Which antidepressants are FDA-approved for bulimia and trichotillomania? (ChatGPT, 2025-8-25)

 Great question — let’s split it by condition:





Bulimia Nervosa



  • FDA-approved antidepressant:
    • Fluoxetine (Prozac)
      • In 1994, the FDA approved fluoxetine for the treatment of bulimia nervosa.
      • Effective dose: 60 mg/day (higher than the typical 20 mg/day used for depression).
      • Evidence: RCTs showed fluoxetine reduced binge-eating and purging frequency, improved mood, and supported remission.
  • Other antidepressants:
    • Sertraline, citalopram, venlafaxine, etc. have shown some benefit in studies, but none are FDA-approved for bulimia.






Trichotillomania (Hair-Pulling Disorder)



  • FDA-approved antidepressants:
    • None.
  • What has been studied:
    • SSRIs (fluoxetine, sertraline, escitalopram) — mixed or weak results.
    • Clomipramine (a tricyclic antidepressant with strong serotonergic effects) showed some efficacy in early small studies, but it is not FDA-approved for trichotillomania.
    • Current guidelines consider medications off-label, with behavioral therapy (habit reversal training, CBT) as the first-line treatment.






✅ Summary



  • Bulimia nervosa: Fluoxetine (Prozac) is the only FDA-approved antidepressant.
  • Trichotillomania: No antidepressants FDA-approved (treatments are off-label; psychotherapy is first-line).





Would you like me to also give you a table of off-label pharmacologic options for trichotillomania (SSRIs, clomipramine, NAC, olanzapine, etc.), with evidence levels, so you can see what’s actually tried in practice despite lack of FDA approval?
