Valproate (Epilim) guidelines

Sodium Valproate medication and its packaging.


Sodium Valproate (Epilim) is a medicine licensed in Ireland to treat epilepsy and bipolar disorder. If a woman becomes pregnant while taking Epilim, their baby is at risk of serious birth defects and developmental disorders. In 30-40% of cases where the child has been exposed to valproate in utero, the child will have serious developmental disorders. In 10% of cases, the child will have congenital malformations. The HSE estimate that up to 1,250 families have been impacted in these ways by exposure to valproate in pregnancy since the 1970s.

Preventative Measures

In February 2018, the European Medicines Agency (EMA) put in place measures to reduce the risk of exposure of babies to Epilim in the womb.

These measures are implemented in Ireland by the medicines regulator, the HPRA ,and include:

  • For women with epilepsy, Epilim must not be used in pregnancy unless there is no suitable alternative treatment.
  • In female patients from the time they become able to have children, Epilim must not be used unless the conditions of a Pregnancy Prevention Programme are met.

What are the main points of the Pregnancy Prevention Programme?

  • Prescribers must assess female patients for the potential of becoming pregnant, and involve the patient in evaluating her individual circumstances and supporting informed decision making,
  • Pregnancy tests must be carried out before starting and during treatment as needed,
  • Female patients must be informed about the risks of Epilim and what to do if planning a pregnancy or becomes pregnant
  • Effective contraception must be used throughout treatment and counselling on contraception provided
  • All female patients must be given the new patient information booklet and must sign an annual Risk Acknowledgement form acknowledging that they understand the risks and necessary precautions
  • Importantly, all female patients must have an annual review of treatment by a specialist.If you are not currently attending specialist services, please contact your GP for advice and guidance in order to schedule a specialist review.
