Study description

The use of valproate by male patients during the three months before conception has recently drawn attention due to concerns about a potential increase in the risk of neurodevelopmental disorders (NDDs) in their offspring. Following a review of pertinent data, the European Medicines Agency's (EMA) safety committee, the Pharmacovigilance Risk Assessment Committee (PRAC), has advised caution in prescribing these medicines. However, this recommendation is based on limited, unpublished data and the findings have not yet been replicated.
Therefore, this study aims to investigate the association between paternal exposure to valproate and the risk of NDDs in two distinct populations, Norway and Taiwan, to provide more comprehensive evidence.
