The common off-label uses:Anxiety Disorders: Gabapentin is sometimes used to manage generalized anxiety disorder (GAD) and social anxiety, especially in patients who don’t respond well to traditional anti-anxiety medications.Bipolar Disorder: While not a first-line treatment, gabapentin may be used as an adjunct to stabilize mood in patients with bipolar disorder, particularly those who have difficulty tolerating other mood stabilizers. Long ago, there was a consensus in psychiatry that all anticonvulsants had antimanic effects. In 2000, gabapentin became the first anticonvulsant to challenge that idea, with a negative trial in bipolar mania that was followed by similar disappointments from topiramate and oxcarbazepine (Pande AC et al, Bipolar Disord 2000;2(3 Pt 2):249–255). Gabapentin is not reliable on its own in bipolar disorder, but two placebo-controlled trials suggest it may have a role as adjunctive therapy. It augmented lithium in acute mania and had mild preventive effects over a year when added to various mood stabilizers. As encouraging as these results are, both came from small trials with a total n of 85 (Astaneh AN and Rezaei O, Int J Psychiatry Med 2012;43(3):261–271; Vieta E et al, J Clin Psychiatry 2006;67(3):473–477). In practice, gabapentin is best reserved for treating bipolar disorder in patients with comorbidities like anxiety and alcohol or cannabis use disorders.Insomnia: Due to its sedative effects, gabapentin is occasionally prescribed to help with sleep disorders, especially for those who struggle with sleep due to chronic pain or anxiety.Alcohol Dependence and Withdrawal: Gabapentin is used to help reduce cravings and manage withdrawal symptoms in patients with alcohol use disorder, as it can help alleviate anxiety, tremors, and insomnia associated with withdrawal.Migraine Prevention: Gabapentin is sometimes used off-label to prevent migraines, especially in cases where traditional migraine medications are ineffective or not tolerated.Hot Flashes: Particularly for postmenopausal women or breast cancer patients, gabapentin can be prescribed to help reduce the frequency and intensity of hot flashes.Restless Legs Syndrome (RLS): Gabapentin can help alleviate symptoms of RLS, a condition that causes uncomfortable sensations and an urge to move the legs.Gabapentin has only three FDA indications: partial seizures, post-herpetic neuralgia, and restless legs syndrome (RLS).
