Gabapentin (Neurontin) is a pharmaceutical drug, specifically a GABA analog. It was originally developed to treat epilepsy, and currently is 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.
It is also commonly prescribed by doctors for many off-label treatments, such as restless leg syndrome, insomnia, and bipolar disorder. There are, however, concerns regarding the quality of the trials conducted for a number of conditions.
Gabapentin is used primarily to treat seizures, neuropathic pain, including concussions, and hot flashes. There are, however, concerns regarding the quality of the research on its use to treat migraines, bipolar disorders, and pain.
