Valproate not to be prescribed without a pregnancy prevention programme

News 24 April 2018

The Medicines and Healthcare products Regulatory Agency (MHRA) has today announced that valproate medicines – used to treat epilepsy and bipolar disorder – must no longer be prescribed to women of child bearing age unless she is on a pregnancy prevention programme (PPP).

The medication significantly increases the risk of birth defects and developmental disorders in children born to women who take it during pregnancy. Up to 4 in 10 babies are at risk of developmental disorders, and around 1 in 10 are at risk of birth defects.

Healthcare professionals who prescribe valproate must ensure sure the women is enrolled in a PPP, which includes the completion of a signed risk acknowledgement form and seeing a specialist at least every year.

These new regulatory measures are being supported across the NHS with other authorities also making changes – such as new GP system computer alerts – to ensure changes in prescribing behaviour take place promptly. Women who are prescribed valproate are encouraged to contact their GP and arrange to have their treatment reviewed. Women should not stop taking valproate without medical advice.

Mr Edward Morris, Vice President for Clinical Quality at the Royal College of Obstetricians and Gynaecologists (RCOG), said:

“We welcome this action to reduce the risk of physical and developmental problems in children born to mothers who have taken valproate during pregnancy. Our clinical guideline on the management of epilepsy in pregnancy recommends that exposure to sodium valproate and other anti-epileptic drugs should be minimised by changing the medication prior to conception, as recommended by an epilepsy specialist after a careful evaluation of the potential risks and benefits.

“It’s important to note that stopping medication for long-term conditions completely or altering the dose can pose a serious risk to both mother and baby. Women are advised to seek advice from their GP and/or specialist team before conception or as soon as they are aware that they are pregnant. For women with epilepsy, the lowest effective dose of the most appropriate anti-epileptic drug should be prescribed and they should be looked after by a specialist team throughout pregnancy.”
