Neurontin vs Gabapentin: are they the same?
Neurontin is a commercial brand whose active ingredient is exactly Gabapentin. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Neurontin contains Gabapentin as its active ingredient. Talking about "Neurontin" in clinical terms is the same as talking about Gabapentin at the dose strengths 100mg, 300mg, 400mg, 600mg, 800mg. The differences from the authorised generic are brand, manufacturer (Pfizer), excipients, tablet appearance and price — not the active molecule itself.
When Neurontin is used
Neurontin is approved in adults and children aged 3 years and older as adjunctive therapy for partial-onset seizures, and in adults for post-herpetic neuralgia.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: Gabapentin binds the alpha-2-delta auxiliary subunit of voltage-gated calcium channels in the central nervous system, reducing presynaptic calcium influx and the release of excitatory neurotransmitters such as glutamate…
Brand or generic — which to choose?
For most patients, authorised generics of Gabapentin are clinically equivalent substitutes for Neurontin and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.

Is generic Gabapentin as effective as Neurontin? ▾
Yes. Authorised generics of Gabapentin must demonstrate bioequivalence to the brand. The active substance is the same; average effect is the same. Price is usually substantially lower.
Why does Neurontin cost more than generic Gabapentin? ▾
The price difference reflects originator development costs, brand recognition and competition among generic manufacturers. The molecule is identical; the cost is not.
