•
Reconstitute 50 mg and 200 mg powder for injection vials with 25 ml and 100 ml, respectively, of Sterile Water for Injection (2 mg/ml), shake vigorously for up to 4 min; reconstituted sols are stable for 24 hr when stored refrigerated and protected from light or at room temperature in normal light
•
Solution can be further diluted with Sterile Water for Injection
•
Give doses of 100–120 mg/m

W IV inf over 15–20 min; the infusion time may be decreased, proportionally, in those who require lower doses; infusion times <3 min are not recommended
•
Direct injection into the vein is not recommended because of the risk of extravasation; avoid use with any solution of alkaline pH because hydrolysis will occur
•
Dilute dose in 0.9% sodium chloride (NS) or D
5
W, infuse over 30–60 min, avoid use with any solution of alkaline pH because hydrolysis will occur
