What is Gabapentin?
Gabapentin (brand name: Neurontin) is a prescription anticonvulsant and neuropathic pain medication used to treat nerve pain caused by shingles (post-herpetic neuralgia) and as add-on therapy for partial-onset seizures. It is also very widely used off-label for diabetic neuropathy, restless legs syndrome (RLS), fibromyalgia, chronic pain, alcohol withdrawal, and anxiety. Gabapentin works by binding to alpha-2-delta subunits of voltage-gated calcium channels in the nervous system, reducing the release of excitatory neurotransmitters that cause nerve pain and seizures. Doses range widely from 300 mg to 3,600 mg per day in divided doses. A licensed provider can prescribe gabapentin through Rx.com for nerve pain or seizure conditions. Generic gabapentin is very affordable with an Rx.com coupon.Side Effects

What Is Gabapentin (Neurontin)?
Gabapentin (brand name Neurontin) is a prescription anticonvulsant and nerve pain medication with FDA approvals for post-herpetic neuralgia and adjunctive therapy for partial seizures. It is one of the most widely prescribed drugs in the US, with extensive off-label use for a broad range of pain and psychiatric conditions.
FDA-Approved Uses
- Post-herpetic neuralgia (PHN) — nerve pain after a shingles (herpes zoster) outbreak
- Partial-onset seizures — adjunctive (add-on) therapy in adults and children ≥3 years
Common Off-Label Uses
- Diabetic peripheral neuropathy — burning, tingling, shooting pain in feet and legs
- Restless legs syndrome (RLS)
- Fibromyalgia — widespread pain reduction
- Chronic pain syndromes — including back pain and complex regional pain syndrome
- Alcohol and substance withdrawal
- Anxiety disorders — off-label anxiolytic
- Insomnia
How Does Gabapentin Work?
Despite its name, gabapentin does not directly affect GABA receptors. It binds to the alpha-2-delta (a2d) subunit of voltage-sensitive calcium channels in the brain and spinal cord. This reduces calcium influx in hyperexcited neurons, decreasing the release of excitatory neurotransmitters (glutamate, substance P, CGRP) that drive nerve pain and seizures.
Dosage Overview
- PHN: Start 300 mg on Day 1, 300 mg twice on Day 2, 300 mg three times on Day 3; titrate up to 1,800 mg/day (max 3,600 mg/day)
- Seizures (adjunctive): 300 mg three times daily; titrate to 1,800–3,600 mg/day
- Diabetic neuropathy (off-label): 300–1,200 mg three times daily
Reduce dose in patients with kidney impairment. Do not stop abruptly — gradual taper reduces withdrawal risk.
Side Effects
Common: dizziness, somnolence (drowsiness), coordination problems (ataxia), fatigue, and peripheral edema. Side effects are often dose-dependent and may decrease over time.
