Zytiga is the brand name for abiraterone acetate. It’s a prescription cancer drug used with prednisone to treat advanced prostate cancer (metastatic castration-resistant disease, and in some settings). It works by blocking androgen production.
Key points:
- How it’s used: Typically 1000 mg once daily, taken on an empty stomach, with prednisone 5 mg twice daily.
- Why it’s given with prednisone: To prevent mineralocorticoid side effects (like high blood pressure, swelling, low potassium).
- Administration tips: Take the 1000 mg dose as directed, usually 4 x 250 mg capsules. Do not take with meals; avoid eating around dose times (check your exact timing with your doctor).
- Common side effects: High blood pressure, low potassium (hypokalemia), fluid retention/edema, fatigue, headache, liver enzyme elevations, diarrhea, vomiting, cough, joint or back pain. Some people may have liver problems or mineralocorticoid excess.
- Monitoring and safety: Your doctor will monitor liver function tests, electrolytes (potassium), blood pressure, and swelling. Tell your doctor if you notice yellowing of the skin/eyes, dark urine, severe fatigue, swelling, or shortness of breath.
- Important interactions: Avoid strong CYP3A4 inhibitors or inducers unless your clinician says so. Inform your healthcare provider about all medicines you take, including supplements.
- Who shouldn’t use it: Not for women who are pregnant or may become pregnant. People with significant liver disease or certain other conditions should use it only if advised by a clinician.
- Pregnancy and contraception: Zytiga is not for use in pregnancy; men taking it should use effective contraception with partners who could become pregnant.
