Gabapentin is a widely used medication for managing nerve pain, such as that from shingles or diabetic neuropathy, and for controlling seizures. It stabilizes nerve activity in the brain to reduce abnormal signaling. Gabapentin can also help relieve restless leg syndrome and chronic neuropathic discomfort. Though generally well-tolerated, dizziness and fatigue may occur. Consistent use as prescribed is key for best results and to avoid withdrawal effects.
