“…The Institute of Medicine (2008) report goes so far as to assert there is insufficient evidence for the efficacy of pharmacotherapy, though it should be noted that this report did not definitively conclude that medications were ineffective for PTSD. Some national guidelines recommend SSRI medication or psychotherapy as first line treatments (Baldwin et al, 2005;Swinson et al, 2006;Ursano et al, 2004;Benedek et al, 2009) whereas others recommend relegating medications to second line treatments to be used only if psychotherapy fails or is unavailable (Forbes et al, 2007;National Collaborating Centre for Mental Health, 2005). Actual treatment choices in clinical practice are influenced by other factors, including treatment availability, patient preference, and the presence of significant comorbid disorders, such as depression, bipolar disorder, or other anxiety disorders (Rakofsky & Dunlop, 2011).…”
