1. What TRISENOX is and what it is used for
TRISENOX is used in adult patients with newly diagnosed low-to-intermediate risk acute promyelocytic leukaemia (APL), and in adult patients, whose disease has not responded to other therapies. APL is a unique type of myeloid leukaemia, a disease in which abnormal white blood cells and abnormal bleeding and bruising occur.
2. What you need to know before you are given TRISENOX
TRISENOX must be given under the supervision of a physician experienced in the treatment of acute leukaemias.

Warnings and precautions
You must talk to your doctor or nurse before you are given TRISENOX, if

Your doctor will take the following precautions:
- Tests will be performed to check the amount of potassium, magnesium, calcium and creatinine in your blood before your first dose of TRISENOX
- You should have an electrical recording of the heart (electrocardiogram ECG) performed before your first dose
- Blood tests (potassium, calcium, magnesium and liver function) should be repeated during your treatment with TRISENOX
- In addition, you will receive electrocardiograms twice weekly
- If you are at risk for a certain type of abnormal heart rhythm (e.g. torsade de pointes or QTc prolongation), your heart will be monitored continuously
- Your doctor may monitor your health during and after treatment, since arsenic trioxide, the active substance in TRISENOX, may cause other cancers. You should report any new and exceptional symptoms and circumstances whenever you see your doctor

Other medicines and TRISENOX
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.
In particular tell your doctor
if you are taking any of various types of medicines which could cause a change in the rhythm of your heartbeat. These include:
° some types of antiarrhythmics (medicines used to correct irregular heart beats, e.g. quinidine, amiodarone, sotalol, dofetilide)
° medicines to treat psychosis (loss of contact with reality, e.g. thioridazine)
° medicines for depression (e.g. amitriptyline) ° some types of medicines to treat bacterial infections (e.g. erythromycin and sparfloxacin)
° some medicines to treat allergies such as hay fever, called antihistamines (e.g. terfenadine and astemizole) ° any medicines that cause a decrease in magnesium or potassium in your blood (e.g. amphotericin B) ° cisapride (a medicine used to relieve certain stomach problems).
The effect of these medicines on your heartbeat can be made worse by TRISENOX. You must be sure to tell your doctor about all medicines you are taking.
- if you are taking or have recently taken any medicine which may affect your liver. If you are not sure, show the bottle or pack to your doctor.
TRISENOX with food and drink

Pregnancy
Ask your doctor or pharmacist for advice before taking any medicine.
TRISENOX may cause harm to the foetus when used by pregnant women.

If you experience discomfort or if you feel unwell after a TRISENOX injection, you should wait until the symptoms go away before driving or using machines.
