What is Crysvita used for?

This medication is used to treat low phosphate levels caused by a certain rare genetic problem (X-linked hypophosphatemia) or by a tumor (tumor-induced osteomalacia). It helps by reducing a hormone in your blood (fibroblast growth factor 23) which increases phosphate levels in your body. Normal phosphate levels are important for the growth and strength of bones, teeth, and muscles. Burosumab belongs to a class of drugs known as monoclonal antibodies.
