Treatment for OCD ideally involves a combination of cognitive-behavioural therapy and drug therapy. It is important that people with OCD receive treatment that is specific to OCD, from a fully qualified therapist. Some forms of traditional psychotherapy are not effective at relieving symptoms of OCD.
The dual serotonin-norepinephrine reuptake inhibitor antidepressants (SNRIs) venlafaxine (Effexor) and duloxetine (Cymbalta) may also have efficacy in OCD, and they have safety and tolerability profiles comparable to those of the SSRIs. However, neither has yet been FDA-approved specifically for treatment of OCD.
