Cautions
Caution in fluid retention, pulmonary infiltrates, CHF, lung disease, cardiac disease, hypoxia, hepatic/renal impairment; conditions may worsen
Solution should NOT be administered to neonates due to presence of benzyl alcohol in the formulation ant its association with "gasping syndrome"
Discontinue immediately if blast cells appear or disease progression occurs
Reformulated liquid devoid of sodium EDTA now available
Pregnancy and lactation
Pregnancy category: C
Lactation: Not known if excreted in breast milk
Pregnancy categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA: Information not available.
