Abiraterone 250mg: Uses, Dosage, Side Effects and Safety Information

Abiraterone is an oral hormone therapy for advanced prostate cancer, notable for a strict food-timing rule that patients need to follow carefully. Here is what this Abiraterone prostate cancer guide outlines for patients and caregivers.

What Is It?

Abiraterone acetate blocks an enzyme (CYP17) needed to produce testosterone and other androgens, not just in the testes but throughout the body, including within tumour tissue, making it effective even after other hormone therapies stop working.

How Does It Work?

By inhibiting CYP17, abiraterone starves prostate cancer cells of the androgen signal they depend on to grow, and is always given together with a steroid (prednisone or prednisolone) to prevent hormonal side effects.

Who Is It Prescribed For?

• Adults with metastatic castration-resistant or high-risk hormone-sensitive prostate cancer, prescribed by an oncologist or urologist.

Dosage and How to Take It

The standard adult dose is 1,000mg daily, typically four 250mg tablets taken together once daily. This medicine must be taken on a strictly empty stomach, at least one hour before or two hours after a meal, food can increase absorption several-fold and raise the risk of side effects. Always take alongside the prescribed steroid dose.

What If I Miss a Dose?

If a dose is missed, skip it and resume the normal schedule the next day; do not double up.

Common Side Effects

• Fluid retention or swelling in the legs

• High blood pressure

• Fatigue

• Hot flashes

• Low potassium levels (monitored by blood tests)

Serious Side Effects, Seek Help If You Notice:

• Signs of liver problems: yellowing skin or eyes, dark urine, severe fatigue

• Signs of adrenal problems if steroid doses are missed: severe weakness, dizziness, low blood pressure

• Irregular heartbeat or chest pain

• Signs of infection alongside steroid use

Warnings and Precautions

As emphasized in this Abiraterone prostate cancer guide, liver function must be checked before starting and monitored regularly during treatment. The steroid taken alongside abiraterone should never be stopped abruptly without medical guidance. Blood pressure and potassium levels are monitored throughout treatment.

Drug and Food Interactions

Taking this medicine with food significantly increases drug absorption and side-effect risk, the empty-stomach rule is not optional. It also interacts with several other medicines processed by the liver; share your full medicine list with your pharmacist.

Storage

Store below 30°C in the original container, away from direct sunlight and moisture. Women who are pregnant or may become pregnant should avoid handling broken or crushed tablets.

Frequently Asked Questions

Why is the empty-stomach rule so strict? Taking abiraterone with food can increase the amount absorbed into the blood by several times, which raises the risk of side effects without added benefit.

Can I stop taking the steroid on my own if I feel better? No, stopping the steroid abruptly can cause a dangerous drop in cortisol; any change must be directed by your oncology team.
