Zytiga Tablet Zytiga (abiraterone) works by reducing androgen production in the body. Androgens are male hormones that can promote tumor growth in the prostate gland.
Zytiga is used together with prednisone to treat prostate cancer that has spread to other parts of the body.
Zytiga is used in men whose prostate cancer cannot be treated with surgery or other medicines.
Zytiga is usually taken once per day while also taking prednisone two times per day. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
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 this medicine on an empty stomach. Do not eat anything for at least 2 hours before you take Zytiga and for at least 1 hour after you have taken the medicine.
Do not crush, chew, or break a tablet. Swallow the tablet whole with a full glass of water.
Your blood pressure will need to be checked often, and you may need frequent blood tests at your doctor's office.
You should not stop using Zytiga or prednisone suddenly. Follow your doctor's instructions about tapering your prednisone dose.
Store at room temperature away from moisture and heat.
