Oral isotretinoin in the treatment of juvenile acne and psychiatric adverse effects - a systematic review.

PURPOSE

Acne vulgaris is a very prevalent dermatological condition, especially among adolescents and young adults up to 25 years old, classifying it as juvenile acne. One of the most effective treatments for severe acne is isotretinoin, a derivative of retinoic acid. Despite its high efficacy, this drug has been linked to several side effects including psychiatric adverse alterations, such as anxiety, depression and even suicide. With this systematic review we aim to determine if it is possible to establish a causal relation between oral isotretinoin in the treatment of juvenile acne and the appearance of psychiatric adverse effects.

MATERIALS AND METHODS

We searched two distinct databases, PubMed and Web of Science, and considered the work published between January 2000 and November 2021.

RESULTS

Out of the 599 identified articles, we included 19 studies in this systematic review. Globally, the results we found do not support an association between the use of isotretinoin for acne treatment and mental side effects and the safety of this drug appears to be assured. However, the individual characteristics of each adolescent and their environment should be considered; the personal and family history of mental disorders are pointed out as red flags we should look out for when treating these patients.

CONCLUSION

Despite this being a highly debated topic, especially among the dermatology community, more studies with larger populations and randomised controlled trials are necessary to increase the strength of the evidence presented.
