Learn more about how Dupixent treats the following conditions.

Dupixent may also be used for other conditions as determined by your healthcare provider.

How does Dupixent work (mechanism of action)?

Dupixent blocks two substances in your body, called interleukin-4 (IL-4) and interleukin-13 (IL-13), from working. Too much IL-4 and IL-13 activity can cause swelling in parts of your body that lead to asthma, COPD, eczema, and other conditions. Blocking IL-4 and IL-13 from working can decrease the swelling that causes these conditions.

How is Dupixent supplied (dosage forms)?

Dupixent is available in the following dosage forms that are injected under the skin (subcutaneous).

  • 300 mg/2 mL (150 mg/mL) solution for injection, single-dose pre-filled syringe or pen
