Written by: Heather Morse | Last reviewed: May 2022 | Last updated: July 2022

Dupixent® (dupilumab) is a maintenance drug used in combination with other medicines to treat moderate-to-severe asthma. It is prescribed for adults and children 6 and older whose asthma is not controlled with other asthma drugs.1

Dupixent may help reduce the use of oral corticosteroids needed to control asthma. It is not to be used as a rescue inhaler to treat sudden breathing problems.1

Dupixent is also approved to treat:1

  • Eosinophilic esophagitis (EOE) in adults and children 12 and older who weigh at least 88 pounds. Eosinophils are inflammatory cells that can contribute to the development of asthma.
  • Moderate-to-severe atopic dermatitis (eczema) in adults and children 6 months and older.
  • Chronic rhinosinusitis with nasal polyposis (CRSwNP) in adults.

How does Dupixent work?

Dupixent is a biologic drug designed for the treatment of allergic diseases. Biologics are drugs made from living cells. These cells can come from parts of the blood, proteins, viruses, or tissue. The process of making biologics turns products made from cells into drugs that can prevent, treat, and cure disease. These are different from most traditional drugs. Traditional drugs are made from chemicals in a lab. Their ingredients are not directly derived from living cells.1

Dupixent works by blocking 2 key proteins that contribute to the inflammation that may cause moderate-to-severe asthma. This may reduce severe flare-ups and oral corticosteroid use.1
