Denosumab belongs to a family of medications known as monoclonal antibodies. Specifically, it inhibits a protein that your body uses to signal for removing old bone tissue. Denosumab works by reducing the amount of bone your body breaks down, making your bones less likely to break.
Denosumab is used to treat osteoporosis for postmenopausal women who have a high risk of fracture or who have not tolerated or responded to other osteoporosis medications. It is also used to increase bone mass in men who have osteoporosis and are at high risk of having a fracture, have a history of osteoporotic fracture, or have not tolerated or responded to other osteoporosis medications.
This medication is also is also used to increase bone mass in women who are being treated with an aromatase inhibitor for breast cancer that has not spread to other parts of the body. It is also used to increase bone mass and reduce fractures in men who have prostate cancer that has not spread to other parts of the body and who are receiving medication to reduce testosterone levels.
Denosumab may also be used to increase bone mass in men and women who are taking or have just started to take glucocorticoids (e.g., prednisone, dexamethasone) for a long period of time.

Latex allergy: The needle cap on the pre-filled syringe contains a latex derivative and should not be handled by people who are allergic to latex.
Severe jawbone problems: Denosumab may cause problems with your upper and or lower jaw. You may be at a higher risk of these problems if you have cancer that has spread to the bones, are taking certain medications (e.g., prednisone, anticancer medications), are having radiation treatments, have poor oral hygiene, or are having a tooth extracted. Your doctor may recommend that you see a dentist before starting this medication. It is important to practice good oral hygiene while taking this medication.
