The relief of depressive symptoms may appear earlier, about 2-4 weeks or 6-8 weeks will have obvious effects; the relief of obsessive-compulsive symptoms often need to be 6 weeks or even 12 weeks later, so it is important to adhere to the use of drugs. Psychotherapy for patients with obsessive-compulsive disorder is also very important, cognitive behavioral therapy, psychoanalysis and so on can be used, often with unexpected results. Because patients with obsessive-compulsive disorder and depression have repressed emotions, psychotherapy allows patients to express and vent bad emotions, and then to find repressed and hidden bad emotions and contradictions and conflicts, etc., for symptomatic relief is a very obvious effect, sometimes faster than medication to play a therapeutic role.
