Overview
Gabapentin, marketed as Neurontin, is an anticonvulsant and neuropathic-pain agent first approved in 1993. Structurally related to GABA but not acting directly on its receptors, it modulates calcium-channel activity in neurons, decreasing excitatory neurotransmitter release.
Uses
Indicated for partial seizures, postherpetic neuralgia, and neuropathic pain. Off-label uses include restless-legs syndrome, fibromyalgia, and anxiety.Dosage & Administration
Initial dose: 300 mg once on day 1, then 300 mg twice on day 2, and 300 mg three times daily thereafter. Maintenance ranges 900–1800 mg/day in divided doses. Adjust for renal impairment. Capsules should be swallowed whole with water.Side Effects & Warnings
Common: dizziness, somnolence, ataxia, and peripheral edema. Serious but uncommon: mood changes, suicidal ideation, and respiratory depression when combined with opioids. Abrupt cessation may precipitate seizures.Patient Considerations
Take consistently; do not double doses. Avoid driving until effects are known. Report swelling or mood alterations.Ready for next steps?
