Gabapentin (Neurontin) is an anticonvulsant and analgesic drug. It was originally developed to treat epilepsy, and is currently also used to relieve neuropathic pain. It is recommended as a first line agent for the treatment of neuropathic pain arising from diabetic neuropathy, post-herpetic neuralgia, and central neuropathic pain.
Gabapentin is also commonly prescribed for many off-label uses, such as treatment of restless leg syndrome, anxiety disorders, insomnia, and bipolar disorder. There are, however, concerns regarding the quality of the trials conducted and evidence for some such uses, especially in the case of its use as a mood stabilizer in bipolar disorder.
