1. What is Abiraterona Stada and what is it used for

Abiraterona Stada contains the active substance abiraterone acetate. It is used for the treatment of prostate cancer in adult men that has spread to other parts of the body. Abiraterone makes your body stop producing testosterone; this can slow down the growth of prostate cancer.

When abiraterone is prescribed in the early stages of the disease and there is still a response to hormonal treatment, it is used together with a treatment to reduce testosterone (androgen deprivation therapy).

When you take this medicine, your doctor will also prescribe another medicine called prednisone or prednisolone to reduce the risk of high blood pressure, fluid retention, or low potassium levels in your blood.

2. What you need to know before you take Abiraterona Stada

• if you are a woman, especially if you are pregnant. Abiraterone should only be used in male patients.

varones.

Warnings and precautions

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

• if you have liver problems
• if you have been told you have high blood pressure or heart failure or low potassium levels in your blood (low potassium levels in your blood can increase the risk of heart rhythm problems)
• if you have had other heart or blood vessel problems
• if you have a fast or irregular heart rhythm
• if you have difficulty breathing
• if you have gained weight quickly
• if you have swelling in your feet, ankles, or legs
• if you have taken a medicine called ketoconazole in the past for prostate cancer
• about the need to take this medicine with prednisone or prednisolone
• about possible side effects on your bones
• if you have high blood sugar levels.

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 (called acute hepatic failure) may occur, which can be life-threatening.

A decrease in the number of red blood cells, 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 fractures or death.

If you plan to take Ra-223 after treatment with abiraterone and prednisone/prednisolone, you should wait 5 days before starting treatment with Ra-223.

If you are unsure if any of the above applies to you, consult your doctor or pharmacist before taking this medicine.

Blood tests

Abiraterone may affect your liver even if you do not have any symptoms. While you are taking this medicine, your doctor will perform regular blood tests to check for any effects on your liver.

Children and adolescents

This medicine should not be used in children or adolescents. If a child or adolescent accidentally ingests abiraterone, they should go to the hospital immediately and bring this leaflet with them to show to the emergency doctor.

Other medicines and Abiraterona Stada

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 can increase the effects of certain medicines, including heart medicines, tranquilizers, 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, which can lead to side effects or reduced effectiveness.

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); or 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.
