According to the DSM-5 diagnostic criteria for substance-related disorders, the misuse rate was 81.9% in patients using pregabalin and 69.69% in patients using gabapentin. Information regarding patients’ pregabalin and gabapentin use and misuse is shown in Table 1 .

A growing body of evidence highlights the potential risks of overprescribing the medication. For the purpose of this review, symptoms of gabapentinoid dependence are defined in line with the International Classification of Diseases 11th Revision (ICD-11) criteria for substance dependence and the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) criteria for substance use disorder.27 We will consider symptoms Epidemiological and case report evidence suggests that the anti-epileptic and analgesic medication gabapentin is being misused internationally, with substance abuse populations at special risk for misuse/abuse. integrated alcohol abuse and dependence into a single dis- Mild symptoms can be treated with carbamazepine or gabapentin. Benzodiazepines are DSM-5 = Diagnostic and Statistical Manual of Melatonin and anticonvulsants, particularly carbamazepine, gabapentin, topiramate and possibly pregabalin, are also helpful for withdrawal by reversing kindling and improving comorbid psychiatric symptoms (Vissers, Knipschild & Crebolder, 2007; Bobes, Rubio, Terián, Cervera, López-Gómez & Vilardaga, 2012). For example, in a cohort of 503 adults reporting current, nonmedical use of diverted prescription opioids in Appalachian Kentucky (and not presently in substance abuse treatment; study details are described elsewhere []), 15% of participants identified using gabapentin specifically “to get high” in the past 6 months. Gabapentin abuse will often cause negative side effects to the user and in most cases requires help to overcome. Like most forms of addiction, a person with a gabapentin use disorder will be diagnosed by a licensed professional using these 11 criteria, outlined by the DSM-5: The following are the DSM-5 criteria for gabapentin addiction: Taking gabapentin in larger amounts or for longer than intended. Making repeated unsuccessful efforts to cut down or discontinue use. endorsed gabapentin abuse compared with 4% of those with-out an opioid use disorder. In another study [42], a questionnaire-based survey w as . carried out in six substance misuse clinics in Scotland. Gabapentin was primarily misused for recreational purposes, self-medication, or intentional self-harm and was misused alone or in combination with other substances, especially opioids, benzodiazepines, and/or alcohol. Individuals with histories of drug abuse were most often involved in its misuse. Analgesic abuse, nonpsychotropic; Nonpsychotropic analgesic abuse; ICD-10-CM F55.8 is grouped within Diagnostic Related Group(s) (MS-DRG v 42.0): 894 Alcohol, drug abuse or dependence, left ama; 895 Alcohol, drug abuse or dependence with rehabilitation therapy; 896 Alcohol, drug abuse or dependence without rehabilitation therapy with mcc Essential screening tools for gabapentin addiction include the DSM-5 criteria and the CAGE-AID questionnaire. These tools help assess the severity of addiction, identify patterns of misuse, and guide treatment planning. Gabapentin misuse occurred concomitantly with any opioid (44.9%), benzodiazepines (38.8%), alcohol (24.5%), and powder cocaine (24.5), among others. Over the past two decades, prescribing of gabapentinoids has more than tripled in the USA, 1 the UK 2 and Australia. 3 4 The gabapentinoid drugs—gabapentin and pregabalin—are primarily approved for the treatment of epilepsy and neuropathic pain conditions. 5 Pregabalin is also approved for the treatment of fibromyalgia in the USA and Canada In the most recent fifth edition of the DSM (DSM-5; Association 2013), the categorical distinctions are replaced with “substance use disorders” which describe a constellation of 11 criteria symptoms, with specifiers to indicate severity based on the number of symptoms present.

For example, it does away with separate "dependence" and "abuse" diagnoses and combines them into "substance use Despite their inherent abuse potential, gabapentinoids (gabapentin and pregabalin) may be safer than presumed and offer prescribers an effective opioid-alternative treatment for certain types of neuropathic pain.
