There are no adequate and well-controlled studies of lamotrigine in pregnant women. Women who are pregnant while receiving lamotrigine should be encouraged to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry at 888-233-2334 or http://www.aedpregnancyregistry.org/.

Data from several prospective pregnancy exposure registries and epidemiological studies of pregnant women have not detected an increased frequency of major congenital malformations or a consistent pattern of malformations among women exposed to lamotrigine compared with the general population. The majority of lamotrigine pregnancy exposure data are from women with epilepsy. In animal reproduction studies, lamotrigine produced developmental toxicity (e.g., increased mortality, decreased body weight, increased structural variation, neurobehavioral abnormalities) when administered to pregnant animals at doses lower than those used clinically.

Lamotrigine decreased fetal folate concentrations in rats, an effect known to be associated with adverse pregnancy outcomes in animals and humans. Although preliminary information from the NAAED Pregnancy Registry suggested a possible association between exposure to lamotrigine monotherapy during the first trimester of pregnancy and an increased incidence of cleft lip or cleft palate in infants, this finding has not be observed in other international registries. The effect of lamotrigine on labor and delivery in humans is unknown.

Physiologic changes during pregnancy may affect plasma lamotrigine concentrations and/or therapeutic effect. Decreased lamotrigine concentrations during pregnancy and restoration of prepartum concentrations after delivery have been reported. Dosage adjustment of lamotrigine may be necessary to maintain clinical response.

Lamotrigine is distributed into human milk. There is some evidence that lamotrigine plasma concentrations in breast-fed infants may be as high as 50% of maternal serum levels. Exposure to lamotrigine in these infants may be further increased due to the immaturity of the infant glucuronidation process required for drug clearance.

Apnea, drowsiness, and poor sucking have been reported in nursing infants whose mothers were receiving lamotrigine, although it is not known whether these effects were caused by lamotrigine. It is not known whether lamotrigine can affect milk production. The known benefits of breast-feeding should be considered along with the mother's clinical need for lamotrigine and any potential adverse effects on the breast-fed infant from the drug or underlying condition.
