1. What is and what it is used for

Imatinib belongs to a group of medicines known as protein kinase inhibitors. This medicine works by inhibiting the growth of abnormal cells in the diseases listed below. These include some types of cancer.

Imatinib is a treatment for adults and children for:

Chronic myeloid leukaemia (CML). In adults it is used to treat a certain subtype of this disease called “blast crisis”. In children and adolescents, however, it may be used to treat all stages of the illness. 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.

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

Warnings and precautions

Other medicines and <Imatinib>

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 when taken together. They may increase or decrease the effect of imatinib, either leading to increased side effects or making imatinib less effective. Imatinib may do the same to some other medicines.
