Infobord.png More information
  • Fluoxetine and its metababolite desmethyl-fluoxetine have a very long elimination time of about 1 week; phasing out fluoxetine is therefore not necessary.
  • Fluoxetine slows the metabolism of trazodone via CYP2D6, so caution is necessary for at least four weeks.
  • Occurrence of the serotonin syndrome is not likely, but theoretically possible, so caution is necessary.
  • Safe target dose of trazodon as antidepressant = 150 mg
  1. Switches are based on literature references on this page and expert opinions of the authors. The authors have used pharmacokinetic and receptor affinity properties to determine the switch schedules
