Action: How Dupixent works

Dupixent is an injectable prescription medicine that inhibits IL-4 and IL-13 proteins by blocking a shared receptor. IL-4 and IL-13 play a major role in the symptoms of atopic dermatitis.

Dupixent belongs to a class of medicines called monoclonal antibodies. Monoclonal antibodies are proteins that specifically recognise and bind to other unique proteins in the body.

The active ingredient in Dupixent is dupilumab 300 mg.

It also contains the inactive ingredients acetic acid, arginine hydrochloride, histidine, polysorbate 80, sodium acetate, sucrose, and water for injections.
