What is abiraterone?

Abiraterone works by reducing androgen production in the body. Androgens are male hormones that can promote tumor growth in the prostate gland.

Abiraterone is used together with prednisone to treat prostate cancer that has spread to other parts of the body. This medicine is used in men whose prostate cancer cannot be treated with surgery or other medicines.

Abiraterone may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking abiraterone?

You should not use abiraterone if you are allergic to it, or if you have ever had:

  • severe liver disease.

Tell your doctor if you have ever had:

  • liver disease;
  • heart problems;
  • low levels of potassium in your blood; or
  • problems with your adrenal gland or pituitary gland.

Abiraterone is not for use by women or children.

This medicine can harm an unborn baby or cause miscarriage. Abiraterone tablets should not be handled by a woman who is pregnant or who may become pregnant. If this cannot be avoided, the woman should wear latex gloves.

Your prednisone dosage needs may change if you have surgery, are ill, or are under stress. Do not change your medication dose or schedule without your doctor's advice.

Take abiraterone on an empty stomach. Do not eat anything for at least 2 hours before you take abiraterone and for at least 1 hour after you have taken the medicine.

Do not crush, chew, or break an abiraterone tablet. Swallow it whole with a full glass of water.

Your blood pressure will need to be checked often, and you may need frequent blood tests.

You should not stop using abiraterone or prednisone suddenly. Follow your doctor's instructions about tapering your prednisone dose.

Store at room temperature away from moisture and heat.

Skip the missed dose and take the medicine the following day on an empty stomach (no food for at least 2 hours before or 1 hour after you take abiraterone). Do not take two doses at one time.
