Atomoxetine Does NOT Typically Cause Acne or Skin Breakouts
Acne and skin breakouts are not recognized as common or documented adverse effects of atomoxetine (Strattera) based on FDA labeling and clinical guidelines. The most common adverse effects in children and adolescents are gastrointestinal (nausea, vomiting, abdominal pain), decreased appetite, fatigue, mood swings, and somnolence 1.
What the FDA Label Actually Reports
The official FDA prescribing information for Strattera lists "rash" occurring in only 2% of pediatric patients—the same rate as placebo 2. This is not acne or breakouts, but rather a general skin reaction. Acne is not mentioned anywhere in the comprehensive adverse event profile from clinical trials involving over 5,000 children 2.
Documented Skin-Related Effects (Not Acne)
The evidence shows atomoxetine can cause other skin phenomena, but these are distinct from acne:
Skin picking behavior: Two contradictory case reports exist—one showing atomoxetine caused skin picking 3, another showing it treated skin picking 4. This represents excoriation (self-inflicted skin damage), not acne.
Vitiligo: One case report documented depigmentation possibly related to atomoxetine's effects on the noradrenergic system 5. This is loss of skin color, not breakouts.
Rash: Occurs at the same 2% rate as placebo, suggesting no true causal relationship 2.
Why This Matters Clinically
If a patient on atomoxetine develops acne or breakouts, look for alternative explanations:
- Age-related acne: Most atomoxetine users are adolescents, the peak age for acne vulgaris independent of medication
- Other medications: Corticosteroids, anabolic steroids, testosterone, lithium, and certain anticancer agents have established causal relationships with drug-induced acne 6
- Coincidental timing: Acne onset may simply coincide with medication initiation
Common Pitfalls to Avoid
Do not discontinue atomoxetine based on acne concerns without considering that:
- The temporal association may be coincidental
- Standard acne treatments (topical benzoyl peroxide, retinoids, or combination therapy) should be first-line 7, 8, 9
- Atomoxetine provides important benefits for ADHD management that should not be abandoned without clear causation
The evidence strongly suggests atomoxetine does not cause acne. If breakouts occur during treatment, manage them as you would typical acne vulgaris rather than attributing them to the medication.
