1. what deferasirox is and what it is used fordeferasirox contains an active substance called deferasirox. it is an iron chelator which is a medicine used to remove the excess iron from the body (also called iron overload). it traps and removes excess iron which is then excreted mainly in the stools.

What Deferasirox is used for

Repeated blood transfusions may be necessary in patients with various types of anaemia (for example thalassaemia, sickle cell disease or myelodysplastic syndromes (MDS)). However, repeated blood transfusions can cause a build-up of excess iron. This is because blood contains iron and your body does not have a natural way to remove the excess iron you get with your blood transfusions. In patients with non-transfusion-dependent thalassaemia syndromes, iron overload may also develop over time, mainly due to increased absorption of dietary iron in response to low blood cell counts. Over time, the excess iron can damage important organs such as the liver and heart. Medicines called iron chelators are used to remove the excess iron and reduce the risk of it causing organ damage.

Deferasirox is used to treat chronic iron overload caused by frequent blood transfusions in patients with beta thalassaemia major aged 6 years and older.

Deferasirox is also used to treat chronic iron overload when deferoxamine therapy is contraindicated or inadequate in patients with beta thalassaemia major with iron overload caused by infrequent blood transfusions, in patients with other types of anaemias, and in children aged 2 to 5 years.

Deferasirox is also used when deferoxamine therapy is contraindicated or inadequate to treat patients aged 10 years or older who have iron overload associated with their thalassaemia syndromes, but who are not transfusion dependent.

2. what you need to know before you take deferasirox are allergic to deferasirox or any of the other ingredients of this medicine (listed in section 6). if this applies to you, tell your doctor before taking deferasirox. if you think you may be allergic, ask your doctor for advice.

• have moderate or severe kidney disease
• are currently taking any other iron chelator medicines.

Deferasirox is not recommended if you:

• are at an advanced stage of myelodysplastic syndrome (MDS; decreased production of blood cells by the bone marrow) or have advanced cancer.

Warnings and precautions

Talk to your doctor or pharmacist before taking Deferasirox if you:

• have a kidney or liver problem
• have a cardiac problem due to iron overload
• notice a marked decrease in your urine output (sign of kidney problem)
• develop a severe rash, or difficulty breathing and dizziness or swelling mainly of the face and

throat (signs of severe allergic reaction, see also section 4 “Possible side effects”)

• experience a combination of any of the following symptoms: rash, red skin, blistering of the lips, eyes or mouth, skin peeling, high fever, flu-like symptoms, enlarged lymph nodes (signs of severe skin reaction, see also section 4 “Possible side effects”)
• experience a combination of drowsiness, upper right abdominal pain, yellowing or increased yellowing of your skin or eyes and dark urine (signs of liver problems)
• experience difficulty thinking, remembering information, or solving problems, being less alert or aware or feeling very sleepy with low energy (signs of a high level of ammonia in your blood, which may be associated with liver or renal problems, see also section 4 “Possible side effects”)
• vomit blood and/or have black stools
• experience frequent abdominal pain, particularly after eating or taking Deferasirox
• experience frequent heartburn
• have a low level of platelets or white blood cells in your blood test
• have blurred vision
• have diarrhoea or vomiting.

If any of these apply to you, tell your doctor straight away.

Monitoring your Deferasirox treatment

You will have regular blood and urine tests during treatment. These will monitor the amount of iron in your body (blood level of ferritin) to see how well Deferasirox is working. The tests will also monitor your kidney function (blood level of creatinine, presence of protein in the urine) and liver function (blood level of transaminases). Your doctor may require you to undergo a kidney biopsy, if he/she suspects significant kidney damage. You may also have MRI (magnetic resonance imaging) tests to determine the amount of iron in your liver. Your doctor will take these tests into consideration when deciding on the dose of Deferasirox most suitable for you and will also use these tests to decide when you should stop taking Deferasirox.

Your eyesight and hearing will be tested each year during treatment as a precautionary measure.

Other medicines and Deferasirox

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes in particular:

• simvastatin (used to lower cholesterol)
• certain painkillers or anti-inflammatory medicines (e.g. aspirin, ibuprofen, corticosteroids)

• anticoagulant medicines (used to prevent or treat blood clotting)
• hormonal contraceptive agents (birth control medicines)
• bepridil, ergotamine (used for heart problems and migraines)
