Is Carmustine safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Carmustine. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
No information is available on the use of carmustine during breastfeeding. Most sources consider breastfeeding to be contraindicated during maternal antineoplastic drug therapy, especially alkylating agents such as carmustine.[1] The manufacturer recommends that breastfeeding be discontinued during carmustine therapy and for 1 month after the last dose.
