Denosumab injection (Xgeva) is used Denosumab injection is in a class of medications called RANK ligand inhibitors. It works to prevent bone loss by blocking a certain receptor in the body to decrease bone breakdown. It works to treat GCTB by blocking a certain receptor in the tumor cells which slows the tumor growth. It works to treat high calcium levels by decreasing bone breakdown as the breakdown of bones releases calcium.
- To reduce the risk of fractures in people who have multiple myeloma (cancer that begins in the plasma cells and causes bone damage), and in people who have certain types of cancer that began in another part of the body but has spread to the bones.
- In adults and some adolescents to treat giant cell tumor of bone (GCTB; a type of bone tumor) that cannot be treated with surgery.

When denosumab injection (Xgeva) is used to reduce the risk of fractures from multiple myeloma, or 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, or high calcium levels caused by cancer, 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 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.

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.
Denosumab injection may cause other side effects. Call your doctor if you have any unusual problems while receiving this medication.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily.
