Dupilumab for Allergic Contact Dermatitis: An Overview of Its Use and Impact on Patch Testing

Abstract

Allergic contact dermatitis (ACD) has been estimated to affect up to 20% of the general population. Patch testing is the gold standard for identification of causative allergens. When allergen avoidance fails, current treatment options include topical and oral corticosteroids, systemic immunosuppressants, and phototherapy. Dupilumab, a monoclonal antibody targeting IL-4/IL-13, is approved by the US Food and Drug Administration for the treatment of moderate to severe atopic dermatitis. It also has been used off label with some success in the treatment of ACD. This article discusses the evidence for using dupilumab to treat ACD as well as considerations for patch testing in patients who are taking this medication.
