Denosumab is used to treat bone problems that may occur with cancer that has spread to the bones. It may also be used by adults (and teenagers who have reached their final adult height) to treat a certain disease called giant cell tumor of the bone, if they cannot use surgery to treat the disease. It works to prevent bone fractures by slowing the breakdown of your bones by cancer. It should not be used in people with multiple myeloma.
This medication is given by injection under your skin in the upper arm, upper thigh, or abdomen by a healthcare professional as directed by your doctor, usually every 4 weeks. If you are using this medication to treat giant cell tumor of the bone, your doctor may also direct you to receive a dose once a week during the first 2 weeks of treatment.
Use this medication regularly in order to get the most benefit from it. Remember to receive it every 4 weeks. It may help to mark your calendar with a reminder.
