What is Dupixent

Dupixent contains the active ingredient dupilumab.

Dupilumab is a monoclonal antibody (a type of specialized protein) that blocks the action of proteins called interleukins (IL)-4 and IL-13. Both play a key role in the appearance of symptoms and signs of atopic dermatitis and asthma..

What is it used for

Dupixent is used to treat adults and adolescents12 years old and abovewith moderate to severe atopic dermatitis, also known as atopic eczema. Dupixent is also used to treat children from 6 months to 11 years old with severe atopic dermatitis (see sectionChildren and adolescents). Dupixent can be used with topical medications for eczema or alone.

Dupixent is also used, along with other asthma medications, for themaintenance treatmentof severe asthma in adults, adolescents, and children6 years old and abovewhose asthma is not controlled with their current medication (e.g. corticosteroids).

How Dupixent works

The use of Dupixent for atopic dermatitis (atopic eczema) may improve your skin condition and reduce itching. Dupixent has also shown improvement in symptoms of pain, anxiety, and depression associated with atopic dermatitis. Additionally, Dupixent helps to improve sleep disorders and overall quality of life.

Dupixent helps to prevent severe asthma attacks (exacerbations) and may improve lung function. Dupixent also may help to reduce the amount of another group of medications you need to control your asthma, called oral corticosteroids, while preventing severe asthma attacks and improving lung function.
