• Hemorrhagic pancreatitis
• Hepatotoxicity
• Coagulation defects
• Hyperglycemia (secondary to altered insulin synthesis)

주의사항 및 금기

• Patients with a history of anaphylaxis to asparaginase
• Patients with pancreatitis or a history of pancreatitis
• Use with caution in patients with preexisting hepatic, renal, hematologic, gastrointestinal, or CNS dysfunction. Intravenous (IV) administration is generally avoided as it significantly increases the risk of anaphylaxis. Premedication with an antihistamine (e.g., diphenhydramine) is strongly recommended. Asparaginase can be a contact irritant; wash off any inadvertent skin contact. May alter thyroid function tests by decreasing thyroxine-binding globulin (TBG).

약물 상호작용

• Methotrexate: Asparaginase may reduce methotrexate effectiveness against tumor cells until serum asparagine levels return to normal.
• Prednisone: Concurrent use may increase the risk for hyperglycemia.
• Vincristine: Increased toxicity (neuropathy and erythropoiesis disruption) and myelosuppression may occur. Some oncologists recommend separating the dosing by a few days to a week.
