US BOXED WARNINGS:
- This drug should be administered under the supervision of a physician experienced in the use of antineoplastic therapy.
- This drug can severely suppress bone marrow function.
- When used at high doses in dose-ranging studies in patients with acute leukemia it was associated with severe neurologic effects, including blindness, coma, and death. This severe central nervous system toxicity occurred in 36% of patients treated with doses approximately 4 times greater (96 mg/m2/day for 5 to 7 days) than the recommended dose. Similar severe central nervous system toxicity, including coma, seizures, agitation, and confusion has been reported in patients treated at doses in the range of the dose recommended for chronic lymphocytic leukemia.
- Instances of life-threatening and sometimes fatal autoimmune phenomena (e.g., hemolytic anemia, autoimmune thrombocytopenia/thrombocytopenic purpura (ITP), Evan's syndrome, acquired hemophilia) have been reported after one or more cycles of therapy. Patients should be monitored for hemolysis.
