Although no previous data on the use of eslicarbazepine acetate during lactation are available, limited but reassuring data have been reported with oxcarbazepine, of which eslicarbazepine is a major metabolite. Given the well-known benefits of breastfeeding, and according to the above reassuring data, breastfeeding under clinical supervision could be considered for healthy full-term infants of mothers on eslicarbazepine acetate monotherapy. However, parents should be warned that data concerning the safety of eslicarbazepine during breastfeeding are scarce, and long-term neurodevelopment outcomes in breastfed children are unknown. Additionally, the infants' serum levels should be measured in case of an unexplained adverse reaction.
