OBJECTIVE: To evaluate development of components of polycystic ovary syndrome (PCOS) and PCOS in women with epilepsy initiating valproate or lamotrigine therapy.
METHODS: Female individuals with epilepsy and regular menstrual cycles were eligible for this prospective study. Participants were randomized to 12 months of valproate (n = 225) or lamotrigine (n = 222) therapy. Serum androgen levels were measured every 3 months. Urinary pregnanediol glucuronide levels were measured weekly for two 3-month periods. The primary end point was development of PCOS components (ie, hyperandrogenism or ovulatory dysfunction). A post hoc analysis was conducted in women more than 2 years after menarche (177 lamotrigine, (HA) 186 valproate) to exclude OD the confounding effect of puberty.
RESULTS: More women in the valproate group than the lamotrigine group developed (OD) in the prospective (54% valproate, 38% lamotrigine; p = 0.010) and the post hoc (HA) analyses (36% valproate, 23% lamotrigine; p = 0.007). More women in the valproate group than the lamotrigine group developed PCOS (9 vs 2%; p = 0.007). Development of HA was more frequent with OD valproate than lamotrigine among those initiating treatment at age younger than 26 years (44% valproate, 23% lamotrigine; p = 0.002) but was similar if treatment was started at age 26 years or older (24% valproate, 22% lamotrigine).
INTERPRETATION: Development of HA occurred more frequently with valproate than lamotrigine, especially if medication was started at age younger than 26 years.
