Gabapentin, initially developed as an anticonvulsant medication, is widely utilized to manage neuropathic pain syndromes, including postherpetic neuralgia and diabetic peripheral neuropathy. Structurally resembling the neurotransmitter gamma aminobutyric acid, it modulates voltage gated calcium channels in the central nervous system, reducing the release of excitatory neurotransmitters. Patients frequently report somnolence, dizziness, or peripheral edema during the initial titration phase. Due to its central nervous system depressant effects, avoiding alcohol and other sedating medications is highly recommended to prevent profound drowsiness. Discontinuation must follow a gradual taper schedule managed by a healthcare provider to avoid withdrawal symptoms.
