Other Comments

It is recommended that patients receive hydration with 500 to 1,000 mL of 5% dextrose in 0.5 normal saline or equivalent before pentostatin administration. An additional 500 mL of 5% dextrose or equivalent should be administered after pentostatin is given.

The optimal duration of treatment has not been determined. In the absence of major toxicity and with observed continuing improvement, the patient should be treated until a complete response has been achieved. Although not a requirement, the administration of two additional doses has been recommended following the achievement of a complete response.
