Gabapentin is an anticonvulsant medication used to control seizures in people with epilepsy. It’s also used to treat restless legs syndrome and relieve nerve pain in conditions like postherpetic neuralgia, a chronic pain condition in people who have had shingles.It’s not completely clear how gabapentin works, but it seems to reduce unusual excitement in the brain for people with seizures and helps in pain management by changing how the body senses pain.
