventional chemotherapy.
Benefits of Plerixafor
1. Helps Mobilize Stem Cells
Plerixafor helps move hematopoietic stem cells from the bone marrow into circulating blood.
2. Supports Apheresis
Increasing circulating stem cells can help healthcare professionals collect an adequate number of cells during apheresis.
3. Useful for Poor Mobilizers
It may benefit patients who have difficulty achieving sufficient stem-cell mobilization with G-CSF alone.
4. Supports Autologous Transplantation
Collected stem cells can be used for autologous transplantation when clinically indicated.
How Is Plerixafor Used?
Plerixafor is generally administered by subcutaneous injection under specialist medical supervision. It is normally used together with G-CSF.
In commonly used treatment protocols, plerixafor is administered approximately 6–11 hours before stem-cell collection.
Plerixafor Injection Dosage
The dose is determined by the treating physician according to body weight, kidney function, treatment protocol and other patient-specific factors.
A commonly used adult dose is 0.24mg/kg subcutaneously, generally given approximately 6–11 hours before apheresis.
Patients with significant kidney impairment may require dose adjustment.
Important: The 24mg/1.2mL vial is the product strength and does not mean the entire vial should automatically be administered. The healthcare professional must calculate the appropriate dose.
