Denosumab — Uses, Dosage, Side Effects & Safety
Drug class: Monoclonal antibody
Overview
Denosumab is a prescription medication used to treat bone loss (osteoporosis) in postmenopausal women and men at increased risk of fractures. It is also used to prevent bone complications in patients with certain cancers that have spread to the bone, and to treat giant cell tumor of bone. Denosumab works by blocking a protein called RANK ligand, which is involved in the breakdown of bone. By inhibiting this protein, denosumab helps to strengthen bones and reduce the risk of fractures. Key points for patients: Denosumab is given as an injection under the skin every 6 months (for osteoporosis) or more frequently for cancer-related conditions. It is important to maintain good dental hygiene and inform your doctor about any dental procedures, as denosumab can rarely cause jaw problems. Regular blood tests may be needed to monitor calcium levels.
