Background: Little is known regarding differential effects of systemic anti-acne treatments on mental health.
Objective: To determine whether differences exist in mental health outcomes between acne patients treated with isotretinoin versus oral antibiotics (doxycycline, minocycline, or tetracycline).
Methods: Population study utilizing the 2004-2017 Medical Expenditure Panel Survey. Depressive symptoms were assessed using Patient Health Questionnaire 2 (PHQ-2); psychological distress was measured by the Kessler 6-Item Psychological Distress Scale (K6). Acne patients completed both the PHQ-2 and K6 during treatment with isotretinoin or oral antibiotics. Lower scores on both measures indicate better mental health outcomes.
Results: After adjusting for socio-demographic characteristics, patients on isotretinoin had fewer depressive symptoms than patients on oral antibiotics, as measured by mean PHQ-2 scores (isotretinoin 0.280 vs oral antibiotics 0.656, difference=0.337, P<0.01). The adjusted comparison also showed patients on isotretinoin had less psychological distress than patients on oral antibiotics, as measured by K6 scores (isotretinoin 2.494 vs oral antibiotics 3.433, difference=0.759, P=0.043).
Limitations: No direct assessment of acne severity.
Conclusion: Acne patients on isotretinoin experienced less depressive symptoms and psychological distress as compared to oral antibiotics. J Drugs Dermatol. 2021;20(2):172-177. doi:10.36849/JDD.5559.
