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 of atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), nodular prurigo (NP), eosinophilic esophagitis (EoE), and chronic obstructive pulmonary disease (COPD).

Indications

Dupixent is used to treat adults and adolescents12 years and olderwith moderate to severe atopic dermatitis, also known as atopic eczema. Dupixent is also used to treat children 6 months to 11 years with severe atopic dermatitis. Dupixent can be used with topical medications for eczema or alone.

Dupixent is also used, along with other asthma medications, for the maintenance treatment of severe asthma in adults, adolescents, and children 6 years and older whose asthma is not controlled with their current medication (e.g., corticosteroids).

Dupixent is also used, along with other medications, for the maintenance treatment of CRSwNP in adults whose disease is not controlled with their current CRSwNP medication. Dupixent can also reduce the need for surgery and the need for systemic corticosteroids.

Dupixent is also used to treat adults with moderate to severe nodular prurigo (NP), also known as chronic nodular prurigo (CNP). Dupixent can be used with topical medications for NP or alone.

Dupixent is also used to treat adults, adolescents, and children 1 year and older, with a minimum weight of 15 kg, with eosinophilic esophagitis (EoE).

Dupixent is also used, along with other medications, for the maintenance treatment of chronic obstructive pulmonary disease (COPD) in adults with uncontrolled COPD.

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 improve sleep disorders and overall quality of life.

Dupixent helps prevent severe asthma attacks (exacerbations) and may improve lung function. Dupixent can also help 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.

Dupixent helps prevent moderate to severe COPD exacerbations and may improve lung function. Dupixent can also help improve overall COPD symptoms.
