Elotuzumab injection is used along with lenalidomide (Revlimid) and dexamethasone or along with pomalidomide (Pomalyst) and dexamethasone to treat multiple myeloma (a type of cancer of the bone marrow) that has not improved with treatment or that had improved after treatment with other medications but later returned. Elotuzumab injection is in a class of medications called monoclonal antibodies. It works by helping the body to slow or stop the growth of cancer cells.

Elotuzumab comes as a powder to be mixed with sterile water and given intravenously (into a vein) by a doctor or nurse in a healthcare setting. When used in combination with lenalidomide and dexamethasone it is usually given once every week for the first 2 cycles (each cycle is a 28 day treatment period) and then once every 2 weeks. When used in combination with pomalidomide and dexamethasone it is usually given once a week for the first 2 cycles (each cycle is a 28 day treatment period) and then once every 4 weeks.

A doctor or nurse will watch you closely while you are receiving the infusion and after the infusion to be sure you are not having a serious reaction to the medication.
