Abiraterone Dosage & 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: previous heart attack, high blood pressure, liver problems.

Abiraterone may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using abiraterone, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using abiraterone safely.

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).

Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).

This medication should not be used in women, especially during pregnancy or breast-feeding. It may harm an unborn or breast-feeding baby. Women who are pregnant or breast-feeding should avoid touching or accidentally taking this medication. Consult your doctor for more details.

Because it is unknown if abiraterone passes into semen, men who use this drug and have sex with pregnant women must use a latex condom during all sexual contact, even if they have had a vasectomy. Men who use this drug and have sex with women of child-bearing age should use a latex condom and another reliable form of birth control (such as diaphragm with spermicide) during all sexual contact. Continue using reliable form(s) of birth control as directed until 3 weeks after abiraterone treatment has been stopped.

If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center.

Missed Dose

If you miss a dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up. If you miss more than one dose, talk to your doctor right away.
