Neurontin (gabapentin) is an anti-epileptic medication, also called an anticonvulsant. Gabapentin affects chemicals and nerves in the body that are involved in the cause of seizures and some types of pain.
Neurontin is used in adults to treat nerve pain caused by herpes virus or shingles (herpes zoster). Neurontin is also used to treat seizures in adults and children who are at least 3 years old.
