-This drug should be administered under the supervision of a qualified physician experienced in the use of antineoplastic therapy.
-Suppression of bone marrow function should be anticipated. This is usually reversible and appears to be dose dependent.
-Serious neurological toxicity (including irreversible paraparesis and quadriparesis) has been reported in patients who received this drug by continuous infusion at high doses (4 to 9 times the recommended dose for Hairy Cell Leukemia). Neurologic toxicity appears to demonstrate a dose relationship; however, severe neurological toxicity has been reported rarely following treatment with standard dosing regimens.
-Acute nephrotoxicity has been observed with high doses of this drug (4 to 9 times the recommended dose for hairy cell leukemia), especially when given concomitantly with other nephrotoxic agents/therapies.

Safety and efficacy have not been established in patients younger than 18 years.

Other Comments

-Careful monitoring of body temperature, complete blood cell counts, serum electrolytes, BUN, and creatinine concentrations is recommended for at least 4 to 8 weeks.
-Profound bone marrow suppression should be expected within the first 2 weeks of therapy. Red blood cell transfusions and platelet transfusions may be necessary.
-Consideration should be given to delaying or discontinuing therapy if neurotoxicity or renal toxicity occurs.
-The risk of opportunistic infection is significant, particularly in cases of febrile neutropenia.
