To investigate antiepileptic drugs (AEDs) prescription and pregnancy outcomes in pregnancies with epilepsy in Taiwan between 2004 and 2015. We retrospectively reviewed data from the Taiwanese Registry of Epilepsy and Pregnancy (TREP). The TREP registry is a voluntary prospective cohort registry, which tracks pregnant women with epilepsy and AED prescription throughout pregnancy, delivery, and early childhood development. All TREP pregnancies (n = 318) that had completed questionnaires up until delivery or had had an unsuccessful pregnancy were analyzed. Over 94.7% of women had been prescribed AEDs during pregnancy, with 69.0% and 25.7% having received monotherapy, or polytherapy, respectively. Among live births, 12 (3.9%) reported malformation. Cesarean section rate was reported higher than usual (54.5%). In 2004, 73.3% of AEDs prescribed were 1st generation, with 1st generation prescription rates falling to only 8.3% of total prescribed in 2015. AED polytherapy also fell during the study period (40.0% to 20.0%). Cesarean sections were found to be higher for women over 35 years, who had generalized epilepsy, or had experienced an obstetric complication during pregnancy term. Binary logistic regression revealed that Cesarean section was associated with maternal complications (OR = 5.11, CI 95% = 1.11–23.51, p = 0.036), while malformations were associated with obstetric complication (OR = 20.46, CI 95% = 4.80–87.21, p<0.001). Both AED risk types were not associated with complications or malformations. Our sample provides a unique insight into the women with epilepsy with AED use during pregnancy. Cesarean section rate was observed to be higher than usual, but malformation rates remained low. Results indicate a decrease in both 1st generation AEDs and proportion of patients receiving polytherapy over the study period. Obstetric complications were associated with Cesarean section. Fetal malformations were significantly associated with obstetric complications. AED risk factors were not significantly associated with either complications or malformations.
