Treatment Patterns for Alopecia Areata in the US

This cohort study analyzed treatment patterns for alopecia areata (AA) in 45,483 adults in the US from 2015 to 2020, using medical and pharmacy claims data. The study found that corticosteroids, including intralesional, topical, intramuscular, and oral forms, were the most common treatments. Initially, nearly half of the patients did not receive treatment, and by 12 months post-diagnosis, almost 72% were not receiving any treatment. The study highlights a significant gap in ongoing treatment for AA and suggests the need for further research to understand why many patients discontinue treatment.
