Lidocaine 5%-medicated plaster (Versatis) for localised neuropathic pain: results of a multicentre evaluation of use in children and adolescents.

Abstract

The Lidocaine 5% plaster is licensed for the symptomatic relief of neuropathic pain associated with post-herpetic neuralgia in adult patients over 18 years of age. Studies in adults also demonstrate efficacy of Lidocaine 5% plasters in other neuropathic pain conditions. Case reports and experience suggested efficacy of Lidocaine 5% plasters in children and adolescents with localised neuropathic pain. Initiated by the Pain in Children Special Interest Group (PICSIG) of the British Pain Society, a 3-year prospective multicentre service evaluation was undertaken to document the usage and efficacy of the Lidocaine 5% plaster in paediatric patients being managed by paediatric pain teams in the United Kingdom. Five paediatric pain teams provided anonymised data pre-treatment and 3-6 months after commencing Lidocaine 5% plaster. Changes in pain score, function, sleep and continuing use were evaluated. Data were obtained for 115 patients; age range 5-18 years (mean: 12 years). Diagnosis and site of application varied. Benefit from use of a Lidocaine 5% plaster in an individual was deemed if two or more of the following were reported: reduction in pain score, functional improvement, sleep improvement and continuing use of Lidocaine 5% plaster. Benefit was recorded for 79 patients (69%); 32 patients were recorded as receiving no benefit and data were unavailable for 4 patients, and 7 patients reported minor skin reactions. This prospective service evaluation supports the efficacy of the Lidocaine 5% plaster in children and adolescents with localised neuropathic pain and confirms tolerability and safety. It is the opinion of the PICSIG of the British Pain Society that the Lidocaine 5% plaster should be considered early in the multidisciplinary management of localised neuropathic pain in children and adolescents.
