This needs clarification, OCD is classified as GAD and its treatment is in most cases SSRI used in combination or alone to CBT, on the other hand, when anxiety doesn't appear to have sign of obsessive or compulsive behavior anxiolytic agents are tried, but due to the dependence and the need to increase the dosage, CBT is favoured. But those are not the only treatment, in some cases, when in cases of severe social-phobia, uncontrolable depersonalization/derealization and the patient doesn't respond, atypical anti-psychotics at lower dosage might be tried. Anxiety treatment depending on the severity or the type is a case by case matter, but when taken 'anxiety alone' it is generally known that meanstream treatment includes anxiolytic agents and/or CBT.
