Gabapentin, also known by the brand name Neurontin, is a prescription Painkiller belonging to its own drug class, Gabapentinoids. It is considered an anticonvulsant, and is most commonly used to treat epilepsy, restless leg syndrome, hot flashes, and neuropathic pain. It is often used as a less addictive alternative to Opioids; however, Gabapentin addiction and abuse still occur in many patients.
