How to take ZYTIGA®

Taking Your ZYTIGA® Tablets

ZYTIGA® (abiraterone acetate) is an oral, once-daily medication that you can take at home. ZYTIGA® is a prescription medicine that is used along with prednisone.

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

Follow Your Doctor’s Instructions

Take your prescribed dose of ZYTIGA® one time a day. Your healthcare provider may change your dose, if needed.
Also, take your prednisone exactly how your healthcare provider tells you to.

  • It’s important to take your prescribed dose of ZYTIGA® tablets once daily
  • Swallow ZYTIGA® tablets whole. Do not crush or chew tablets
  • Take ZYTIGA® tablets with water
  • Take ZYTIGA® on an empty stomach, at least 1 hour before or at least 2 hours after a meal
  • 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
  • While taking ZYTIGA®, you will also take prednisone
  • Take your prednisone exactly how your doctor tells you. Do not change or stop taking your prescribed dose of ZYTIGA® or prednisone without talking to your doctor first

Taking Other Medications With ZYTIGA®

Tell your healthcare provider and your pharmacist about all the medicines you take or treatments you receive. It’s important to share information about any other medicines, including prescription and over-the-counter medicines, vitamins, and herbal supplements you are taking.

ZYTIGA® can interact with many other medications.

You should not start or stop any medicine before you talk with the doctor who prescribed ZYTIGA®.

What If You Miss a Dose

If you ever miss a dose of ZYTIGA® or prednisone, take your prescribed dose the following day.

If you miss more than 1 dose of ZYTIGA® or prednisone, tell your doctor right away.

Tips to Help You Stay on Your Treatment Schedule

  • It’s helpful to develop a system or plan to help you take your ZYTIGA® every single day with prednisone and plan ahead for refills.
  • Be sure to plan ahead if you’re going on a trip and will need a refill of your medicine. It’s also a good idea to ask your friends or loved ones to help you keep track of your medications.
