#1 At-Home
Food Allergy Treatment

Curex provides at-home sublingual immunotherapy (SLIT) for food allergies. Instead of injections or eating the allergen, you place a small number of personalized allergy drops under your tongue each day. The drops are made from medical-grade extracts of the foods you're allergic to, and over time they help your immune system become less reactive — reducing the risk of a severe reaction from accidental exposure. Your treatment is prescribed and overseen by a board-certified allergist, and everything is managed from home.

The duration of treatment varies for each individual. 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 tolerate accidental exposure to the allergen. At the end of this period, providers may recommend undergoing an in-person food challenge, supervised by a clinician, if the patient is interested in confirming their tolerance.

Sublingual immunotherapy works by exposing your immune system to small, controlled amounts of an allergen placed under the tongue, where specialized immune cells are especially good at building tolerance. With consistent daily dosing, your body gradually learns to react less to that allergen — a process called desensitization.

Rather than masking symptoms, the goal is to retrain the underlying immune response so that accidental exposures are less likely to trigger a serious reaction. Because the dose is low and absorbed under the tongue, SLIT has a favorable safety profile compared with approaches that require eating the allergen.

Curex treats over 90 food allergies, including the most common ones: peanuts, tree nuts, milk, eggs, wheat, soy, fish, shellfish, and sesame. Your drops are custom-formulated to your specific allergens based on your testing and history.

We also treat environmental allergies such as pollens, dust mites, mold, and pet dander. If you're not sure whether your allergens are covered, a Curex clinician can confirm during your consultation.

Curex clinicians prescribe food allergy drops that are prepared at a leading allergy immunotherapy pharmacy, Allergychoices, specifically for you and shipped to you every three months. The composition of sublingual food allergy drops (SLIT) varies depending on an individual's specific allergies, as determined by allergy testing.

Sublingual food immunotherapy (SLIT) involves medical-grade allergen extracts and glycerin in its formulation. Each treatment is tailored to the patient's unique food allergies and allergy history. Our formulation is phenol-free, ensuring a natural treatment experience. Moreover, it can be self-administered at home.

At Curex we treat food allergies, which are caused by your immune system reacting to a food when it doesn't need to.

With a food intolerance or sensitivity, your immune system isn't responsible for the symptoms. Most of the time it's an inability to digest the food's proteins or carbohydrates. We do not treat food sensitivities.

For example, a milk allergy is different from lactose intolerance. A milk allergy can cause anaphylaxis and involves allergic antibodies targeting a protein in milk. Lactose intolerance, on the other hand, causes digestion issues and involves a reduced level of lactase — an enzyme needed to digest lactose, the common sugar found in milk.

Generally, food allergies can be life-threatening, whereas sensitivities or intolerances can cause discomfort but are rarely life-threatening.

Curex clinicians will help you determine whether your food reaction is caused by an allergy or an intolerance / sensitivity.

At Curex we focus on treating allergic reactions to food. Being allergic to milk is different from not being able to digest it properly because of lactose intolerance.

Curex clinicians will help you determine whether you are allergic to milk or are unable to digest it properly because of lactose intolerance.

Both SLIT and OIT are forms of immunotherapy that build tolerance to an allergen, but they're delivered very differently. OIT (oral immunotherapy) involves eating gradually increasing amounts of the actual allergen — for example, small but rising doses of peanut — usually under close supervision because of the reaction risk.

SLIT (sublingual immunotherapy), which is what Curex uses, delivers a much smaller dose as drops held under the tongue. Because the dose is lower and isn't eaten as food, SLIT is generally considered to have a gentler safety profile and can be taken at home, without the daily food dosing that OIT requires.

Sublingual allergy drops (SLIT) are widely regarded as having a superior safety profile compared to Oral Immunotherapy (OIT), primarily due to the method of administration and the significantly lower dosage used in SLIT.

A recent study found that patients undergoing food SLIT treatment rarely experience side effects, and when they do, these are typically mild and limited to temporary itching in the mouth and/or throat. If these symptoms are really bothersome, our clinicians can adjust the strength of the extract to mitigate the problem.

While severe adverse reactions, such as anaphylactic shock, are extremely rare, there have been documented cases in individuals with a history of anaphylaxis. Patients with a known history of anaphylaxis will be carefully evaluated by our clinical team to determine if food SLIT is a safe and appropriate option for them.

Our clinical team, together with our pharmacy partner, Allergychoices, follow protocols that have successfully treated over 50,000 patients with food SLIT.

Although the safety record is excellent, our providers carefully evaluate the risk profile of each patient to ensure SLIT is appropriate and safe. As a precaution, we prescribe and require epinephrine for every patient to have on hand in case of an emergency.

We strongly recommend having another adult with an EpiPen available when you take your allergy drops for the first time and when increasing the dosage. This ensures added safety and immediate support in case of any unexpected reactions.

All patients who are prescribed food allergy drops through Curex are required to have an epinephrine device. Although extremely rare, a severe allergic reaction is possible, and epinephrine can be life-saving. Anaphylaxis action plans — including instructions on correct epinephrine use — are provided to all patients starting on food allergy drops.

Once you sign up and complete your medical history form, you'll have your first clinical consultation with a Curex clinician. During this call, we prepare and finalize your test order. The process is designed to be straightforward and convenient.

The test requires a simple, easy blood draw. We utilize ImmunoCAP IgE, sIgE, and component testing to confirm the diagnosis. If you choose to have your test conducted at a local lab, you can typically expect results within 5–7 business days. If you opt for other testing methods, the timing may vary slightly due to scheduling and logistical factors.

If you have food test results from another clinic, you should upload them during the medical onboarding questionnaire. We'll retest you after one year on the food allergy drops to check whether your food IgE levels have decreased. It's important to monitor these levels as a measure of treatment success.

Yes. Curex accepts the majority of insurance plans across the United States, including Aetna, Anthem, UnitedHealthcare, Humana, and many others. Clinical consultations and allergy testing are billed to insurance, and we cap copays at $500/year. We also accept HSA and FSA payments.

If you don't have insurance or have a high-deductible plan, self-pay is available — your monthly subscription covers your allergy drops and shipping.

Yes. Curex treats both children and adults. Children as young as age 2 can begin treatment when it's appropriate for them, as determined by a board-certified allergist who reviews your child's history and test results.

Many families find the at-home drops easier than other options because there are no needles and no weekly clinic visits — just a couple of drops under the tongue each day.

Curex is an online allergy clinic that makes immunotherapy accessible from home. We connect you with board-certified allergists, handle your testing, and ship personalized sublingual allergy drops to your door — so you can treat the root cause of your food (and environmental) allergies without weekly office visits. Your treatment is overseen by licensed clinicians, with a care team you can message anytime.

You can cancel at any time. However, please note that if you received treatment recently, we'll need to collect any remaining payments for that treatment on your account. Additionally, if you had any telehealth visits, it can take up to three months for insurance to process each claim — these may be billed to you after you cancel if they haven't been processed already.
