What is this medication?
Xgeva is a monoclonal antibody. Monoclonal antibodies are made to target and destroy only certain cells in the body. This may help to protect healthy cells from damage.
The Xgeva brand of denosumab is used to prevent bone fractures and other skeletal conditions in people with multiple myeloma, and in people with tumors that have spread to the bone.
Xgeva is also used to treat giant cell bone tumor in adults and teenagers with fully matured bone structure.
Xgeva is also used to treat high blood levels of calcium caused by cancer, when other medicines such as pamidronate or zoledronic acid (Zometa) have been used without success.
Prolia is another brand of denosumab used to treat osteoporosis in postmenopausal women who have high risk of bone fracture
