CUREX HAS BEEN FEATURED IN
Permanent relief is possible
- We’re the largest online allergy clinic and have developed a first-of-its-kind treatment for food sensitivities, a condition that affects 20-30% of Americans.
- This is not a supplement but immunotherapy backed by science and prescribed by doctors.
The treatment is not appropriate for Food Protein-Induced Enterocolitis Syndrome (FPIES) and Food Protein-Induced Allergic Proctocolitis (FPIAP).
Easier than brushing your teeth
Food sensitivity drops contain allergenic food extracts that desensitize your immune system over time.
Simply place them under your tongue for 2 minutes a day and start seeing relief in as little as 3-6 months.
We treat over 90 food sensitivities

Real science for real results
Immunotherapy has long been a proven treatment for IgE-mediated allergies, such as peanut or shellfish allergies, which can trigger severe, sometimes life-threatening reactions. However, for non-IgE-mediated food sensitivities, which primarily affect the digestive tract rather than the immune system, the standard approach has traditionally been strict avoidance of the trigger foods.
While avoidance can help manage symptoms, many patients find this approach unsatisfactory. They often turn to unproven supplements like enzymes, probiotics, or over-the-counter digestive aids. While these may provide some relief for certain individuals, they do not address the underlying sensitivity or promote lasting tolerance.
Curex takes a different, clinically grounded approach. Our food sensitivity treatment uses a form of immunotherapy known as sublingual immunotherapy (SLIT), which has shown promise in early studies. SLIT works by gradually retraining the immune system to tolerate specific food proteins. Our therapy is prepared allergy drops, prescribed and supervised by a specialized medical team.
While this approach is considered experimental, it is supported by emerging scientific evidence and the clinical experience of our healthcare providers. Many patients have already achieved meaningful improvements, experiencing greater dietary freedom and reduced symptom severity.
Food sensitivity testing with Curex
Why IgG Testing Matters
Unlike IgE-mediated allergies, which cause immediate and sometimes severe reactions, IgG-mediated food sensitivities involve delayed immune responses. Differentiating between these two types is critical for developing a safe and effective treatment plan. Testing for IgG reactivity helps uncover chronic food triggers that might be silently impacting your health.
Comprehensive IgG Testing Options
We specialize in identifying non-IgE-mediated food sensitivities using advanced IgG antibody testing. These sensitivities often go undiagnosed but can contribute to symptoms such as bloating, fatigue, headaches, brain fog, and skin issues—often delayed and harder to trace than classic allergic reactions.
What We Test
Curex offers IgG testing for over 260 of the most commonly consumed foods, including dairy, grains, nuts, fruits, vegetables, meats, and more. This broad panel ensures we can identify even subtle sensitivities and design an exposure plan tailored to your needs.
Testing Modalities – Flexible Options Nationwide
We make it easy to get tested, wherever you are:
At-Home Collection Kit:
If you’re in a remote area or prefer the comfort of home, we can ship an easy-to-use test kit straight to your door.
Use Your Own Lab:
Already working with a local lab or provider? We’ll supply you with a requisition form that includes all the necessary allergen codes for testing.
Take the First Step
Food sensitivity testing is the foundation of your personalized treatment at Curex. By accurately identifying your IgG reactivities, we can build a targeted exposure therapy plan to help your body gradually build tolerance—backed by our clinical protocols and patient-first approach.

Got questions? We have answers.
Is this safe for anaphylactic allergies?
Yes, our food sensitivity drops are custom-formulated for each patient and diluted to a level that is highly unlikely to trigger an anaphylactic reaction. At the same time, the dosage remains clinically meaningful to help gradually build tolerance to the specific foods you are sensitive to.
How long until I can reintroduce foods?
The duration of treatment varies for everyone. Curex clinicians will work closely with you to determine the right time to complete your treatment based on your progress.Typically, the recommended treatment lasts 3-5 years. This period is usually sufficient to desensitize the patient and allow them to safely reintroduce foods in question.
What if I miss a dose?
If you miss a dose, simply resume with your next scheduled dose as soon as possible. There’s no need to double up—just continue with your regular dosing schedule.
Can children enroll?
Absolutely. Children can enroll in the program, and in many cases, earlier intervention leads to faster and more effective outcomes, as their immune systems are still in key stages of development and adaptation.At Curex, we prescribe sublingual drops for children as young as 2 years old, provided the clinician believes the patient will benefit and can follow the treatment plan with the help of their parent or guardian.
