Redefine XLH

X-linked hypophosphatemia (XLH) is a disease where the body doesn’t retain enough phosphorus. Phosphorus is important for bone health, and when there is not enough phosphorus, bones can weaken over time.

CRYSVITA can help the body retain a normal amount of phosphorus.

CRYSVITA efficacy and safety have been studied in children and adults with XLH.
