Background: The association between exposure to Isotretinoin, the development of depression and suicide attempts is controversial.
Objective: To retrospectively assess pattern of utilization of mental health services in the Israeli Defense Forces (IDF) during a 5-year period for all subjects exposed to Isotretinoin in comparison to a control group consisting of army conscripts suffering from psoriasis. All subjects were young adults (18 to 21 years old) in compulsory military service.
Method: Exposure to Isotretinoin mandates reporting and marking as a coded medical profile in the IDFs' computerized medical record of each conscript and soldier. Medical data, tracked by military medical profiles, were summarized from medical records of all subjects treated by Isotretinion during the years 1999-2003 and for the control group for the same period. Use of mental health services was the a-priori defined primary outcome measure.
Results: During the study period 1419 subjects were exposed to Isotretinoin and 1102 suffered from psoriasis. Utilization of mental health services was highest for the index group wherein 17.2% (245/1419) of subjects were evaluated or treated compared to 12.5% in the control group (psoriasis). The inter-group differences were statistically significant; Chi-square=15.9 (df=2), p=0.0003.
Conclusions: We suggest that psychiatric evaluation be regularly undertaken prior to initiation of Isotretinion treatment in young adults at risk, as well as providing follow-up visits during and at completion of treatment.
