Everything You Need to Know About Gabapentin (Neurontin)
Gabapentin, commonly known by its brand name Neurontin, is a medication often prescribed for nerve pain, seizures, and certain anxiety disorders. If you’re considering gabapentin or just want to learn more about it, this guide breaks it down in simple, easy-to-understand terms.
What is Gabapentin?
Gabapentin is a medication that was originally developed to treat seizures but is now widely used for nerve pain and anxiety. It works by calming overactive nerves in your brain and body. Although it’s structurally similar to a brain chemical called GABA, it doesn’t directly affect GABA. Instead, it binds to a specific part of nerve cells (the α2-δ subunit of calcium channels) to reduce the release of certain neurotransmitters. This helps to decrease pain signals, prevent seizures, and calm anxiety.

- Partial seizures (as an add-on treatment for epilepsy).

It’s also prescribed off-label for:
- Neuropathic pain (nerve pain from diabetes or other conditions).
