Women who took epilepsy medication while pregnant are suing for damages, claiming the drug harmed their children. They have foetal anti-convulsant syndrome (FACS), which can involve physical and learning difficulties. Lawyers argue the women had to choose between taking the drug, risking side effects - and not, risking seizures. Sanofi-Synthelabo, which makes the drug, said the risks associated with the drug were well-known to doctors. It says there could be a range of causes for the congenital abnormalities, not just exposure to anti epileptic drugs during pregnancy.
