Valproate : le formulaire d’accord de soins utilisé seulement une fois sur deux

Médicaments contenant du valproate : le niveau d’application des conditions de prescription et de délivrance est insuffisant

Plusieurs mesures ont été mises en place par l’ANSM depuis 2015 afin de réduire les risques liés à l’utilisation pendant la grossesse des médicaments contenant du valproate ou un dérivé (Depakine, Depakine Chrono 500, Micropakine, et génériques, Depakote, Depamide) et en particulier une démarche sécurisée de prescription et de délivrance. Cette démarche repose sur la présentation en pharmacie pour les patientes d’un formulaire d’accord de soin co-signé avec le médecin spécialiste associé à une ordonnance de ce spécialiste datant de moins d’un an. L’ANSM, en collaboration avec l’Ordre des pharmaciens, a demandé à Sanofi de réaliser une étude pour s’assurer de la bonne application de ces conditions de prescription et de délivrance (CPD).

” … le respect des conditions de prescription et délivrance était de l’ordre de 31% en 2016. Il n’atteint que 47% en 2017. … Le formulaire d’accord de soins n’était présenté que pour 50% des dispensations en 2017 (33% en 2016)… ”

Les résultats de l’étude montrent que les CPD ne sont pas suffisamment respectées.

“Actuellement, tout n’est pas fait pour éviter le valproate chez la femme enceinte. Il faut que l’information soit la plus répandue possible”

Dominique Martin, directeur général de l’ANSM.

L’utilisation des médicaments contenant du valproate ou un dérivé nécessite une attention particulière de l’ensemble des professionnels de santé et une information complète des patientes. En effet, ces médicaments présentent des risques importants de malformation et de troubles neuro-développementaux pour les enfants s’ils sont utilisés pendant la grossesse.

Valproate Drug Harms : EMA Public Hearing in London

Many pregnant women are still unaware of epilepsy drug risks

The public hearing was part of a review of the safety of using valproate-containing medicines in women and girls who are pregnant or of childbearing age by EMA’s Pharmacovigilance Risk Assessment Committee (PRAC). There is a risk of malformations and neurodevelopmental problems in babies who are exposed to valproate in the womb, and the review follows concerns that European Union (EU)-wide risk minimisation measures currently in place do not seem to be sufficiently effective.

Warnings to young women who might become pregnant that the epilepsy drug sodium valproate could cause birth defects and developmental problems in their babies could have been made public more than 40 years ago, according to campaigners.

EMA Public Hearing about Drug Valproate Use in Pregnancy

Pregnant women still unaware of epilepsy drug risks

Was there a deliberate decision not to publish Valproate’s risks ?

The public hearing was part of a review of the safety of using valproate-containing medicines in women and girls who are pregnant or of childbearing age by EMA’s Pharmacovigilance Risk Assessment Committee (PRAC). There is a risk of malformations and neurodevelopmental problems in babies who are exposed to valproate in the womb, and the review follows concerns that European Union (EU)-wide risk minimisation measures currently in place do not seem to be sufficiently effective.

Epilepsy drug warnings DO NOT reach enough women, 2017 survey finds

Almost 70% of women surveyed about a powerful epilepsy drug have not received new safety warnings about the dangers of taking it during pregnancy

Two thirds of women who take the antiepileptic drug sodium valproate said they had not received new safety warnings about the dangers of taking it during pregnancy, a survey carried out by epilepsy charities has found. A similar survey last year found that half of women taking the drug were unaware it could harm their fetus.

The new results are to be presented at a public hearing on the safety of valproate drugs organised by the European Medicines Agency on 26 September in London. …

Valproate Medicines in Female Patients: MHRA Toolkit on the Risks

Being better informed about the risks of taking valproate medicines during pregnancy

Valproate is a treatment for epilepsy and bipolar disorder and is prescribed to thousands of women. Since its introduction in 1974, the product information for doctors has included a warning about the possible risk of birth defects. As the risks to unborn children have been increasingly understood, the warnings have been strengthened.

The risk of developmental disorders is up to 4 in 10 and the risk of birth defects is approximately 1 in 10. The risk for autism, ASD and ADHD is higher for children exposed in-utero.

MHRA has worked with industry, healthcare professionals and patient groups on a toolkit to ensure female patients are better informed about the risks of taking valproate medicines during pregnancy.

In women who take valproate while pregnant, around 1 in 10 babies will have a birth defect.

Birth defects seen when mothers take valproate during pregnancy include:

  • spina bifida (where the bones of the spine do not develop properly)
  • facial and skull malformations (including cleft lip and palate, where the upper lip or facial bones are split)
  • malformations of the limbs, heart, kidney, urinary tract and sexual organs.

In women who take valproate while pregnant, about 3–4 children in every 10 may have developmental problems. The long-term effects are not known.

The effects on development can include:

  • being late in learning to walk and talk
  • lower intelligence than other children of the same age
    poor speech and language skills
  • memory problems.

Children exposed to valproate in the womb are more likely to have autism or autistic spectrum disorders (ASD). There is also some evidence children may be more likely to be at risk of developing symptoms of attention deficit hyperactivity disorder (ADHD).

MHRA February 2016 advice

Valproate should not be used in female children, in female adolescents, in women of childbearing potential and in pregnant women unless other treatments are ineffective or not tolerated. Women of childbearing potential must use effective contraception during treatment.

