How Do I Take ZYTIGA® Tablets?

It's important to take ZYTIGA® plus prednisone exactly as your healthcare provider tells you and to stay on the treatment schedule recommended by your doctor to give ZYTIGA® the best opportunity to work.

ZYTIGA® is an oral, once-daily medication that you can take at home.

  • The recommended dose for ZYTIGA® is 1,000 mg (four 250 mg tablets) administered orally once daily in combination with prednisone (5 mg administered orally twice a day). Your healthcare provider may change your dose if needed.

  • Take ZYTIGA® on an empty stomach. Do not take ZYTIGA® with food. Taking ZYTIGA® with food may cause more of the medicine to be absorbed by the body than is needed and this may cause side effects.

  • No food should be eaten 2 hours before and 1 hour after taking ZYTIGA®.

  • Swallow ZYTIGA® tablets whole. Do not crush or chew tablets.

  • Take ZYTIGA® tablets with water.

  • Do not stop taking your prescribed dose of ZYTIGA® or prednisone without talking with your healthcare provider first.

Why Is It Important That I Take Prednisone with ZYTIGA®?

While taking ZYTIGA® tablets you will also take prednisone. Because of the way ZYTIGA® works, certain side effects may occur. Prednisone may help decrease the occurrence and severity of these side effects. For more information, talk to your doctor.

Take your prednisone exactly as your healthcare provider tells you. Do not stop taking your prescribed dose of ZYTIGA® or prednisone without talking to your healthcare provider first.
