Overview

Objective Antiseizure medications (ASMs) remain the mainstay of epilepsy treatment. These ASMs have mainly been tested in trials in adults with epilepsy, which subsequently led to market authorization (MA). For treatment of – especially young – children with epilepsy, several ASMs do not have a MA and guidelines are lacking, subsequently leading to “off‐label” use of ASMs. Even though “off‐label” ASM prescriptions for children could lead to more adverse events, it can be clinically appropriate and rational if the benefits outweigh the risks. This could be the case if “on‐label” ASM, in mono‐ or polytherapy, fails to achieve adequate seizure control. Methods The Medical Therapies Task Force of the International League Against Epilepsy (ILAE) Commission for Pediatrics performed a survey to study the current treatment practices in six classic, early life epilepsy scenarios. Our aim was not only to study first‐ and second‐line treatment preferences but also to illustrate the use of “off‐label” drugs in childhood epilepsies. Results Our results reveal that several ASMs (e.g. topiramate, oxcarbazepine, benzodiazepines) are prescribed “off‐label” in distinct scenarios of young children with epilepsy. In addition, recent scientific guidelines were not always adopted by several survey respondents, suggesting a potential knowledge gap. Significance We report the relatively common use of “off‐label” prescriptions that underlines the need for targeted and appropriately designed clinical trials, including younger patients, which will also result in the ability to generate evidence‐based guidelines.
