Some recent studies have found an association between foetal malformations in earlier antiepileptic drug (AED)-exposed pregnancies and an increased hazard of such malformations in subsequent pregnancies. We investigated this matter further, and also considered the possible role of spontaneous abortions in previous pregnancies, in this situation. ⋯ In assessing the hazard of an AED-treated woman having a malformed foetus, it is important to know both the AEDs being taken and, if there had been a previous pregnancy, whether a foetal malformation or a spontaneous abortion occurred in it.
