Dupixent Injection: Uses, Side Effects, Dosage & More


Dupixent (dupilumab) is a brand-name prescription drug. It’s used to improve the following conditions:

  • Moderate to severe eczema (atopic dermatitis). It’s given to adults and children ages 6 years and older when symptoms can’t be improved with popular prescription drugs, or when those drugs should not be used.
  • Moderate to severe asthma. It’s taken by adults and children ages 12 years and older with eosinophilic asthma or oral corticosteroid-dependent asthma. It’s used to maintain treatment. Rescue inhalers can still be used as required for asthma attacks or symptoms such as trouble breathing. Experts advise people to never use Dupixent to treat a sudden asthma attack.
  • Chronic rhinosinusitis with nasal polyps. It’s prescribed for adults whose symptoms are not well controlled. It’s used as an add-on to maintenance treatment.

Dupixent is available in single-dose prefilled syringes and pens. It’s administered as a subcutaneous injection (beneath the skin). Dupixent is available in two doses: a 200-mg/1.14-mL solution and a 300-mg/2-mL solution. You can get it at your doctor’s office or give yourself injections at home after you learn how. You and your doctor can talk about the best option for you. How often you take this medication depends on your age and the condition you’re treating.
