Generic Name: denosumab (den-OH-sue-mab)
Brand Name: Xgeva
Denosumab is used for:
Preventing certain bone-related events in patients who have a certain type of tumor that has spread to the bones (bone metastases). It is also used to treat certain patients with giant-cell tumor of bone that cannot be removed by surgery. It is also used to treat high blood calcium levels in patients with cancer. It may also be used for other conditions as determined by your doctor.
Denosumab is a receptor activator of nuclear factor kappa B ligand (RANKL) inhibitor. It works by slowing bone loss and increasing bone strength. This helps to reduce the risk of bone-related events in patients with cancer that has spread to the bone.

- you are allergic to any ingredient in denosumab
