Dupixent is a prescription medication approved by the Food and Drug Administration (FDA) to treat people age 12 and up with moderate to severe atopic dermatitis in cases where traditional therapies are not safe or effective. Dupixent may be referred to by its drug name, Dupilumab.

Dupixent is an immunomodulator, or drug that modulates the immune system. It is considered a biologic drug, and more specifically, an interleukin-4 (IL-4) receptor alpha antagonist. Dupixent is a genetically engineered molecule believed to work by blocking IL-4 and IL-13, chemical messengers involved in autoimmune attacks. Dupixent prevents IL-4 and IL-13 from signaling the immune system to attack the tissues.

How do I take it?
Dupixent is administered as a subcutaneous injection every other week after initial loading doses.

Dupixent is available as a prefilled single-use syringe.
