Breastfeeding: Likely unsafe; if bupropion is used during lactation, monitor infants for adverse events including development of seizures, serum levels to rule out toxicity should be monitored. Other drugs may be preferred, especially if breastfeeding a newborn or a preterm infant. This information is based upon LactMed database (available at http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?LACT last accessed 01 August 2013).
