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.
  • Occurrence of the serotonin syndrome is not likely, but theoretically possible, so caution is necessary.
  • Fluoxetine inhibits CYP2C19, CYP2D6 and CYP3A4, which metabolize escitalopram.
