Drug Levels and Effects

Summary of Use during Lactation

There is no published experience with atomoxetine during breastfeeding, although reports from the manufacturer found no serious adverse effects in two breastfed infants. If the mother of an older infant requires atomoxetine, it is not a reason to discontinue breastfeeding, but until more data become available, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. Monitor breastfed infants for excess sedation.
