Nervigesic 150 mg (pregabalin) is a prescription medication used to manage neuropathic pain—from diabetes, shingles, or spinal cord injury—alongside fibromyalgia, anxiety, and as adjunctive therapy for partial-onset seizures. It works by calming overactive nerve signals. Benefits often appear within a week, though drowsiness, dizziness, dry mouth, blurred vision, weight gain, or swelling may occur. Use only under medical supervision.
