French pharmaceutical firm Sanofi is being investigated for possible manslaughter charges in France over the deaths of four babies whose mothers took the anti-epilepsy drug valproate
Marketed in France as Depakine, it was found to carry a high risk of birth defects if taken by pregnant women
It is already being prosecuted in France for allegedly providing misleading information about the drug
It has been known for many years that the drug should not be given to pregnant women, because of the high risk of congenital malformations or autism in their babies
