For some patients, gabapentin effectively treats diabetic neuropathy, or nerve pain, according to MedicineNet. This condition often occurs in people with diabetes. The level of severity and body part affected varies among patients.
Gabapentin was originally developed as anti-seizure medication for epilepsy, but doctors have expanded its use, Mayo Clinic explains. In addition to helping patients with diabetes, the drug is also prescribed to relieve nerve pain in adults who have had shingles.
The most common side effects of gabapentin are clumsiness and uncontrollable eve movement, states Mayo Clinic. Potentially serious side effects that need immediate medical attention include swallowing or breathing problems, seizures and swelling of the face or throat, MedlinePlus indicates.
