Denosumab is used in adults to treat osteoporosis or bone loss in people who:

• are at high risk for broken bones; or
• cannot use another osteoporosis medicine or these medicines did not work well.

Denosumab is also used in people who are at high risk for broken bones due to certain medicines or cancer treatments.

Denosumab may also be used for reasons not mentioned in this medication guide.

Denosumab can cause many serious side effects. Call your doctor right away if you have a fever, chills, pain or burning when you urinate, severe stomach pain, cough, shortness of breath, skin problems, numbness or tingling, severe or unusual pain, or dental problems.

You should not receive denosumab if you have very low levels of calcium in your blood (hypocalcemia). Severe low blood calcium can lead to a life-threatening condition, hospitalization, or death. Ask your doctor about this risk.
