What brand-name gabapentin products are there?
Gabapentin is sold under multiple brand names that can vary by country and formulation (for example, immediate-release capsules/tablets versus extended-release products). The most commonly recognized brand-name versions include:
- Neurontin (gabapentin immediate release)
- Gralise (gabapentin extended release)
- Horizant (gabapentin enacarbil; used for certain conditions)
How do the main gabapentin brands differ (immediate-release vs extended-release)?
Brand differences usually come down to how the drug is released in the body and what dosing schedules they use.
- Neurontin is the classic immediate-release gabapentin product, typically taken multiple times per day depending on the indication.
- Gralise is extended-release gabapentin designed for once-daily dosing with meals for certain approved uses.
- Horizant uses a prodrug form (gabapentin enacarbil) and is formulated for specific approved dosing schedules.
Are generic gabapentin and these brands interchangeable?
In many cases, generic gabapentin can be substituted for a brand when it matches the same active ingredient and release type (for example, immediate-release to immediate-release). Substitution may not be appropriate if the brand uses a different formulation or delivery method (for example, extended-release products), because dosing and how the drug is absorbed can differ.
If you share the exact product name on your prescription (or your country), I can narrow it to the closest equivalent.
