Gabapentin is used alone or in combination with other medications to treat seizures caused by epilepsy in adults and children who are at least 12 years old. Gabapentin is also used with other medications to treat partial seizures in children who are 3 to 12 years old.

Gabapentin is also used in adults to treat nerve pain caused by herpes virus or shingles (herpes zoster), and to treat restless legs syndrome (RLS).
