Gabapentin is a prescription medication used to treat nerve pain and certain anxiety disorders, often prescribed off-label for conditions like generalized anxiety or panic attacks. It works by stabilizing nerve activity, reducing pain, and calming overactive signals in the brain. While gabapentin is effective for nerve pain related to conditions like shingles or diabetic neuropathy, its use for anxiety may vary in effectiveness. Buying gabapentin online can be risky, as it is a controlled substance in many places and may be subject to scams or illegal sales. Always consult a healthcare provider before purchasing or using gabapentin for any condition.
