  • Valproate treatment should only be commenced and supervised by a doctor experienced in managing epilepsy and bipolar disorder in female patients.
  • Before initiating treatment, the balance of the benefits of treatment with valproate must be weighed against the risks. This should be considered at routine treatment reviews, when a female reaches puberty and when a woman plans a pregnancy or becomes pregnant.

  • The valproate patient guide (below) and patient card should be provided to all female patients of child-bearing age and discussed with them to ensure full understanding of the associated risks.
