Prostate cancer is one of the most common cancers in men. When it spreads or stops responding to standard hormone treatments, doctors often turn to medicines like abiraterone. This drug has helped many men live longer and feel better. In this guide, we’ll explain what abiraterone is, how it works, who it helps, how to take it, possible side effects, and more. The goal is to give you clear facts so you can talk better with your doctor.
What Is Abiraterone?
Abiraterone, often sold as Zytiga, is a pill used to treat advanced prostate cancer. It’s a type of hormone therapy. Prostate cancer cells usually need male hormones called androgens—like testosterone—to grow. Abiraterone stops the body from making these hormones in new ways.
Unlike some treatments that only lower testosterone from the testicles, abiraterone blocks production from other places too, like the adrenal glands and even inside the cancer cells themselves. This makes it stronger against cancer that keeps growing despite other hormone blockers.

How Does Abiraterone Work?
Prostate cancer grows when androgens attach to receptors on cancer cells. Standard treatments like surgery or shots reduce testosterone from the testicles. But the body has backup paths to make small amounts of androgens elsewhere.
Abiraterone targets an enzyme called CYP17. This enzyme helps turn other substances into androgens. By blocking CYP17, abiraterone cuts off almost all androgen supply. This starves the cancer cells, slowing growth or shrinking tumors.
Doctors give it with a low-dose steroid like prednisone. This helps prevent side effects from low hormones.

Who Can Benefit from Abiraterone?
Doctors prescribe abiraterone for men with prostate cancer that has spread (metastatic) in two main cases:
- Metastatic castration-resistant prostate cancer (mCRPC): The cancer no longer responds to treatments that lower testosterone, and it has spread.
- Metastatic high-risk castration-sensitive prostate cancer: The cancer still responds to hormone lowering, but it’s aggressive and has spread.
Studies show it can extend life, delay pain or bone problems, and improve quality of life. It’s often used after or with other treatments.
How to Take Abiraterone
The standard dose is 1000 mg once a day—usually two 500 mg tablets or four 250 mg ones. Take it on an empty stomach: at least one hour before food or two hours after. Swallow whole with water.
You also take prednisone: 5 mg twice a day for castration-resistant cases, or once a day for castration-sensitive. Follow your doctor’s exact plan.
Some newer options use lower doses with food, but stick to what your doctor says. Regular blood tests check liver function, blood pressure, and potassium levels.
Common Side Effects and How to Manage Them
Like most cancer drugs, abiraterone can cause side effects. Many are mild and can be handled.
Common ones include:
- Tiredness or weakness
- High blood pressure
- Swelling in legs or feet from fluid buildup
- Low potassium levels
- Hot flashes
- Joint pain
- Liver changes (shown in blood tests)
Less common but serious: heart issues, low blood sugar, or bone thinning from long-term steroid use.
To help:
- Check blood pressure often.
- Eat potassium-rich foods like bananas (if your doctor okays it).
- Report swelling, shortness of breath, or chest pain right away.
- Stay active if you can, and talk about bone health.
Most men tolerate it well with monitoring.
Monitoring and Follow-Up
While on abiraterone, you’ll see your doctor regularly. They check PSA levels, scans, and blood work. This helps see if it’s working and catch side effects early.
If side effects get bad, your doctor might pause treatment or adjust doses. Never stop on your own.
Key Takeaways
- Abiraterone is a powerful hormone therapy that blocks androgen production more completely.
- It helps men with advanced prostate cancer live longer and with fewer symptoms.
- Take it correctly—on an empty stomach—with prednisone.
- Side effects are common but often manageable with doctor help.
- Always work closely with your oncology team.
This treatment is part of modern prostate cancer care. Many men find it makes a real difference.
