Psychiatric Uses of Gabapentin.

Objective: This article reviews evidence-based psychiatric uses of gabapentin, along with associated risks.

Method of research: An extensive literature review was conducted, primarily of articles searchable in PubMed, relating to psychiatric uses, safety, and adverse effects of gabapentin.

Results: Evidence supports gabapentin as a treatment for alcohol withdrawal and alcohol use disorder. There is sufficient evidence to consider gabapentin as a third-line treatment for social anxiety disorder and severe panic disorder. Evidence does not support the use of gabapentin for bipolar disorder, major depressive disorder (MDD), posttraumatic stress disorder (PTSD), obsessive compulsive disorder (OCD), stimulant use disorder, or opioid withdrawal. Risks of gabapentin use are highest among those with a history of a substance use disorder and those concurrently taking opioids.

Conclusion: While gabapentin has a place in psychiatry for a select few indications, the literature does not support its use for many studied diagnoses.
