              Pregnancy & Lactation

              Pregnancy

              There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs); to enroll in the North American Antiepileptic Drug (NAAED) pregnancy registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/

              Available data from NAAED pregnancy registry, a prospective cohort study, case reports, and a case series in pregnant women are insufficient to identify a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes

              Lacosamide produced developmental toxicity (increased embryofetal and perinatal mortality, growth deficit) in rats following administration during pregnancy

              Developmental neurotoxicity was observed in rats following administration during a period of postnatal development corresponding to the third trimester of human pregnancy

              Lactation

              Data from published literature indicate that lacosamide is present in human milk; there are reports of increased sleepiness in breastfed infants exposed to lacosamide; there is no information on effects of lacosamide on milk production

              Studies in lactating rats have shown excretion of lacosamide and/or its metabolites in milk

              Developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for lacosamide and any potential adverse effects on the breastfed infant from lacosamide or from the underlying maternal condition

              Monitor infants exposed to drugs through breastmilk for excess sedation

              Pregnancy Categories

              A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

              B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

              C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

              D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

              X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

              NA: Information not available.
