abiraterone

COMMON BRAND NAME(S): Zytiga

GENERIC NAME(S): ABIRATERONE ACETATE

Uses

This medication is used along with prednisone to treat men with prostate cancer that has spread to other areas of the body and has not responded to other medical/surgical treatment that lowers testosterone levels. Abiraterone belongs to a class of drugs known as anti-androgens (anti-testosterone). Testosterone, a natural hormone, helps prostate cancer to grow and spread. Abiraterone works by blocking the production of testosterone, thereby slowing the growth and spread of prostate cancer.

This medication should not be given to women or children.

How to use abiraterone

Read the Patient Information Leaflet if available from your pharmacist before you start taking abiraterone and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth on an empty stomach, as directed by your doctor, usually once daily. Do not eat for at least 2 hours before and 1 hour after taking abiraterone. Taking abiraterone with food greatly increases the amount of this drug in your body and increases the risk of side effects.

Swallow whole. Do not crush or chew before swallowing. Pregnant women should wear gloves if handling the tablets. If the tablet is crushed or broken, women who are pregnant or who may become pregnant should not handle it or breathe the dust from it (see also Precautions section).

The dosage is based on your medical condition, lab results, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Do not stop any medications for your prostate cancer unless told to do so by your doctor. Stopping your medications could allow the cancer to spread more rapidly.

Tell your doctor if your condition persists or worsens (such as urination becomes more difficult, bone pain increases).

Side Effects

Headache, hot flushes, joint pain, heartburn or cold-like symptoms may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: increased urination, painful urination, fast/irregular heartbeat, muscle weakness, leg pain, swelling in legs/feet, bone fractures.

Get medical help right away if you have any very serious side effects, including: chest pain, feeling short of breath while at rest, yellowing eyes/skin, dark urine, severe abdominal/stomach pain.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Precautions

Before taking abiraterone, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: heart problems (such as heart failure, irregular heartbeat, previous heart attack), high blood pressure, liver problems.

Using corticosteroid medications for a long time along with abiraterone can make it more difficult for your body to respond to physical stress. Therefore, before having surgery or emergency treatment, or if you get a serious illness/injury, tell your doctor or dentist that you are using this medication or have used this medication within the past 12 months. Tell your doctor right away if you develop unusual/extreme tiredness or weight loss. If you will be using this medication for a long time, carry a warning card or medical ID bracelet that identifies your use of this medication.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

This medication is not usually used in women. Therefore, it is unlikely to be used during pregnancy or breast-feeding. Women who are pregnant or breast-feeding should avoid touching or accidentally taking this medication. Abiraterone may harm an unborn or nursing baby.

Because it is unknown if abiraterone passes into semen, men who use this drug and have sex with women must use a latex condom during all sexual contact, even if they have had a vasectomy. Continue using condoms as directed until 1 week after abiraterone treatment has been stopped.

Interactions

Other medications can affect the removal of abiraterone from your body, which may affect how abiraterone works. Examples include rifamycins (such as rifabutin), drugs used to treat seizures (such as carbamazepine, phenytoin, phenobarbital), among others.
