Men on Valproate Advised to Use Contraception Due to Potential Risks to Children
In a warning that has significant implications for men undergoing treatment for epilepsy and bipolar disorder, the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has advised those taking sodium valproate to use effective contraception. The advisory stems from new data indicating a small increased risk of neurodevelopmental disorders in children conceived by men on this medication. This precautionary measure is vital, not just for men, but for their partners who may become pregnant.
Why the Warning Was Issued
The alert was prompted by the results of a retrospective observational study based on data from Scandinavia, which suggested that about 5% of children born to fathers taking sodium valproate may face neurodevelopmental challenges. This is compared to 3% in children born to men treated with alternative medications, such as lamotrigine or levetiracetam. Although the study does not establish causation, the findings are deemed significant enough to warrant precautionary action.
Understanding Sodium Valproate
Sodium valproate, known under several brand names including Epilim and Depakote, is widely prescribed for epilepsy and bipolar disorder. Despite its efficacy, the MHRA cautions that it is essential for patients to consult their doctors before making any changes to their medication regimen. The guidance outlines that men should refrain from donating sperm while on the drug, and for three months after cessation.
Potential Risks to Offspring
Prior understanding of sodium valproate indicated risks primarily when women took the medication during pregnancy. Research has highlighted that children exposed to sodium valproate in utero are at a heightened risk—30-40% for serious developmental disorders and about 10% for congenital malformations. The new findings extend this concern, linking paternal usage to potential neurodevelopmental disorders in future children.

Voices from the Healthcare Community
Clare Pelham, Chief Executive of the Epilepsy Society, welcomed the MHRA’s decision but expressed concern over the timing of the announcement. “While it is essential that these risks come to light, more decisive actions could have been taken sooner,” she stated. The Epilepsy Society and similar organizations advocate for transparent communication of risks, enabling patients to make informed choices.
Feedback from Affected Families
Families affected by valproate have long voiced concerns about the potential impact of the drug on their children. Karen Buck, a spokesperson from a support group for families impacted by valproate, criticized the MHRA for their delayed response to male-related safety issues. Her daughter has been severely affected by Fetal Valproate Syndrome, highlighting the grave consequences of this medication. “This is shameful. I warned them years ago about the risks faced by families, and it is disappointing to see only now they are acting on this,” Buck said.
Recommendations for Patients
The MHRA emphasizes that men currently on sodium valproate should not stop taking the medication without consulting a healthcare professional first. Patients are encouraged to attend their routine appointments for discussions regarding their treatment and any potential alternatives available. The agency’s Chief Safety Officer, Dr. Alison Cave, further reinforces that while the risks for children conceived while the father is on valproate are lower than those for mothers on the drug, it remains crucial to follow the updated guidelines to protect future generations.
The Bigger Picture
This advisory comes in addition to recommendations issued earlier this year, which limited the prescription of sodium valproate to men and women under 55, signifying a growing recognition of the drug’s reproductive risks. With approximately 65,000 males in the UK currently on sodium valproate, the MHRA’s cautious approach underscores the need for ongoing monitoring of the medication’s impact on patients and their families.
As healthcare providers continue to navigate the complexities surrounding the use of sodium valproate, the call for informed consent and comprehensive risk communication remains imperative. Families and patients affected by valproate are urged to keep up with the latest information and engage their healthcare teams in conversations about their treatment options.
