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.
Your doctor will tell you to take supplements of calcium and vitamin D while you are being treated with denosumab injection. Take these supplements exactly as directed.
When denosumab injection (Prolia) is used to treat osteoporosis or bone loss, your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with denosumab injection and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

Unless your doctor tells you otherwise, continue your normal diet.
If you miss an appointment to receive an injection of denosumab, you should call your healthcare provider as soon as possible. The missed dose should be given as soon as it can be rescheduled. When denosumab injection (Prolia) is used for osteoporosis or bone loss, after you receive the missed dose, your next injection should be scheduled 6 months from the date of your last injection.

Denosumab injection may increase the risk that you will break your thigh bone(s) You may feel pain in your hips, groin, or thighs for several weeks or months before the bone(s) break, and you may find that one or both of your thigh bones have broken even though you have not fallen or experienced other trauma. It is unusual for the thigh bone to break in healthy people, but people who have osteoporosis may break this bone even if they do not receive denosumab injection. Denosumab injection may also cause broken bones to heal slowly and may impair bone growth and prevent teeth from coming in properly in children. Talk to your doctor about the risks of receiving denosumab injection.
