Gabapentin is a prescription drug used to treat partial seizures, postherpetic neuralgia, and neuropathic pain associated with diabetic peripheral neuropathy. It may also be used to prevent certain types of migraine headaches. Gabapentin belongs to a class of drugs known as anticonvulsants. It works by decreasing abnormal excitement in the brain caused by misfiring nerves.
Do not take gabapentin if you have taken a monoamine oxidase inhibitor (MAOI) such as isocarboxaz.
