Gabapentin 300 mg, or Neurontin, is an anti-seizure medication that is prescribed to prevent seizures in epileptic patients. In addition, gabapentin can be prescribed to treat nerve pain associated with nerve compression, shingles, and diabetic neuropathy. According to Drugs.com, researchers do not understand how gabapentin works to treat nerve pain. However, researchers do understand that gabapentin increased a natural chemical, known as GABA, in the brain. Increasing this chemical reduces the excitement of the nerves in the brain to prevent seizures. A patient taking gabapentin should be aware of the possible side effects and know what to do if they occur.
Gabapentin is available in 100-, 300-, and 400-mg capsules; in 600- and 800-mg tablets; and in a liquid solution containing 250 mg per 5 mL.
