Denosumab injection (Prolia) is used to treat osteoporosis (a condition in which the bones become thin and weak and break easily) in men and in women who have undergone menopause (''change of life;'' end of menstrual periods), who have an increased risk for fractures (broken bones) or who cannot take or did not respond to other medications for osteoporosis. Denosumab injection (Prolia) is also used to treat bone loss in men with prostate cancer and in women with breast cancer who are receiving certain treatments that increase their risk for fractures. Denosumab injection (Xgeva) is used to reduce fractures from certain types of cancer that began in another part of the body but has spread to the bones. Denosumab injection (Xgeva) is also used in adults and some adolescents to treat giant cell tumor of bone (GCTB; a type of bone tumor) that cannot be treated with surgery or if surgery is not possible. Denosumab injection is in a class of medications called RANK ligand inhibitors. It works by decreasing bone breakdown and increasing bone strength and density (thickness).
Denosumab injection comes as a solution (liquid) to be injected subcutaneously (under the skin) in your upper arm, upper thigh, or stomach area. It is usually injected by a doctor or nurse in a medical office or clinic. When denosumab injection (Prolia) is used to treat osteoporosis or to treat bone loss in men with prostate cancer and women with breast cancer, it is usually given once every 6 months. When denosumab injection (Xgeva) is used to reduce fractures from cancer that has spread to the bones, it is usually given once every 4 weeks. When denosumab injection (Xgeva) is used to treat giant cell tumor of bone, it is usually given every 7 days for the first three doses (on day 1, day 8, and day 15) and then once every 4 weeks starting 2 weeks later after the first three doses.
