Bupropion (Wellbutrin) and Trichotillomania: No Direct Association with Worsening
There is no established evidence that bupropion (Wellbutrin) worsens trichotillomania; in fact, limited case reports suggest it may potentially help treat the condition when SSRIs fail.
Evidence Assessment
FDA Drug Label Warnings
The FDA-approved prescribing information for Wellbutrin does not list trichotillomania or hair-pulling behaviors as adverse effects 1. The primary neuropsychiatric warnings focus on:
- Depression and suicidal ideation/behavior (particularly in smoking cessation contexts) 1
- Mood changes including mania, psychosis, hallucinations, and aggression 1
- Seizure risk (dose-dependent, approximately 0.1% at standard doses) 1
Notably absent from these extensive safety warnings is any mention of trichotillomania or compulsive hair-pulling behaviors.
Clinical Evidence Supporting Potential Benefit
The available research, though limited, actually suggests bupropion may be therapeutic rather than harmful for trichotillomania:
Case report evidence: A 23-year-old woman with fluoxetine-resistant trichotillomania showed clinically significant improvement when treated with sustained-release bupropion (up to 450 mg/day) plus cognitive behavioral therapy, with sustained improvement over 12 months 2
Mechanistic rationale: Trichotillomania involves multiple neurotransmitter pathways beyond serotonin, including the mesolimbic dopaminergic system. Bupropion's dopamine and norepinephrine reuptake inhibition may address these alternative pathways when SSRIs fail 2
Additional case support: Bupropion combined with naltrexone has been reported to successfully manage trichotillomania alongside depression in a patient with polycystic ovary syndrome 3
Current Treatment Landscape
Recent comprehensive reviews of trichotillomania pharmacotherapy 4, 5, 6, 7 consistently identify:
- No FDA-approved medications for trichotillomania treatment 4, 5
- First-line evidence supports N-acetylcysteine, clomipramine, and olanzapine 5, 7
- Bupropion is not mentioned as causing or worsening trichotillomania in systematic reviews of treatment options 5, 6, 7
Clinical Implications
When to Consider Bupropion
- Patients with trichotillomania who have failed SSRI trials 2
- Comorbid depression requiring treatment 3
- Smoking cessation needs (though monitor neuropsychiatric symptoms closely) 8
Monitoring Recommendations
While bupropion doesn't worsen trichotillomania, monitor for:
- Neuropsychiatric changes: Agitation, mood changes, suicidal ideation (particularly in first weeks of treatment) 8, 1
- Seizure risk factors: Avoid in patients with eating disorders (anorexia/bulimia), brain metastases, or abrupt alcohol/benzodiazepine discontinuation 8, 1
- Blood pressure: Check baseline and monitor periodically, especially if combined with nicotine replacement 1
Important Caveats
- The evidence for bupropion treating trichotillomania is limited to case reports; controlled trials are lacking 2, 5
- Treatment decisions should account for comorbidities, particularly depression where bupropion has established efficacy 8
- Cognitive behavioral therapy remains the primary evidence-based treatment for trichotillomania and should be combined with any pharmacotherapy 2, 7
