Several studies have observed that fetal exposure to the antiepileptic drug (AED), valproic acid (Depakote), may significantly increase the risk of having a child with an autism spectrum disorder. In contrast, exposures to other AEDs, [...]
This is a paper I missed from 2014, but I think this study adds some important information to the review we posted on topiramate a few weeks ago.
The European Medicine Agency (EMA)'s Pharmacovigilance and Risk Assessment Committee recently recommended strengthening the restrictions on the use of valproic acid in women of reproductive age. Over the last few years, we have seen a host of articles documenting the deleterious effects of valproic acid on the developing fetus:
Autism spectrum disorders (ASDs), which include childhood autism, autistic disorder, Asperger syndrome, atypical autism, and other pervasive developmental disorders, are characterized by social and communication difficulties and by stereotyped or repetitive behaviors and interests. It [...]
Because breastfeeding has many psychological and medical benefits for both the mother and her child, many women would like to breastfeed. However, all medications taken by the mother are secreted into the breast milk. While various studies have addressed the short-term safety of antiepileptic drugs (AEDs) in nursing infants, none have systematically assessed the long-term effects of exposure to these drugs on cognitive development.
An increasing number of reproductive age women now take newer anticonvulsants for the treatment of mood and anxiety disorders; however, information regarding the reproductive safety of these medications is limited. A recent study has evaluated the cognitive and language development of children born to women with epilepsy exposed in utero to levetiracetam (LEV, Keppra) or sodium valproate (VPA, Depakote), as compared to control children born to women without epilepsy not taking medication during pregnancy.
We have previously written about studies which indicate that prenatal exposure to antiepileptic drugs (AEDs), particularly valproic acid, may adversely affect the developing fetus. Numerous studies have documented long-term effects of antiepileptic exposure on cognitive functioning: prenatal exposure to AEDs has been associated with lower IQs, as well as lower scores on tests of executive functioning, memory, verbal and nonverbal abilities, in children at 6 yeas of age (Meador KJ et al, 2012). These deficits were the most prominent in children exposed to valproic acid.
There have been multiple recent reports indicating that the use of valproate during pregnancy may be associated with lower IQ, cognitive problems, and developmental delays in exposed children. This has prompted the FDA to issue a warning regarding the use of valproate-containing drugs, including Depakote and Depakene, during pregnancy:
There have long been concerns regarding the use of the anticonvulsant valproate (Depakote, VPA) 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 and other organ systems. Multiple reports have also indicated that in utero exposure to valproate may also negatively affect cognitive development.
