Pregnancy and epilepsy: pharmacokinetic insights into antiseizure medications

Therapeutic drug monitoring is a valuable tool for tailoring antiseizure treatment in women with epilepsy. When monitoring is not feasible, clinicians may need to adjust doses based on seizure severity and the well-documented pharmacokinetic changes of specific medications such as lamotrigine, levetiracetam, oxcarbazepine. The goal is to maintain effective seizure control while minimizing teratogenic risks and ensuring safe fetal development.
