Frequently Asked Questions
›What do I need to try before Dupixent?
Most insurers require failure of high-potency topical corticosteroids. Many also require trial of a systemic immunosuppressant (methotrexate, cyclosporine, or mycophenolate). For asthma, you'll typically need to fail ICS+LABA combinations.
›Does insurance cover Dupixent for eczema?
Yes, most plans cover Dupixent for moderate-to-severe atopic dermatitis — but with prior authorization. You'll need to document disease severity (BSA affected, impact on daily life) and prior treatment failures.
›How do I prove my eczema is severe enough for Dupixent?
Document body surface area (BSA) affected, IGA score, EASI score if available, and how eczema impacts your daily activities and sleep. Photos and dermatologist notes are critical for the appeal.
›Can I get Dupixent for asthma and eczema at the same time?
Yes, Dupixent treats both conditions. Your doctor should document both diagnoses in the PA request, as having multiple approved indications can strengthen the medical necessity argument.
