What is Gabapentin?
Gabapentin is a prescription medicine originally developed to treat seizures (epilepsy). Over time, doctors discovered it also works well for nerve pain and certain other conditions.
It belongs to a class of drugs called anticonvulsants. Gabapentin changes the way the brain and nerves send signals, which helps in reducing seizures and pain caused by nerve damage.
👉 It is available under brand names like Neurontin, Gralise, and Horizan.
