Denosumab is used to treat bone loss (osteoporosis) in women who are at high risk for bone fracture after menopause. It is also used to treat bone loss in men who are at high risk for bone fracture. Osteoporosis causes bones to become thinner and break more easily. Your chance of developing osteoporosis increases after menopause (in women), as you age, if someone in your family has osteoporosis, or if you take corticosteroid medications (such as prednisone) for long periods.
Denosumab is also used to treat bone loss in women who are at high risk for bone fracture while receiving certain treatments for breast cancer.
Denosumab is also used to treat bone loss in men who are at high risk of bone fracture while receiving certain treatments for prostate cancer that has not spread to other parts of the body.
This medication works by slowing bone loss to help maintain strong bones and reduce the risk of broken bones (fractures). Denosumab belongs to a class of drugs called monoclonal antibodies. It prevents certain cells in the body (osteoclasts) from breaking down bone.
Use this medication regularly in order to get the most benefit from it. It is important to keep receiving this medication even if you feel well. Most people with osteoporosis do not have symptoms. Remember to receive it every 6 months. It may help to mark your calendar with a reminder.
Continue to take other medications for your condition as directed by your doctor.
