What Is Dupixent?
Discover how Dupixent helps manage moderate-to-severe eczema in the U.S. Learn about its effectiveness, and how it compares to traditional treatments.
Dupixent (dupilumab) is a prescription biologic therapy approved to treat moderate-to-severe atopic dermatitis (eczema) in adults and children as young as 6 months. Unlike topical treatments, Dupixent works from the inside out by targeting the immune response responsible for chronic inflammation.
It has become a leading option for patients who:
-
Experience frequent eczema flare-ups
-
Have not responded to topical corticosteroids or immunomodulators
-
Need long-term, steroid-free management
How Dupixent Works
Dupixent blocks interleukin-4 (IL-4) and interleukin-13 (IL-13)—two key proteins that cause inflammation in atopic dermatitis. By inhibiting these pathways, it helps:
-
Reduce itching and skin redness
-
Prevent new eczema patches
-
Improve skin barrier function over time
Patients typically self-administer Dupixent via injection every two weeks, following an initial loading dose.
