Infobord.png More information
  • No wash-out period is needed.
  • Bupropion slows the metabolism of paroxetine by CYP2D6.
  • Bupropion and its metabolites have long elimination times, so plasma concentrations will reduce gradually.
  • The interaction by CYP2D6-inhibition is not relevant because of low dosages during the switch.
