Obsessive–compulsive disorder
A form of psychotherapy called "cognitive behavioral therapy" (CBT) and psychotropic medications are first-line treatments for OCD. Other forms of psychotherapy, such as psychodynamic and psychoanalysis may help in managing some aspects of the disorder, but in 2007 the American Psychiatric Association (APA) noted a lack of controlled studies showing their effectiveness "in dealing with the core symptoms of OCD". The fact that many individuals do not seek treatment may be due in part to stigma associated with OCD.
Fluoxetine
The efficacy of fluoxetine in the treatment of obsessive–compulsive disorder (OCD) was demonstrated in two randomized multicenter phase III clinical trials. The pooled results of these trials demonstrated that 47% of completers treated with the highest dose were "much improved" or "very much improved" after 13 weeks of treatment, compared to 11% in the placebo arm of the trial. The American Academy of Child and Adolescent Psychiatry state that SSRIs, including fluoxetine, should be used as first-line therapy in children, along with cognitive behavioral therapy (CBT), for the treatment of moderate to severe OCD.
