The AAN/AES guidelines state that pregnancy probably increases the clearance and decreases the concentration of lamotrigine, phenytoin, and, to a lesser extent, carbamazepine and that it possibly decreases the level of levetiracetam and the active oxcarbazepine metabolite, the monohydroxy derivative. They state that monitoring of lamotrigine, carbamazepine, and phenytoin levels during pregnancy should be considered and suggest that monitoring of levetiracetam and oxcarbazepine levels may be considered.
