With the development during treatment pronounced inhibition of bone marrow hematopoiesis (neutrophil count less than 500 / ml, and / or white blood cell count less than 1000 / mm, and / or platelet count of less than 100,000 / ul), febrile neutropenia (neutrophil count 1000 / ml of blood or less in combination with fever over 38 ° C), infectious complications, severe diarrhea, or other hematological toxicity grade 3-4 Kamptotekana subsequent doses, and if necessary 5 -ftoruratsila should be reduced by 15-20%. Patients with impaired liver function. When the bilirubin level in blood serum higher than the upper normal limit of no more than 1.5 times, due to the increased risk of severe neutropenia should be carefully monitored blood parameters of the patient . When the bilirubin level more than 1.5 times – Kamptotekanom treatment should be discontinued. Patients with impaired renal function.

From the side of hematopoiesis: neutropenia is observed on average 80% of patients, including half of them there is a decrease of neutrophils less than 1,000 cells in 1 mm. Recovery of neutrophils usually occurs 7-20 days after the start of treatment. Anemia varying severity occurs on average 60% ??of patients, and thrombocytopenia – 7% of patients. We describe a case of thrombocytopenia with the formation of anti-platelet antibodies. On the part of the digestive system: Late diarrhea occurring more than 24 hours (on average 5 days) after administration of the drug is a dose-limiting toxicities observed in approximately 87% of patients with severe – at 38%. Nausea and vomiting is usually occurs on the first day of administration or after 24 hours in 85% of patients.

The main expected manifestations of overdose – neutropenia and diarrhea.
The specific antidote for irinotecan unknown. Treatment is symptomatic. In the case of an overdose the patient should be hospitalized and carefully monitor the function of vital organs.
Interaction with other drugs
Since irinotecan has anticholinesterase activity may increase the duration of neuromuscular blockade when combined with suxamethonium and antagonize the interaction against neuromuscular blockade when combined with non-depolarizing muscle relaxants.
Kamptotekan should not be mixed with other medications in the same bottle.
Should be carried out in specialized chemotherapy wards under the supervision of a physician who has experience with anticancer drugs.
Patients receiving , you must make weekly detailed clinical analysis of blood and monitor liver function.
Diarrhea that arises as a consequence of the cytotoxic action of the drug, usually marked not earlier than 24 hours after administration Kamptotekana (the majority of patients after an average of 5 days).When the first episode of loose stools assignment must abundant drink containing electrolytes and the immediate holding antidiarrheal therapy comprising loperamide receiving high doses (4 mg and the first reception then 2 mg every 2 hours).
