Ezogabine

Summary of Use during Lactation

Ezogabine is no longer marketed in the US. Because no information is available on use of ezogabine during breastfeeding, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. If ezogabine is required by the mother, it is not necessarily a reason to discontinue breastfeeding, but monitor the infant for drowsiness, agitation, adequate weight gain, and developmental milestones, especially in younger, exclusively breastfed infants and when using combinations of drugs.

Drug Levels

In published reports of anticonvulsant use during breastfeeding, most women were taking a combination of anticonvulsants. Some other anticonvulsants (e.g., phenytoin, carbamazepine) stimulate the metabolism of other drugs including anticonvulsants, whereas others (e.g., valproic acid) inhibit the metabolism of other drugs. Therefore, the relationship of the maternal dosage to the concentration in breastmilk can be quite variable, making calculation of the weight-adjusted percentage of maternal dosage less meaningful than for other drugs in this database.
