Xofigo (zo-FEEG-oh) is an intravenous (IV) injection of the radioactive material radium-223. It is used to treat prostate cancer that is resistant to medical or surgical treatments that lower testosterone and has spread to your bones with symptoms, but not to other parts of your body. The medical term for this condition is metastatic castration-resistant prostate cancer. Xofigo binds with minerals in the bone to deliver radiation directly to bone tumors, limiting the damage to the surrounding normal tissues.

Xofigo is given as an outpatient visit injection into a vein, once a month, usually for 6 months. The injection of Xofigo only takes 1 minute and your entire monthly appointment lasts 30-60 minutes. During your 6 month series of injections, our staff will monitor your blood levels and adjust your dosing schedule if needed. Additional information on Xofigo can be found at the following link:
