Study description

A case-malformed control study evaluating the risk of orofacial clefts in relation to first trimester exposure to the the new anti-epileptic drug (AED) lamotrigine was conducted using data from 19 EUROCAT registries covering a population of 4 million births, 1995-2005. The study found no evidence of a specific increased risk of isolated orofacial clefts relative to other malformations due to lamotrigine monotherapy. This study was conducted following a US Federal Drugs Agency alert in 2006 concerning an increased risk of orofacial cleft associated with lamotrigine exposure.
