Warnings and precautions

Consult your doctor or pharmacist before starting treatment with this medicine:

Tell your doctor if you have been told you have any heart or blood vessel disorder, including heart rhythm problems (arrhythmia), or if you are being treated with medicines for these disorders.

Tell your doctor if you have yellowing of the skin or eyes, dark urine, or severe nausea or vomiting, as these may be signs or symptoms of liver problems. Rarely, liver failure (acute hepatic failure) may occur, which can be life-threatening.

A decrease in red blood cell count, reduced sexual desire, and cases of muscle weakness and/or muscle pain may occur.

Abiraterone should not be given in combination with Ra-223 due to a possible increased risk of bone fracture or death.

Other medicines and Abiraterone Zentiva

Consult your doctor or pharmacist before taking any medicine.

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This is important because abiraterone may increase the effects of certain medicines, including heart medicines, sedatives, some diabetes medicines, herbal medicines (e.g., St. John's Wort), and others. Your doctor may consider changing the dose of these medicines. Additionally, some medicines may increase or decrease the effects of abiraterone. This may lead to side effects or abiraterone may not work as well as it should. Androgen deprivation therapy may increase the risk of heart rhythm problems. Tell your doctor if you are being treated with:

• medicines used to treat heart rhythm problems (e.g., quinidine, procainamide, amiodarone, and sotalol);
• medicines that increase the risk of heart rhythm problems [e.g., methadone (used for pain relief and as part of drug addiction detoxification), moxifloxacin (an antibiotic), antipsychotics (used for severe mental illnesses)].

Consult your doctor if you are taking any of the medicines listed above.
