Psychiatric disorders and suicidal behavior in patients with acne prescribed oral antibiotics versus isotretinoin: Analysis of a large commercial insurance claims database

Abstract

The association between isotretinoin and psychiatric disturbance, including depression and suicidal behavior, is controversial. To investigate whether acne patients prescribed isotretinoin or antibiotics were more likely to have psychiatric disorders and/or engage in suicidal behavior. Retrospective cohort study using the IBM MarketScan Research Databases, which contain commercial insurance claims in the United States, to identify acne patients who were prescribed isotretinoin or oral antibiotics between 2011 and 2017 and who were diagnosed with psychiatric disorders or suicidal behavior. A total of 72,555 patients were included in the study. Patients in the general population were 1.47 times more likely to be diagnosed with suicidal ideation or attempt compared to acne patients prescribed isotretinoin (adjusted odds ratio [OR] 1.47; confidence interval [95% CI], 1.27, 1.70; P<.0001). The general population (adjusted OR 0.87; 95% CI, 0.84, 0.89; P<.0001) and acne patients prescribed antibiotics (adjusted OR 0.88; 95% CI, 0.85, 0.91; P<.0001) were less likely to have a psychiatric diagnosis compared to acne patients prescribed isotretinoin. The prevalence of suicidal behavior during isotretinoin treatment was lower (0.10%; P=.082) than in the year prior to isotretinoin treatment (0.22%) and in the year following treatment (0.34%; P=.004). The study excluded individuals with public insurance and those who were uninsured, and the data in the study relied on the accuracy of the medical coding. Compared to the general population, acne patients prescribed isotretinoin were less likely to engage in suicidal behavior. Further exploration into the slight increase in suicidal behavior seen in isotretinoin patients 1year after therapy is warranted.
