Gabapentin and Klonopin (clonazepam) differ in class and use. Gabapentin is an anticonvulsant used for nerve pain and seizures, while Klonopin is a benzodiazepine for anxiety and seizures. Gabapentin has lower abuse potential and milder sedation. Klonopin works faster, with stronger calming effects but higher dependence risk. Gabapentin is taken more frequently; Klonopin’s longer half-life allows less frequent dosing and steadier symptom control.
