Sodium valproate compensation and medical negligence claims

Sodium valproate is a medication used to treat conditions such as epilepsy, bipolar disorder and migraines. It is known by brand names including Epilim, Episenta and Depakote.

Whilst it has been valuable medication in the past, there are now better and safer alternatives and for decades, evidence has shown that sodium valproate can cause serious harm when taken during pregnancy. Thousands of children have been born with physical disabilities and lifelong developmental conditions after exposure to the drug in utero.

At Russell-Cooke, our medical negligence solicitors advise parents, families and affected individuals on compensation claims relating to sodium valproate, including claims arising from failures in prescribing, counselling, and informed consent.

How sodium valproate can affect unborn children

Medical research has long linked sodium valproate exposure during pregnancy to a significantly increased risk of harm to unborn babies.

Children exposed to sodium valproate in utero may be born with, or later diagnosed with:

  • cleft lip and/or palate

  • skeletal and limb abnormalities

  • facial or skull malformations

  • heart defects

  • kidney or urinary tract problems

  • developmental delay

  • learning disabilities

  • autism spectrum conditions

Many families were not warned of these risks at the time the medication was prescribed or continued.

When might there be a medical negligence claim?

A medical negligence claim may arise where healthcare professionals failed to take reasonable steps to protect patients and unborn children from avoidable harm.

This can include situations where:

  • sodium valproate was prescribed to a woman of child bearing age without adequate warning of pregnancy related risks

  • the risks were not properly explained before or during pregnancy

  • alternative medications were not discussed or explored

  • prescribing continued despite known guidance and warnings

  • there was a failure to review or update treatment plans over time

Each case turns on its own facts, and specialist advice is essential.

Redress schemes and compensation claims: what’s the difference?

In February 2024, the Patient Safety Commissioner for England published The Hughes Report, which recommended the introduction of redress schemes for those harmed by pelvic mesh and sodium valproate.

The report made clear that:

  • redress schemes would not mirror court awarded compensation

  • any payment under such schemes may represent only a contribution towards losses

  • final decisions rest with government ministers

More than two years on, no formal redress scheme for sodium valproate is yet in place.

In contrast, compensation through medical negligence litigation follows an established legal framework.

If negligence is proven, the courts aim to award compensation that reflects:

  • the pain and suffering caused by injury

  • financial losses incurred as a direct result of the harm

  • future care, treatment and support needs

For many families, a legal claim may currently be the only realistic route to financial redress.

Time limits for bringing a sodium valproate claim

Strict time limits apply to medical negligence claims.

In most cases, court proceedings must be started within three years of:

  • the negligent treatment, or

  • the date when the injured person first became aware that the harm may have been caused by negligence (the “date of knowledge”)

Because sodium valproate related harm may not have been apparent at birth, this later date of knowledge can be particularly important. However, as the damage has been caused to the unborn baby the 3 year time period does not begin until the child’s 18th birthday.

Where the extent of the damage is such that the child never gains sufficient mental capacity to bring a claim by themselves, claims are subject to different rules, and time limits may be extended or dispensed with in certain circumstances. Specialist advice should be sought as early as possible.

Frequently asked questions about sodium valproate compensation

There is no fixed amount of compensation for sodium valproate claims.

Awards are assessed on an individual basis and are influenced by factors such as:

  • the type and severity of the condition

  • the level of care and support required

  • the projected impact on education, independence and employment

  • life expectancy and future needs

High value claims involve obtaining expert medical and care evidence to ensure future needs are properly assessed.

In most medical negligence claims, court proceedings must be issued within three years of :

  • the negligent treatment, or

  • the date when the claimant first became aware that the harm may have been caused by negligent care (the “date of knowledge”).

Children’s claims follow different rules, and deadlines can depend on individual circumstances. Time limits can be complex in sodium valproate cases, so early advice is particularly important.
