    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.     

    Can Paxil (Paroxetine) Be Used While Breastfeeding?

    All medications are secreted into the breast milk, although concentrations appear to vary. There is a fair amount of information on the use of Paxil (paroxetine) in nursing women. While Paxil may be detected in the breast milk, there have been no reports of adverse events in the nursing infant. The only situation where one may want to avoid breastfeeding is when the baby is premature or has signs of hepatic immaturity, which may make it more difficult for the infant to metabolize the medication to which he or she is exposed. Premature babies are also probably more vulnerable to the toxic effects of these medications.

    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.

    Anticonvulsants During Pregnancy in Women with Bipolar Disorder

    Unfortunately the mood stabilizers most commonly used to treat bipolar disorder (including lithium and valproic acid) can increase the risk of certain types of congenital malformations in children exposed to these medications during the first trimester of pregnancy. For women who need a mood stabilizer during pregnancy, lithium is the safest option; however, when used during the first trimester, it carries a 0.1% risk of a cardiac malformation called Ebstein's anomaly. Although this is a potentially serious complication, it is important to keep in mind that the risk of malformation is relatively small.
