"The use of antidepressants as the sole therapeutic intervention for AN is unsupported, and these agents should only be used as adjunctive treatment to nutritional restoration and psychotherapy. There is a general lack of evidence to support use of SSRIs or mirtazapine during the AN acute treatment phase in underweight individuals. As a result, clinicians should not use antidepressants during hospitalization while patients are undergoing initial weight and nutritional restoration. At this time, the data are inconclusive regarding the place of SSRIs and mirtazapine and for their benefits in individuals with AN during the maintenance treatment phase once the weight is at least partially restored. Health care professionals should use clinical judgment in recommending fluoxetine or possibly citalopram, sertraline, or mirtazapine as adjunctive treatment to psychotherapy for relapse prevention and/or improvement of symptoms of depression and anxiety and/or obsessive-compulsive behaviors that did not to resolve with nutritional rehabilitation and psychotherapy. A combination of psychotherapy and different pharmacologic modalities may be used under the rationale that the efficacy of these treatments might be additive or perhaps synergistic to increase treatment success in weight-restored anorexic patients."
