Motixafortide Injection

Motixafortide injection is used with filgrastim to help get cells ready for stem cell transplant in patients withmultiple myeloma. Motixafortide is in a class of medications called hematopoietic stem cell mobilizers. It works by increasing the number of stem cells in blood stream to be available for removal as part of the stem cell transplant process.

Motixafortide comes as a solution (liquid) to be given subcutaneously (under the skin). It is usually given by a doctor or nurse 10 to 14 hours before your first stem cell collection. You may receive an additional dose 10 to 14 hours before your third stem cell collection. Your doctor or nurse will monitor you for one hour after you receive your dose.

Your doctor will prescribe you medicines to be taken 30 to 60 minutes before you will receive motixafortide to help reduce the risk of having a reaction to the medication.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
