Gabapentin - What is it for

Gabapentin is used to treat neuropathic pain (nerve pain) caused by damage to the nerves. The nerve damage may be due to conditions such as diabetes (diabetic neuropathy) or shingles (postherpetic neuralgia). Gabapentin works by reducing the amount of pain signals coming from damaged or abnormally functioning nerves.
