That was probably the first research paper to suggest that it was not just coincidence and that there was a causal relationship, which is why it is seen as definitive.

The pharmaceutical company Sanofi, which many Members have mentioned, has stated that it has kept in line with scientific knowledge when reporting side-effects in a foetus. However, from as early as 1983 the CSM and the MHRA reported the problems caused by taking sodium valproate in pregnancy, but did not insist that Sanofi issue warnings in the form of a patient information leaflet.

Even now, to this day, epilepsy charities report that women are not aware of the potential risks when taking the drug in pregnancy. A survey has shown—I know it has already been mentioned, but it does no harm to reinforce these findings—that 18% of women taking sodium valproate were not aware of the risks during pregnancy, and 28% said that they had not been informed of any risks. That is despite the production by the MHRA of a valproate toolkit designed to help healthcare professionals to talk to women with epilepsy about the risks of taking valproate during pregnancy.
