Intralesional Betamethasone as a Therapeutic Option for Alopecia Areata

The article discussed the use of intralesional betamethasone as an alternative treatment for alopecia areata (AA), an inflammatory hair loss condition with autoimmune and genetic components. Intralesional corticosteroids, particularly triamcinolone acetonide, were traditionally used, but due to supply issues in Brazil, betamethasone was proposed as a viable substitute. Betamethasone, available in two formulations, was noted for its high anti-inflammatory potential, low cost, and ease of access. The authors suggested that betamethasone could be a good alternative to triamcinolone for intralesional treatment of AA, given its efficacy and formal dermatological indication.
