Cancer is the uncontrolled growth of abnormal cells anywhere in a body. The abnormal cells are termed cancer cells, malignant cells, or tumor cells. Many cancers and the abnormal cells that compose the cancer tissue are further identified by the name of the tissue that the abnormal cells originated from (for example, breast cancer, lung cancer, colon cancer). Cancer is not confined to humans; animals and other living organisms can get cancer. Below is a schematic that shows normal cell division and how when a cell is damaged or altered without repair to its system, the cell usually dies. Also shown is what can occur when such damaged or unrepaired cells do not die and become cancer cells and proliferate with uncontrolled growth; a mass of cancer cells develop. Frequently, cancer cells can break away from this original mass of cells, travel through the blood and lymph systems, and lodge in other organs where they can again repeat the ...
Ibritumomab is a protein that targets white blood cells in the body. When ibritumomab is attached to a radioactive chemical, the radiation is delivered directly to the tumor (lymphoma).
Ibritumomab is used in combination with other medicines to treat non-Hodgkin's lymphoma.
Ibritumomab may also be used for purposes other than those listed in this medication guide.
Some people receiving an ibritumomab injection have had a reaction to the infusion (when the medicine is injected into the vein). Tell your caregiver right away if you feel dizzy, nauseated, light-headed, sweaty, itchy, or have a fast heartbeat, trouble breathing, chest pain or heavy feeling, or pain spreading to the arm or shoulder. These reactions can occur during the injection or within 24 hours afterward.
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have any of these serious side effects:
Less serious side effects may include:
This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.
Do not receive this medication if you are pregnant. It could cause harm to the unborn baby. Use an effective form of birth control, and tell your doctor if you become pregnant during treatment.
Ibritumomab can lower the blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Contact your doctor immediately if you develop signs of infection.
Do not receive a "live" vaccine while you are being treated with ibritumomab, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you.
Some people receiving ibritumomab have developed "secondary" bone marrow or blood cell cancers such as leukemia. Talk with your doctor about your individual risk while receiving this medication.
