    From the North American AED Pregnancy Registry: The Newer Anticonvulsants Appear to Be Safer

    While it is well-established that several of the older anticonvulsants, including valproate (Depakote), carry a significant teratogenic risk, less is known about the reproductive safety of the newer antiepileptic drugs (AEDs). The North American AED Pregnancy Registry was established in 1997 for pregnant women in the United States and Canada at the Massachusetts General Hospital. The purpose of the registry is to obtain and publish information on the frequency of major malformations among infants whose mothers have taken one or more AEDs during pregnancy.

    Fetal Exposure to Valproate Associated with Lower IQ

    There have long been concerns regarding the use of the anticonvulsant valproate (Depakote) during pregnancy.  First trimester use of valproate has been associated with a 3-5% risk of neural tube defects, as well as an increased risk of other malformations affecting the heart, limbs, and genitals. A recent report published in the New England Journal of Medicine indicates that in utero exposure to valproate may also result in lower IQ.     

    Medication Changes During Pregnancy

    At our clinic we have the opportunity to see patients at various stages of pregnancy. When we evaluate a patient while she is still in the planning stages, we may recommend changing medications to those that have a better studied safety profile during pregnancy and see how she does on those medications prior to conception. If that same patient came into our clinic for an evaluation, but was already pregnant, we may make different recommendations than if she was in the planning stages.

    Polycystic Ovarian Syndrome in Women Taking Valproate

    Polycystic ovarian syndrome (PCOS) occurs in 4-7% of women and is characterized by irregular menstrual cycles and hyperandrogenism (facial hair, acne, male-pattern hair loss, acne, or elevated male hormone levels). The majority of women with PCOS also suffer from obesity and insulin resistance. PCOS has been associated with a spectrum of health problems including infertility, diabetes, and possibly heart disease and endometrial cancer. Recently there has been concern that women with bipolar disorder who are treated with the mood stabilizer valproate (VPA; brand name Depakote or Depakene), may be at higher risk for PCOS, although the data have been somewhat conflicting.