No-one should stop taking valproate without discussing it first with their doctor and the benefits of valproate treatment must be carefully balanced against the risks.

If valproate is the only option, women of childbearing age should be given effective contraception. Women taking valproate must have regular reviews of their treatment.

Better understanding of the risks of valproate medicines and pregnancy

New toolkit by The Medicines and Healthcare products Regulatory Agency (MHRA)

A toolkit to ensure female patients are better informed about the risks of taking valproate medicines during pregnancy has been launched.

The Medicines and Healthcare products Regulatory Agency (MHRA) today welcomed the launch of a new toolkit to ensure female patients are better informed about the risks of taking valproate medicines during pregnancy.

Valproate (Epilim, Depakote and other generic brands) is a treatment for epilepsy and bipolar disorder and is prescribed to thousands of women. It is associated with a risk of birth defects and developmental disorders in children born to women who take valproate during pregnancy.

MHRA strengthened warnings on the risks of valproate in pregnancy last year, as understanding of the extent of these risks had increased. Up to 4 in 10 babies are at risk of developmental disorders, and approximately 1 in 10 are at risk of birth defects, if valproate is taken during pregnancy. The new toolkit addresses concerns that the risks of valproate are not being adequately explained to female patients.

Developed in consultation with stakeholders including healthcare professional and patient groups, the toolkit includes a credit card sized patient card to be issued by pharmacists, booklets for healthcare professionals and for patients together with a checklist of important questions and discussion points to be kept with the patient’s file. Warnings will appear on the medicine’s packaging later this year.

The MHRA is asking GPs, pharmacists, neurologists, psychiatrists, and other relevant healthcare and mental health professionals to use the toolkit to help facilitate discussion of the risks with their patients.

Cognitive and behavioral outcomes following fetal exposure to valproate and antiepileptic drugs

Fetal antiepileptic drug exposure: Adaptive and emotional/behavioral functioning at age 6 years

image of staring-child
The NEAD study is the largest prospective investigation of cognitive and behavioral outcomes following fetal exposure to valproate, carbamazepine, lamotrigine, and phenytoin. Children of mothers who took valproate during their pregnancy were at a significantly greater risk for a diagnosis of ADHD. the look.

2015 Study Abstract

The Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) study is a prospective observational multicenter study in the USA and UK, which enrolled pregnant women with epilepsy on antiepileptic drug (AED) monotherapy from 1999 to 2004. The study aimed to determine if differential long-term neurodevelopmental effects exist across four commonly used AEDs (carbamazepine, lamotrigine, phenytoin, and valproate).

In this report, we examine fetal AED exposure effects on adaptive and emotional/behavioral functioning at 6 years of age in 195 children (including three sets of twins) whose parent (in most cases, the mother) completed at least one of the rating scales.

Adjusted mean scores for the four AED groups were in the low average to average range for parent ratings of adaptive functioning on the Adaptive Behavior Assessment System-Second Edition (ABAS-II) and for parent and teacher ratings of emotional/behavioral functioning on the Behavior Assessment System for Children (BASC). However, children whose mothers took valproate during pregnancy had significantly lower General Adaptive Composite scores than the lamotrigine and phenytoin groups. Further, a significant dose-related performance decline in parental ratings of adaptive functioning was seen for both valproate and phenytoin. Children whose mothers took valproate were also rated by their parents as exhibiting significantly more atypical behaviors and inattention than those in the lamotrigine and phenytoin groups. Based upon BASC parent and teacher ratings of attention span and hyperactivity, children of mothers who took valproate during their pregnancy were at a significantly greater risk for a diagnosis of ADHD.

The increased likelihood of difficulty with adaptive functioning and ADHD with fetal valproate exposure should be communicated to women with epilepsy who require antiepileptic medication. Finally, additional research is needed to confirm these findings in larger prospective study samples, examine potential risks associated with other AEDs, better define the risks to the neonate that are associated with AEDs for treatment of seizures, and understand the underlying mechanisms of adverse AED effects on the immature brain.

Valproate et dérivés (Dépakine®, Dépakote®, Dépamide®, Micropakine® et génériques) : Rappel de l’échéance du 31 décembre relative à la mise en application des nouvelles conditions de prescription et de délivrance.

Lettre aux professionnels de santé – ANSM 26/11/2015

Information destinée aux spécialistes en neurologie, psychiatrie, pédiatrie (expérimentés dans la prise en charge de l’épilepsie), médecins généralistes, gynécologues, gynécologues-obstétriciens, pharmaciens, centres de planning familial, sages-femmes, services de PMI

Les spécialités à base de valproate et dérivés ne doivent pas être prescrites chez les filles, adolescentes, femmes en âge de procréer et femmes enceintes, sauf en cas d’inefficacité ou d’intolérance aux alternatives médicamenteuses.

Après le 31 décembre 2015, aucune délivrance de ces spécialités ne pourra se faire aux patientes sans présentation :

  • de la prescription initiale annuelle par un spécialiste ;
  • et du formulaire d’accord de soins signé.

Les patientes en âge de procréer ou susceptibles de l’être un jour et actuellement traitées par ces spécialités doivent donc consulter un médecin spécialiste dans les meilleurs délais (si cela n’a pas déjà été fait), afin qu’il réévalue la nécessité du traitement et qu’il leur fasse signer un accord de soins en cas de maintien du traitement.
