What is Dupixent, and what is it used for?
Dupixent is a prescription medicine used:
- to treat people aged 12 years and older with moderate-to-severe atopic dermatitis (eczema) that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies. Dupixent can be used with or without topical corticosteroids.
- with other asthma medicines for the maintenance treatment of moderate-to-severe asthma in people aged 12 years and older whose asthma is not controlled with their current asthma medicines. Dupixent helps prevent severe asthma attacks (exacerbations) and can improve your breathing. Dupixent may also help reduce the amount of oral corticosteroids you need while preventing severe asthma attacks and improving your breathing.

What drugs interact with Dupixent?
Avoid use of live vaccines in patients treated with Dupixent.
Immune responses to vaccination were assessed in a study in which subjects with atopic dermatitis were treated once weekly for 16 weeks with 300 mg of dupilumab (twice the recommended dosing frequency). After 12 weeks of Dupixent administration, subjects were vaccinated with a Tdap vaccine (Adacel®) and a meningococcal polysaccharide vaccine (Menomune®). Antibody responses to tetanus toxoid and serogroup C meningococcal polysaccharide were assessed 4 weeks later. Antibody responses to both tetanus vaccine and meningococcal polysaccharide vaccine were similar in dupilumab-treated and placebo-treated subjects. Immune responses to the other active components of the Adacel and Menomune vaccines were not assessed.
Dupixent (dupilumab) is an injection that treats atopic dermatitis (eczema) for people whose condition doesn't respond to prescription eczema creams and ointments. Dupixent can be used with or without topical corticosteroids. Inflammation and allergic reaction are side effects of Dupixent, among others.
