Do not use with concurrent fludarabine because of increased risk of pulmonary toxicity
Contraindications
Hypersensitivity
Concomitant fludarabine: risk of fatal pulmonary toxicity
Relative: active infections

Epilepsy, liver dz, bone marrow depression
Weigh risk/benefit for pts w/ infections
Withhold if elevated SCr, renal dysfunction
Withhold or discontinue if evidence of CNS toxicity
Avoid pregnancy
Pregnancy and lactation

Lactation: not known if excreted in breast milk, do not nurse
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.
