100 mg film-coated tablets

What Imatinib Teva is and what it is used for

Imatinib Teva is a medicine that contains an active substance called imatinib. The drug acts by inhibiting the growth of abnormal cells in the diseases listed below. These include certain types of cancer.

Imatinib Teva is a treatment for adults and children for:

  • Chronic myeloid leukemia (CML) . Leukemia is a cancer of the white blood cells . These white blood cells usually help the body fight infection . Chronic myeloid leukemia is a form of leukemia in which certain abnormal white blood cells (so-called myeloid cells) begin to grow out of control.
  • Philadelphia chromosome-positive acute lymphoblastic leukemia ( Ph- positive ALL). Leukemia is a cancer of the white blood cells . These white blood cells normally help your body fight infection . Acute lymphoblastic leukemia is a form of leukemia in which certain abnormal, immature white blood cells (so-called lymphoblasts ) begin to grow out of control. Imatinib Teva inhibits the growth of these cells.

Imatinib Teva is also an adult treatment for:

  • Myelodysplastic / myeloproliferative disorders (MDS / MPD). These are a group of blood diseases in which certain blood cells begin to grow out of control. Imatinib Teva inhibits the growth of these cells in a certain subset of these diseases.
  • Hypereosinophilic syndrome (HES) and / or chronic eosinophilic leukemia (CEL). These are blood diseases in which certain blood cells (so-called eosinophils ) begin to grow out of control. Imatinib Teva inhibits the growth of these cells in a certain subset of these diseases.
  • Dermatofibrosarcoma protuberance (DFSP). DFSP is a cancer of the tissue under the skin in which certain cells begin to grow out of control. Imatinib Teva inhibits the growth of these cells.

In the rest of this leaflet, abbreviations will be used when talking about these diseases.

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