Policies to mitigate nonmedical use of prescription medications: how should emerging evidence of gabapentin misuse be addressed?

Over the past decade, increased prescription supply has facilitated an epidemic of nonmedical use of controlled substances, including predominantly opioids, as well as benzodiazepines, z-hypnotics, and stimulants. Areas covered: More recently, misuse of noncontrolled prescriptions, such as gabapentin, has been detected. Gabapentin misuse has been associated with drug-related harm and increased healthcare service utilization in a few studies, including a recent large-sample analysis of commercially insured enrollees in the United States (U.S.) Responding to this emerging base of evidence, a small number of U.S. states have acted to prevent or detect gabapentin misuse by requiring the inclusion of gabapentin utilization in reporting to local Prescription Drug Monitoring Programs (PDMPs) and/or imposing other restrictions on gabapentin prescribing (e.g., classification as a controlled substance, quantity limits). These efforts may result in unintentional harm by (1) encouraging 'doctor shopping' across state lines to seek lenient regulatory policies and (2) placing the burden for mitigating misuse on individual practitioners. Expert opinion: We call for a unified national approach, comprising federal regulation and enhanced PDMP reporting to address gabapentin misuse, while laying the groundwork for management of new medications of abuse that the healthcare industry may encounter in the future.
