A protein that causes an allergic reaction.


A doctor who specializes in the diagnosis and treatment of allergic disorders.


An abnormal immune system response to any stimulus.


A tissue sample.


Difficulty swallowing liquid or solid food.




A tube with a light and a camera on the end of it used to view the esophagus and other parts of the digestive system. It usually has a biopsy port for tissue sample collection.


A procedure in which an endoscope—a thin, flexible tube with a light and a camera on the end of it—is used to take a closer look at your esophagus.


A type of white blood cell involved in allergic reactions.

Eosinophilic Esophagitis (EoE)

A chronic, immune-mediated, inflammatory disease localized in the esophagus.


The muscular tube that carries food from the mouth to the stomach.


Patches of white specks (or white plaques) that line the esophageal wall.


When inflammation leads to scarring, narrowing, and formation of excessive fibrous tissue in the lining of the esophagus.


Vertical indentations in the esophageal wall.


A doctor who specializes in diagnosing and treating disorders of the digestive system, including the esophagus.


A doctor who specializes in diagnosing and treating diseases of the immune system.


The body’s response to tissue injury, irritation, or damage.


A buildup of tissue at the lower end of the esophagus that interferes with the passage of food.


A narrowing or constriction of the esophagus. Strictures may be temporary or permanent, depending on the cause.

Frequently asked questions

EoE is a chronic inflammatory disease characterized by the accumulation of a certain type of white blood cell (called an eosinophil) in the esophagus, which can lead to dysphagia (difficulty swallowing).

Your doctor is the best source of information about EoE and the symptoms you may be experiencing. You can use this helpful Doctor Discussion Guide to get that conversation started.

EOHILIA is the first and only 12-week, FDA-approved oral treatment designed for people with EoE 11 years and older. EOHILIA is intended to provide relief* from EoE inflammation. EOHILIA has not been shown to be safe and effective for longer than 12 weeks.

For more information about EOHILIA, click here.

*Relief is defined as a decrease in eosinophils (a type of white blood cell) in the esophagus and improvement in dysphagia (difficulty swallowing), as demonstrated by EOHILIA in two 12-week clinical trials.

Make sure to see the detailed Instructions for Use that comes with EOHILIA for information about how to prepare and take it and how to properly store and throw away (dispose of) used EOHILIA stick packs.

Take EOHILIA exactly as your healthcare provider tells you:

  • EOHILIA is taken by mouth 2 times a day. (An easy schedule to remember and stick to is “Once in the morning. Once in the evening.”)
  • Do not mix EOHILIA with food or liquid
  • Avoid drinking grapefruit juice during treatment with EOHILIA
  • Do not eat or drink at the same time as taking EOHILIA. Wait until at least 30 minutes to eat or drink after taking EOHILIA

Do not change your dose or stop taking EOHILIA unless your healthcare provider tells you.

The EOHILIA on-the-go stick packs do not need to be refrigerated. So treatment is always ready to go.

EOHILIA should be stored at controlled room temperature between 36°F to 77°F (2°C to 25°C). Do NOT freeze.

EOHILIA helps to address inflammation in the esophagus.

EOHILIA is a liquid-like form of budesonide (a corticosteroid) specifically formulated to treat inflammation in the esophagus. While the exact way corticosteroids work on EoE inflammation is not known, EOHILIA works on a wide range of inflammatory cells.

While results may vary, the majority of people who took EOHILIA in clinical studies had fewer dysphagia symptoms and inflammation related to EoE after 12 weeks. Learn more about the clinical study results for EOHILIA here.

The safety of EOHILIA was established in a 12-week clinical study of 318 adult and adolescent patients 11 years of age and older with EoE. The most common side effects of EOHILIA include: respiratory tract infection; sore throat; fungal infections of the mouth, throat, and esophagus (thrush); adrenal suppression; headache; and acid-related damage to the esophagus lining (erosive infection of the stomach and intestine [gastroenteritis]). These are not all the possible side effects of EOHILIA. Safety results were similar in a second, smaller study of 92 patients.

EOHILIA may cause serious side effects, including hypercorticism (effects of having too much corticosteroid medicine in your blood), adrenal suppression (a condition in which the adrenal glands do not make enough steroid hormones), immunosuppression (decreased ability of your body to fight infections) and increased risk of infection, erosive esophagitis (acid-related damage to the esophagus lining), effect on growth, worsening of allergies, and Kaposi’s sarcoma.

Be sure to talk to your or your child’s doctor about any side effects that are bothersome or do not go away.

Make sure to ask your doctor about potential side effects. It’s an important part of the conversation, and it’s important for you to understand both the benefits and the risks of treatment.

For additional information, please see Important Safety Information and Patient Information and talk to your doctor.

Do not take EOHILIA if you are allergic to budesonide or any of the ingredients in EOHILIA. Please click for Patient Information and Instructions for Use.

EOHILIA, like many other prescription medications, will likely need approval by your health insurance company for it to be covered. The doctor’s office typically takes 1-2 weeks to complete this process. Stay in touch with your doctor’s office or pharmacist while they work through insurance coverage for EOHILIA.

For more information about the prescription process, download the EOHILIA Copay FAQ Guide.

Yes, the EOHILIA Patient Support and Copay Program provides financial support for commercially insured patients who qualify for the program. Patients are not eligible if they are beneficiaries of, or any part of the prescription is covered by, a government-funded healthcare program. For additional eligibility and restrictions, click here.

The EOHILIA Patient Support and Copay Program is here to help guide you along your EoE treatment journey. By joining it, you’ll receive educational email content to help you have informed discussions with your doctor. Patients can also sign up to receive a copay card to bring to their pharmacy to start on EOHILIA for as little as $0.†
