Drug Levels and Effects
Summary of Use during Lactation
No information is available on the use of bendamustine during breastfeeding. Most sources consider breastfeeding to be contraindicated during maternal antineoplastic drug therapy, especially alkylating agents such as bendamustine.[1] The manufacturer recommends that breastfeeding be discontinued during bendamustine therapy. Based on the half-life of the drug and its metabolites, the drug should be eliminated from the milk by 24-48 hours after the last dose.
