Limited data indicate that this drug is found in breastmilk for 2 days and its active metabolite is found in breastmilk for up to a week after a dose of 60 mg/m2, although the highest amounts occur during the first 4 days after a dose. Breastfeeding should be avoided for at least a week after a dose. Higher dosages probably require a longer abstinence period. Some experts consider breastfeeding to be contraindicated during therapy.
