  • Fluoxetine and its metababolite desmethyl-fluoxetine have a very long elimination time of about 1 week; phasing out fluoxetine is therefore not necessary.
  • Occurrence of the serotonin syndrome is not likely, but theoretically possible, so caution is necessary.
  • Safe target dose escitalopram = 10 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
