Valproate has long been a trusted ally in managing epilepsy and bipolar disorder, but recent findings have cast a shadow over its use, especially concerning pregnancy and fertility. The Medicines and Healthcare products Regulatory Agency (MHRA) has responded with a set of stringent new safety measures, aiming to mitigate these risks and protect patients. With evidence suggesting that exposure to valproate during pregnancy can lead to serious birth defects and neurodevelopmental disorders, the urgency for change is palpable.
These new guidelines are more than just recommendations; they represent a pivotal shift in how valproate is prescribed and managed. Understanding these changes is critical for healthcare professionals and patients to ensuring safe and effective treatment.
This blog will uncover the complexities of the MHRA's alert, offering insights into the new safety protocols and educational materials designed to support informed decision-making.
Key Takeaways
Background on Valproate
Valproate, known by brand names such as Belvo, Convulex, Depakote, and others, has been a mainstay in the treatment of epilepsy and bipolar disorder. However, its use comes with significant risks, particularly concerning pregnancy and fertility.
The Medicines and Healthcare products Regulatory Agency (MHRA) has issued new safety measures to address these concerns, aiming to protect patients while maintaining effective treatment options.
New Safety Measures and Educational Materials
The MHRA's latest alert introduces comprehensive safety measures and educational materials designed to minimise the risks associated with valproate. These measures are part of the National Patient Safety Alert and crucial for healthcare professionals and patients. The updated materials include:
Healthcare Professional Guide: This guide provides detailed information on the risks of valproate, particularly during pregnancy, and outlines the new prescribing conditions.
Patient Guide: This guide offers updated information on the risks of valproate and what actions patients need to take.
Annual Risk Acknowledgement Form (ARAF): Used to document discussions between patients and specialists about the risks of valproate, particularly for women of childbearing potential.
Advice for Healthcare Professionals
Healthcare professionals play a critical role in implementing these new safety measures. Key points include:
Prescribing Guidelines: Valproate must not be started in new patients under 55 unless two specialists agree there are no other effective treatments. This is crucial to minimise reproductive risks.
Annual Reviews: Women of childbearing potential should be reviewed annually using the revised ARAF valproate form. For continued treatment, a second specialist's signature is required.
Dispensing Practices: Valproate should be dispensed in the manufacturer's original full pack, and any adverse reactions should be reported using the Yellow Card system.
Patient Discussions: Use the updated safety and educational materials to support patient discussions, ensuring they are fully informed of the risks and treatment options.
Advice for Patients
For patients, understanding the new guidelines is essential to ensure safe and effective treatment. Key advice includes:
Do Not Discontinue Without Consultation: Stopping valproate suddenly can worsen epilepsy or bipolar disorder. Always consult a specialist before making changes to your medication.
Attend Appointments: Regular reviews are crucial to discuss your treatment plan and any concerns you may have.
Consult the Patient Guide: This resource provides valuable information about the risks of valproate and the necessary precautions.
Family Planning for Males: Male patients planning a family within the next year should discuss treatment options with a healthcare professional, as recent data suggests potential risks to offspring.

Valproate Treatment and Pregnancy Risks
Exposure to valproate during pregnancy is associated with a high risk of birth defects and neurodevelopmental disorders. The MHRA Valproate 2023 guidelines emphasise the importance of the Pregnancy Prevention Programme (PPP) for women of childbearing potential. Key points include:
Birth Defects and Neurodevelopmental Disorders: Up to 11% of babies exposed to valproate in utero may have physical birth defects, and 30-40% may develop neurodevelopmental disorders.
Pregnancy Prevention Programme: Since 2018, valproate has been contraindicated in women of childbearing potential unless they adhere to the PPP, which includes using effective contraception.
Recent Findings: The MHRA valproate 2024 update highlights new data suggesting an increased risk of neurodevelopmental disorders in children whose fathers took valproate before conception.
New Regulatory Safety and Educational Materials
To support the implementation of these measures, the MHRA has introduced several new materials:
Risk Acknowledgement Form for Males: This form supports discussions about the risks associated with valproate for male patients starting treatment.
Patient Card: Provides key information for female patients on contraception and pregnancy prevention.
Pharmacy Poster and Warning Stickers: These materials ensure that pharmacists know the necessary precautions when dispensing valproate.
Supporting Patient Discussions
Effective communication is vital in ensuring patients understand the risks and benefits of valproate treatment. Healthcare professionals should:
Use Individualised Language: Tailor discussions to each patient's needs and circumstances, ensuring they fully understand the implications of their treatment.
Utilise Additional Resources: The safety and educational materials should be used alongside other resources, such as NHS patient support tools and guidelines from the Association of British Neurologists.
Conclusion
The MHRA's new safety measures for valproate represent a significant step forward in protecting patients while ensuring effective treatment. By understanding and implementing these guidelines, healthcare professionals can help minimise risks and support informed decision-making. Patients, too, must stay engaged and informed, attending regular reviews and consulting available resources.
Together, these efforts will help ensure the safe use of valproate, safeguarding the well-being of current and future generations.
