In a double-blind, placebo-controlled trial of clonazepam in the treatment of neuroleptic-induced akathisia in older adolescents, clonazepam was significantly more effective at reducing akathisia scores at the end of the first treatment week than placebo (p less than 0.0001). Clonazepam may be a safe and effective treatment for neuroleptic-induced akathisia in this age group.
