What is Eosinophilic Esophagitis (EoE)?

Eosinophilic esophagitis (EoE) is a chronic condition that can damage the esophagus over time. People with EoE have inflammation in the esophagus, contributing to difficulty swallowing and other symptoms.

Those living with EoE:

Can experience difficulty swallowing, chest pain, or food impaction
May avoid certain foods to help reduce symptoms
May modify foods, by blending or adding sauce, to help make swallowing easier
Can be misdiagnosed with a food allergy or gastroesophageal reflux disease (GERD)

Breakthrough Treatment
for EoE

Pills (proton pump inhibitors), slurries (swallowed topical steroids), and food elimination diets may provide symptom relief. DUPIXENT works differently. Here's how:

DUPIXENT targets an underlying source of inflammation, which contributes to EoE.
DUPIXENT is a injectable treatment given under the skin (subcutaneous injection). It is not a steroid or immunosuppressant.

The most common side effects in patients with eosinophilic esophagitis include:
injection site reactions, upper
respiratory tract infections, cold sores
in your mouth or on your lips, and joint pain (arthralgia).
