I'd be grateful if anyone could direct me to evidence-based guidelines/recommendations on managing anxiety/depression in patients with SSRI sensitivity, i.e., patients who have difficulty tolerating SSRI's because of problematic side-effect that appear suggestive of serotonin syndrome, and other antidepressants including mirtazapine and venlafaxine appear to cause similar difficulties? Would buspirone or quetiapine be appropriate in such situations?
