1. In women with epilepsy of childbearing age, preemptive administration of folic acid prior to pregnancy does reduce the incidence of congenital developmental malformations in the fetus, and therefore it is recommended that all women of childbearing potential, regardless of epilepsy, should be encouraged to take at least 0.4 mg of folic acid daily before and during pregnancy. There is insufficient evidence that newborns born to women with epilepsy taking antiepileptic drugs are more likely to have intracranial hemorrhage complications than the general population; there is also a lack of evidence that pre-supplementation with Vit K reduces the risk of intracranial hemorrhage in newborns. However, routine Vit K supplementation should be recommended for neonates exposed to maternal enzyme inducers to avoid intracranial hemorrhage. Lupina, paroxetine, phenytoin sodium, carbamazepine, levetiracetam, and valproic acid are likely to cross the placenta and may affect the fetus, and gabapentin, paroxetine, lamotrigine, and topiramate are more likely to leak into breast milk and therefore may affect lactation. However, there is no definite conclusion on what AEDs are easily absorbed by the newborn through maternal milk and the possible effects after absorption. 4. It is recommended that patients taking lamotrigine, carbamazepine, and phenytoin sodium should have their blood concentrations monitored during pregnancy, and for those taking levetiracetam and oxcarbazepine, it is recommended that drug concentration monitoring be performed. In particular, patients taking lamotrigine should pay attention to adjusting the drug dose to maintain a stable level close to the pre-pregnancy level so that patients can obtain better seizure control during pregnancy due to the possibility of large blood concentration fluctuations and increased seizure frequency. In particular, valproic acid is definitely not recommended for use during pregnancy because it causes anatomical and behavioral defects in the embryo, and it is believed that whether any of the antiepileptic drugs cause MCM (congenital developmental malformations) in the fetus is related to the dose of AEDs.
