Administration of drug until permission of all by-effects can be postponed for 1_2 weeks. At development against the background of treatment of the expressed oppression of a marrowy hemopoiesis (quantity of neutrophils <500/mkl, and/or quantity of leukocytes <1000/mkl, and/or quantity of thrombocytes <100 000/mkl), a febrile neutropenia (quantity of neutrophils _1000/mkl blood in combination with fervescence more than 38 °C), infectious complications, heavy diarrhea or other not hematologic toxicity 3_4 degrees the subsequent doses of Irnokam and in need of a 5-ftoruratsil it is necessary to reduce by 15_20%.
At patients with abnormal liver functions at the bilirubin level in blood serum exceeding VGN no more than by 1.5 times in connection with the increased risk of development of the expressed neutropenia it is necessary to control carefully blood indicators at the patient. At increase in level of bilirubin more than by 1.5 times – treatment by Irnokam should be stopped.
At renal failures of Irnokam® it is not recommended to appoint since data on use of an irinotekan for this category of patients are absent. Any special application instructions of an irinotekan at patients of advanced age are absent. The drug dose in each case should be selected with care.
