  • Close monitoring is essential when initiating fluoxetine treatment in adolescents, particularly during the first few months or when changing doses, as recommended by the American Academy of Pediatrics 1, 2
  • Monitor for emergence of adverse events including behavioral activation, agitation, and suicidal ideation, as advised by the American Academy of Pediatrics 2
  • Starting at higher doses may increase the risk of deliberate self-harm and/or suicide, as noted by the American Academy of Pediatrics 2

Clinical Evidence and Efficacy

Important Precautions

  • Fluoxetine should be slowly tapered when discontinued to limit withdrawal symptoms, as recommended by the American Academy of Pediatrics 2
  • Avoid abrupt discontinuation; taper the medication gradually, as advised by the American Academy of Pediatrics 2
  • Avoid concurrent use with MAOIs, as recommended by the American Academy of Pediatrics 1, 2
