1. what imatinib teva is and what it is used for

Imatinib Teva is a medicine containing an active substance called imatinib. This medicine works by inhibiting the growth of abnormal cells in the diseases listed below. These include some types of cancer.

Imatinib Teva is a treatment for adults and children for:

- Chronic myeloid leukaemia (CML). Leukaemia is a cancer of white blood cells. These white

cells usually help the body to fight infection. Chronic myeloid leukaemia is a form of leukaemia in which certain abnormal white cells (named myeloid cells) start growing out of control.

- Philadelphia chromosome positive acute lymphoblastic leukaemia (Ph-positive ALL). Leukaemia is a cancer of white blood cells. These white cells usually help the body to fight infection. Acute lymphoblastic leukaemia is a form of leukaemia in which certain abnormal white cells (named lymphoblasts) start growing out of control. Imatinib Teva inhibits the growth of these cells.

Imatinib Teva is also a treatment for adults for:

- Myelodysplastic/myeloproliferative diseases (MDS/MPD). These are a group of blood diseases in which some blood cells start growing out of control. Imatinib Teva inhibits the growth of these cells in a certain subtype of these diseases.
- Hypereosinophilic syndrome (HES) and/or chronic eosinophilic leukaemia (CEL). These are blood diseases in which some blood cells (named eosinophils) start growing out of control. Imatinib Teva inhibits the growth of these cells in a certain subtype of these diseases.
- Dermatofibrosarcoma protuberans (DFSP). DFSP is a cancer of the tissue beneath the skin in which some cells start growing out of control. Imatinib Teva inhibits the growth of these cells.

In the rest of this leaflet, we will use the abbreviations when talking about these diseases.

If you have any questions about how Imatinib Teva works or why this medicine has been prescribed for you, ask your doctor.

2. what you need to know before you take imatinib teva

Imatinib Teva will only be prescribed to you by a doctor with experience in medicines to treat blood cancers or solid tumours.

Follow all your doctor’s instructions carefully, even if they differ from the general information contained in this leaflet.

Do not take Imatinib Teva

– if you are allergic to imatinib or any of the other ingredients of this medicine (listed in section 6).

If this applies to you, tell your doctor without taking Imatinib Teva.

If you think you may be allergic but are not sure, ask your doctor for advice.

Warnings and precautions

Talk to your doctor before taking Imatinib Teva:

– if you have or have ever had a liver, kidney or heart problem.
– if you are taking the medicine levothyroxine because your thyroid has been removed.
– if you have ever had or might now have a hepatitis B infection. This is because Imatinib Teva

could cause hepatitis B to become active again, which can be fatal in some cases. Patients will be carefully checked by their doctor for signs of this infection before treatment is started.

– if you experience bruising, bleeding, fever, fatigue and confusion when taking Imatinib Teva, contact your doctor. This may be a sign of damage to blood vessels known as thrombotic microangiopathy (TMA).

If any of these apply to you, tell your doctor before taking Imatinib Teva

You may become more sensitive to the sun while taking Imatinib Teva. It is important to cover sun-exposed areas of skin and use sunscreen with high sun protection factor (SPF). These precautions are also applicable to children.

During treatment with Imatinib Teva, tell your doctor straight away if you put on weight very quickly. Imatinib Teva may cause your body to retain water (severe fluid retention).

While you are taking Imatinib Teva your doctor will regularly check whether the medicine is working. You will also have blood tests and be weighed regularly.

Children and adolescents

Imatinib Teva is also a treatment for children and adolescents with CML. There is no experience in children with CML below 2 years of age. There is limited experience in children with Ph-positive ALL and very limited experience in children with MDS/MPD, DFSP and HES/CEL.

Some children and adolescents taking Imatinib Teva may have slower than normal growth. The doctor will monitor the growth at regular visits.

Other medicines and Imatinib Teva

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription (such as paracetamol) and including herbal medicines (such as St. John’s Wort). Some medicines can interfere with the effect of Imatinib Teva when taken together. They may increase or decrease the effect of Imatinib Teva, either leading to increased side effects or making Imatinib Teva less effective. Imatinib Teva may do the same to some other medicines.

Tell your doctor if you are using medicines that prevent the formation of blood clots.

Pregnancy, breast-feeding and fertility

– If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
