Non-Submental Applications of Injectable Deoxycholic Acid: A Systematic Review.

Introduction: Injectable deoxycholic acid (DCA; Kybella; Allergan, Irvine, CA) is currently approved only for treatment of persistent submental fat (SMF). Many cosmetic surgeons use DCA off-label to treat fat tissue in other areas of the body. There is no review summarizing the off-label uses of injectable DCA. Methods: A systematic literature search was conducted through PubMed, Cochrane, CINAHL, and Web of Science databases using search terms “ATX-101 OR Kybella OR deoxycholic OR deoxycholate NOT amphotericin NOT bile” in accordance to PRISMA guidelines to identify off-label uses for injectable DCA or ATX-101. Results: Ten pertinent articles were identified for review. Anatomic areas treated include the face, brassiere line, foot, and gluteotrochanteric region. Indications include facial contouring, paradoxical adipose hyperplasia, HIV/HAART-associated buccal fat pad lipodystrophy, and reduction of lipomatous tumors. DCA is efficacious at causing lipolysis and safe with minimal side effects. Most patients treated for cosmetic indications reported high patient satisfaction. Conclusion: Off-label use of injectable DCA demonstrate a similar safety profile, effectiveness, and overall patient satisfaction compared to FDA-approved use for persistent SMF. DCA appears to be a safe and efficacious alternative to surgical reduction of unwanted adipose tissue in non-submental areas. Larger-scale studies are warranted to explore further cosmetic and potential medical applications. J Drugs Dermatol. 2019;18(7):675-680.
