Looking to buy Gabapentin legally and easily for epilepsy? Gabapentin is a prescription medication primarily used to treat seizures associated with epilepsy. It belongs to a class of drugs known as anticonvulsants or antiepileptic drugs, which work by calming overactive nerve activity in the brain that can lead to seizures. In addition to epilepsy, Gabapentin is also prescribed to manage nerve pain caused by conditions such as postherpetic neuralgia and diabetic neuropathy.
