Premedicate for nausea & vomiting. Rotate SC inj sites. Initially 75mg/m2 SC (doses >4mL divide equally into 2 syringes and inject into 2 separate sites, must administer within 1hr of reconstitution) or IV (infuse over 10–40mins, must complete within 1hr of reconstitution) daily for 7 days; repeat cycle every 4 weeks. May increase to 100mg/m2 after 2 cycles if no response and no toxicity. Treat for at least 4–6 cycles. Adjust subsequent doses based on nadir counts, hematologic response, serum electrolytes, and renal toxicity; see full labeling.
Children Dosage:
MDS: not established. JMML: <1mo: not established. Premedicate for nausea & vomiting. Give as IV infusion (infuse over 10–40mins, must complete within 1hr of reconstitution) for 7 days in a 28-day cycle. 1mo–<1yr (or <10kg): 2.5mg/kg; ≥1yr (and ≥10kg): 75mg/m2. Treat for at least 3 cycles and max of 6 cycles. May consider a delay in dose not exceeding 14 days for non-hematologic toxicities. Monitor for hematologic response, serum electrolytes, and renal toxicity; adjust dose if necessary. If hematological toxicity within the first 3 cycles: dose reductions are not recommended. Discontinue therapy if neutrophil count <0.5x109/L at the end of cycle 3 or on day 1 of cycles 5 or 6.
