Eosinophilic esophagitis (EoE) is treated with medications, dietary changes, or a combination of both, and most people need ongoing treatment to keep the disease in remission. EoE is a chronic immune condition where white blood cells called eosinophils build up in the lining of the esophagus, causing inflammation, difficulty swallowing, and food impactions. A diagnosis requires a biopsy showing more than 15 eosinophils per high-power field under a microscope. The good news: several effective treatment paths exist, and you can work with your doctor to find the one that fits your life.
Acid-Suppressing Medications as First-Line Therapy
Proton pump inhibitors (PPIs) like omeprazole and pantoprazole are often the first treatment tried because they’re inexpensive, widely available, and taken as a simple pill. PPIs do more than just reduce acid. They have a direct anti-inflammatory effect on the esophageal lining that helps calm eosinophilic inflammation independent of acid suppression.
About 35% of newly diagnosed EoE patients achieve histological remission on PPIs alone, meaning their biopsy results drop below the diagnostic threshold. Among those initial responders, roughly 60% maintain that remission long-term while staying on the medication. That means PPIs work well for a meaningful subset of people, but the majority will need additional or alternative treatment. Your doctor will typically check your response with a follow-up endoscopy and biopsy 8 to 12 weeks after starting therapy.
Swallowed Steroid Medications
If PPIs don’t bring your eosinophil counts down, the next step is usually a topical corticosteroid designed to coat the esophagus. Unlike steroids you might take for asthma or joint pain, these are swallowed rather than inhaled, so the medication contacts the inflamed tissue directly. The two main options are budesonide and fluticasone.
In 2024, the FDA approved a purpose-built budesonide oral suspension called Eohilia, which comes in a stick pack you squeeze directly into your mouth. You shake the packet for at least 10 seconds, swallow the suspension without mixing it with food or liquid, then avoid eating or drinking for 30 minutes. After that waiting period, you rinse your mouth with water and spit it out to reduce the risk of oral yeast infections, the most common side effect of swallowed steroids.
Before Eohilia existed, doctors had patients mix nebulizer liquid (budesonide respules) with a thickening agent to create a homemade slurry. This approach is still used. The typical method involves emptying the respules into a cup, stirring in a few packets of sucralose sweetener (or a teaspoon of honey or applesauce) until the mixture reaches a thick, baby-food consistency, then swallowing it. The same 30-minute fasting rule applies. The goal with either version is to get a viscous coating to stick to the esophageal lining long enough to reduce inflammation.
Dietary Elimination
Because EoE is driven by an immune response to specific food proteins, removing the trigger food from your diet can put the disease into remission without any medication. The challenge is identifying which food is responsible.
The traditional approach was a six-food elimination diet (6FED), which removes milk, wheat, egg, soy, fish, and nuts all at once. A large multi-site trial conducted by the Consortium of Eosinophilic Gastrointestinal Disease Researchers found something surprising: eliminating milk alone achieved roughly the same 40% remission rate as eliminating all six foods. That finding reshaped how many gastroenterologists approach dietary treatment.
The current preferred strategy is called a “step-up” approach. You start by removing just one food, usually cow’s milk and all dairy products, then get a follow-up endoscopy to see if your eosinophil counts have dropped. If they haven’t, you eliminate a second food, then reassess. This process continues in stages (one food, two foods, four foods, six foods) until remission is achieved. It requires more endoscopies than the old method, but it means you only restrict the foods that are actually causing your disease, which makes the diet far more sustainable long-term.
Dietary therapy works best with the support of a dietitian experienced in EoE. Reading food labels becomes a daily habit, and hidden ingredients like whey, casein, or milk powder in processed foods can be easy to miss.
Biologic Therapy for Refractory Cases
Dupilumab, a biologic injection originally approved for eczema and asthma, is now FDA-approved for EoE in adults and children one year and older who weigh at least 15 kilograms (about 33 pounds). It works by blocking two immune signaling molecules that drive the allergic inflammation behind EoE.
For adults and children weighing 40 kg or more, the standard dose is a 300 mg injection given weekly. Children between 30 and 40 kg receive 300 mg every two weeks, and those between 15 and 30 kg receive 200 mg every two weeks. The injections are self-administered at home using a pre-filled syringe or pen, similar to how people manage other biologic medications. Dupilumab is generally reserved for people who haven’t responded adequately to PPIs, swallowed steroids, or dietary changes, partly because of its cost.
Esophageal Dilation for Narrowing
When EoE goes untreated or undertreated for years, chronic inflammation can lead to scarring and narrowing (strictures) of the esophagus. If you have a stricture causing significant swallowing difficulty or food impactions, your gastroenterologist may recommend esophageal dilation, a procedure where the narrowed area is gently stretched during an endoscopy.
Dilation treats the structural damage but not the underlying inflammation, so it’s always paired with one of the medical or dietary therapies above. In a study of 293 dilation procedures in EoE patients, the perforation rate was approximately 1%. Deep mucosal tears, which sound alarming but typically heal on their own, occurred in about 9% of cases. The risk is higher when strictures are located in the upper esophagus or are tight enough to prevent the endoscope from passing through. Most people notice an immediate improvement in swallowing after dilation, though some need repeat procedures.
Why Long-Term Treatment Matters
EoE is a chronic condition. When treatment is stopped, eosinophilic inflammation almost always returns, and persistent untreated inflammation drives the scarring and narrowing that cause the worst symptoms. This is why maintenance therapy, whether it’s a daily PPI, an ongoing swallowed steroid, or a sustained dietary restriction, is a core part of managing the disease rather than an optional add-on.
Once you’ve achieved remission, your doctor may try lowering your medication dose to find the minimum amount that keeps inflammation controlled. Follow-up endoscopies are the only reliable way to confirm that the esophagus is staying healthy, since symptoms don’t always match what’s happening at the tissue level. Some people feel fine while still having active inflammation on biopsy. The American College of Gastroenterology notes that gaps in care of two years or more are associated with progression to fibrostenotic disease, the scarring and stiffening of the esophagus that can become irreversible. Regular check-ins, even when you feel well, help prevent that progression.
Choosing Between Treatment Options
There is no single best treatment for EoE. The right choice depends on your preferences, how severe your disease is, and how you respond. Some people prefer the simplicity of a daily pill and start with a PPI. Others want to avoid long-term medication and pursue dietary elimination. Many end up combining approaches, using a swallowed steroid while also avoiding dairy, for example.
What matters most is that you’re on some form of ongoing therapy and getting periodic monitoring. EoE management has improved dramatically in the past decade. Between purpose-built medications, streamlined dietary protocols, and biologic options for difficult cases, most people can achieve and maintain remission with a plan that fits their life.
