Serum Bupropion Levels in 2 Breastfeeding Mother-Infant Pairs.
Background: These are the first reported data on bupropion and hydroxybupropion levels in infants whose treated mothers were breastfeeding. The information will assist physicians and parents in the risk-benefit decision-making process for bupropion treatment during breastfeeding.
Method: Serum samples were obtained by venipuncture from 2 mother-infant pairs. The serum was assayed for levels of bupropion and its most active metabolite, hydroxybupropion.
Results: Neither infant had quantifiable serum levels of bupropion or its metabolite at steady state. Neither infant had medical problems during the time of maternal therapy.
Conclusion: We recommend obtaining and publishing additional serum level findings for breastfeeding mother-infant pairs since data for bupropion are favorable but limited.
