Imatinib Richter 400 mg filmomhulde tabletten

Imatinib Richter 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 Richter is a treatment for adults and children with 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.

In adult patients Imatinib Richter is used to treat a late stage of Chronic Myeloid Leukaemia called “blast crisis.” In children and adolescents however it may be used to treat all stages of the illness.

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

Imatinib Richter will only be prescribed to you by a doctor with experience in medicines to treat blood cancers.

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

Do not take Imatinib Richter:

- 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 Richter.

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 Richter:

• 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 any of these apply to you, tell your doctor before taking Imatinib Richter.

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

Imatinib Richter is also a treatment for children with CML. There is no experience in children with CML below 2 years of age.

(such as St. John’s Wort). Some medicines can interfere with the effect of Imatinib Richter when taken together. They may increase or decrease the effect of Imatinib Richter, either leading to increased side effects or making Imatinib Richter less effective. Imatinib Richter may do the same to some other medicines.
