title: Possible trazodone potentiation of fluoxetine: a case series.
abstract: BACKGROUND
  Fluoxetine is an effective serotonin reuptake inhibitor antidepressant that can fail to alleviate either insomnia or major depression in a substantial minority of depressed patients. Trazodone has been reported to be both an effective nonbenzodiazepine hypnotic for antidepressant-associated insomnia and a possible serotonergic antidepressant adjunct. We present a case series of patients with variable responses when trazodone was added to fluoxetine.
  
  
  METHODS
  Eight consecutive depressed (DSM-III-R) patients taking fluoxetine were given trazodone either for sleep or as a possible antidepressant potentiator.
  
  
  RESULTS
  Three (37.5%) of the eight patients (confidence interval = 4.0%-71.0%) had improvements in both sleep and depression. The remaining five patients either were unaffected by the addition of trazodone to fluoxetine or had intolerable adverse drug reactions.
  
  
  CONCLUSIONS
  Trazodone may be an effective hypnotic and antidepressant potentiator when combined with fluoxetine for some patients, but its use may be limited by adverse effects.
