Limited information indicates that maternal bupropion doses of up to 300 mg daily produce low levels in breastmilk and would not be expected to cause any adverse effects in breastfed infants. However, there is little reported use in breastfed newborn infants and case reports of a possible seizure in partially breastfed 6-month-olds. A safety scoring system finds bupropion use to be possible with caution during breastfeeding and some guidelines recommend that it can be used in smoking cessation.[1,2] If bupropion is required by a nursing mother, it is not a reason to discontinue breastfeeding. However, another drug may be preferred, especially while nursing a newborn or preterm infant. Infants exposed to bupropion and an SSRI through breastfeeding should be closely monitored for vomiting, diarrhea, jitteriness, or sedation and possibly measurement of serum levels to rule out toxicity if there is a concern.
