A scandal worse than thalidomide
Doctors knew in 1973 that the epilepsy drug sodium valproate posed a risk to unborn children — and ordered that warnings be removed from packets. Almost 50 years and 20,000 disabled babies later, it is still being prescribed to pregnant women
When sodium valproate was introduced as a new epilepsy drug in the 1970s, the British medical community was still reeling from that very scandal — in which hundreds of babies were born severely deformed after pregnant women were given thalidomide.
The UK’s newly formed Committee on Safety of Medicines had been designated as the key decision-making body on new medicines.
This committee — whose membership comprised some of the UK’s leading medics and was chaired by Sir Eric Scowen, professor of medicine at St Bartholomew’s Hospital in London — met to discuss sodium valproate on multiple occasions in 1972 and 1973.
They noted that the drug had shown enormous promise in controlling the terrible seizures suffered by patients, even for those whose epilepsy had proven resistant to other treatments.
Sodium valproate is still a safe and effective drug for sufferers of epilepsy, who should not stop taking it without first discussing this with their doctor.
However, the notes of the meeting show that the manufacturers, Sanofi, had raised to the committee that there were signs in animal tests that valproate could potentially be teratogenic — harmful to foetuses.
The committee concluded that the use of anti-seizure drugs such as sodium valproate was indeed “liable to produce” abnormalities. But they stated that “the risk appears to be low, and not sufficient to justify stopping the use” of the drug.
In a decision that would have disastrous consequences for thousands of families, the committee chose not to alert the public to the concerns that the drug could harm babies — concluding that since the evidence was not clear, doing so would risk causing “fruitless anxiety” to patients.
They specified that warnings should be provided to doctors, “but not on package inserts, so that there would be no danger of patients themselves seeing it”.
The committee’s decision not to warn women of the risks was probably “influenced by the paternalistic nature of society at the time”, believes Dr Rebecca Bromley, a paediatric neuropsychologist at the University of Manchester.
She believes the committee did not appear to consider the need for “women to have an informed say in their treatment”. Instead, the effect of the decision was to “leave patients fully in the dark about the risk that their medicine might carry”.

As a result, about six babies every month are being born in the UK having been exposed to the drug.
An investigation by The Sunday Times has found that the drug is still being handed out to women in plain packets with the information leaflets missing, or with stickers over the warnings.
