Zytiga Side Effects: What to Expect and How to Manage Them

Zytiga (abiraterone acetate) is a prescription medication used in the treatment of advanced prostate cancer in adults. It’s typically prescribed alongside prednisone to improve outcomes and manage potential side effects. While Zytiga is effective at slowing the growth of prostate cancer, like all medications, it comes with the risk of side effects — some mild, some more serious.

In this comprehensive guide, we’ll break down the common, mild, and serious side effects of Zytiga, explain how to manage them, and offer guidance on when to seek medical help.

These side effects may last for a few days to several weeks and often improve over time. However, if any of these symptoms persist or worsen, you should speak with your doctor.

Long-Term Side Effects and Management

Can Zytiga Cause Lasting Side Effects?

Yes. While some side effects resolve after treatment ends, others can lead to long-term complications, particularly:

• Liver problems
• High blood pressure
• Chronic low potassium
• Adrenal hormone imbalances

Doctors usually prescribe prednisone alongside Zytiga to reduce the risk of hormonal and adrenal complications. Regular blood tests and check-ups are essential for monitoring long-term safety.

How Long Do Side Effects Last?

The duration of side effects varies. Some, like nausea or hot flashes, may only last a few days or weeks. Others — particularly liver, blood pressure, or electrolyte issues — may continue throughout treatment and need ongoing management.

Consistent communication with your healthcare provider is key. They can adjust your dosage or provide medications to ease discomfort as needed.

Precautions Before Taking Zytiga

Before starting Zytiga, it’s important to share your full medical history with your doctor. Certain conditions can raise your risk of complications.

Inform Your Doctor If You Have:

• Heart conditions: Especially recent heart attack or irregular heartbeat
• High blood pressure
• Diabetes or blood sugar issues
• Liver disease or abnormal liver function
• Low potassium levels
• History of adrenal gland disorders
• Kidney problems
• Pituitary disorders
• Past allergic reactions to medications

Your doctor may monitor you more closely or adjust your treatment plan based on these factors.

Zytiga and Alcohol Use

While there’s no direct contraindication, both Zytiga and alcohol can affect the liver. Drinking alcohol during treatment may increase your risk of liver damage, especially if you already have liver concerns. If you consume alcohol, ask your doctor whether it’s safe to do so while on Zytiga.

---

Zytiga and Pregnancy

Zytiga is intended only for use in men with prostate cancer. However, it can be harmful to an unborn child if a woman is exposed during pregnancy. If you are a male with a partner who can become pregnant, use effective contraception during treatment and for at least 3 weeks after your last dose.
