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.
  • Dupixent works by blocking two proteins that contribute to a type of inflammation that plays a major role in atopic dermatitis and asthma.
  • Dupixent is not used to treat sudden breathing problems.
  • It is not known if Dupixent is safe and effective in children with atopic dermatitis under 12 years of age.
  • It is not known if Dupixent is safe and effective in children with asthma under 12 years of age.

What are the side effects of Dupixent?

Dupixent can cause serious side effects, including:

  • Allergic reactions (hypersensitivity), including a severe reaction known as anaphylaxis
  • Eye problems. If you have atopic dermatitis, tell your healthcare provider if you have any new or worsening eye problems, including eye pain or changes in vision.
  • Inflammation of your blood vessels. Rarely, this can happen in people with asthma who receive Dupixent. This may happen in people who also take a steroid medicine by mouth that is being stopped or the dose is being lowered. It is not known whether this is caused by Dupixent. Tell your healthcare provider right away if you have:

What drugs interact with Dupixent?

Live Vaccines

Avoid use of live vaccines in patients treated with Dupixent.

Non-Live Vaccines

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.
