General Overview and Therapeutic Indications
Gabapentin is a pharmaceutical compound primarily used to treat disorders caused by abnormal electrical activity in the brain and nervous system. It was first approved in 1993 and is now available globally as a widely prescribed generic medication.
Primary FDA-Approved Uses in 2026:
Postherpetic Neuralgia (PHN): Relieving the chronic, stabbing nerve pain that often follows a shingles infection.
Partial Seizures: Used as an "add-on" (adjunctive) therapy for adults and children with epilepsy to help control focal seizures.
Restless Legs Syndrome (RLS): Specifically the extended-release form (Gabapentin Enacarbil), used to treat the strong urge to move legs at night.
Common Off-Label Uses: Doctors frequently prescribe Gabapentin for conditions not officially on the label, such as diabetic neuropathy, hot flashes associated with menopause, chronic hiccups, and certain anxiety disorders.
