Compared to women without epilepsy, women with epilepsy and [antiepileptic drug] use had an increased risk of mild pre-eclampsia [1.8: (1.3-2.4)], gestational hypertension [1.5: (1.0-2.2)], vaginal bleeding late in pregnancy [1.9: (1.1-3.2)], and delivery before 34 weeks of gestation [1.5: (1.1-2.0)]. No significant increase in the risk of these complications was observed in women with epilepsy not using [anti-epileptic drugs].
So it looks like the drugs they use for epilepsy therapy can raise risk of preeclampsia -- talk to your docs!
