Gabapentin is a prescription medication primarily used to treat nerve pain and prevent seizures. It works by calming overactive nerve signals in the brain. While not a controlled substance at the federal level in the U.S., it carries risks of misuse, dependence, and side effects like dizziness and drowsiness. It must be used under medical supervision, especially as misuse is a growing concern. It is not suitable for everyone and requires a doctor's prescription.
