How does this medication work? What will it do for me?
Dupilumab belongs to the class of medications called immunomodulators, more specifically interleukin inhibitors. It is used by adults and children 12 years of age and older to treat moderate-to-severe atopic dermatitis (sometimes referred to as eczema) when topical medications are not controlling the symptoms or are not appropriate. It may be used alone or with corticosteroid creams and ointments.
Dupilumab blocks the action of interleukin, a protein in the body which causes inflammation. This reduces symptoms of atopic dermatitis, such as redness, itching, and inflamed skin.
This medication may be available under multiple brand names and/or in several different forms.
