Bullous pemphigoid is an autoimmune disorder characterized by the development of tense blisters on various areas of the body. Dupilumab (Dupixent) is a monoclonal antibody used initially in the management of atopic dermatitis, a type of eczema. Dupixent works on IL-4 and IL-31 receptors, effectively blocking them and this is how it helps control atopic dermatitis.

A recent multicenter trial demonstrated that 92.3% of patients treated with Dupixent achieved complete clearance or satisfactory response with no adverse effects. Typically, we have used either oral steroids or oral methotrexate, which are potent immunosuppressants, to control moderate to severe cases of bullous pemphigoid.

Dupixent may be a useful additional tool for the management of bullous pemphigoid.
