Gabapentin Original Indications: Anticonvulsant and Neuropathic Pain Treatment
Antiseizure Drug Development and Epilepsy Indication
Gabapentin was originally developed as an anticonvulsant medication, specifically designed to treat epilepsy. Its initial clinical use focused on managing refractory partial seizures and secondarily generalized tonic-clonic seizures in humans, as it acts as a structural analogue of the neurotransmitter GABA and can cross the blood-brain barrier to exert its effects Di Cesare2023Smith2015. The U.S. Food and Drug Administration (FDA) approved gabapentin for use as an adjunctive therapy in the treatment of partial-onset seizures Goodman2019Campbell2021Smith2015.
FDA-Approved Pain-Related Indication: Postherpetic Neuralgia
In addition to its role in seizure control, gabapentin received FDA approval for the treatment of postherpetic neuralgia, a type of chronic neuropathic pain that occurs after shingles (herpes zoster) infection Goodman2019Campbell2021Smith2015. This remains the only pain-related indication for gabapentin that is officially approved by the FDA .
Summary of Original Indications
To summarize, gabapentin’s original, FDA-approved indications are:

- Management of postherpetic neuralgia (neuropathic pain following shingles) Goodman2019Campbell2021Smith2015
Conclusion
Gabapentin was initially developed and approved for use as an anticonvulsant to treat partial seizures and for the management of postherpetic neuralgia. While it is now widely prescribed for many off-label uses, these two conditions—epilepsy (partial seizures) and postherpetic neuralgia—remain its original, FDA-approved indications Goodman2019Di Cesare2023Campbell2021+1 MORE.
