About Dupixent

What is
Dupixent for?

Dupixent is used with other asthma medicines for the maintenance treatment of severe asthma in adults and adolescents (aged 12 and older) whose asthma is not controlled with their current asthma medicines. This medicine contains the active substance dupilumab.

Asthma affects the airflow in your lungs

Your lungs contain small tubes that bring air in and out of it called bronchioles. Asthma affects bronchioles and larger airway tubes called bronchi.

  • Liquid prescription medications are exempt from the onboard liquid restrictions in some countries, but you will still need to declare them during security screening.
