Gabapentin 1200 mg is considered a moderate to high daily dose of an anticonvulsant medication. It's primarily used to manage nerve pain (neuropathy) and partial seizures, but it can also be prescribed off-label for issues like anxiety or restless leg syndrome. Typically, this dosage is split into two or three smaller doses throughout the day like taking 600 mg twice a day or 400 mg three times a day to help keep consistent levels in the bloodstream and improve symptom management.
