Oral immunotherapy (OIT) is a process that regularly exposes the patient to increasing amounts of the foods they are allergic to, with the goal of desensitizing the body and protecting against anaphylaxis due to accidental exposures. Research over the last two decades supports the safety and efficacy of OIT for patients with single and multiple food allergies.
OIT is not a cure. It is a desensitization. In order to maintain desensitization, a patient needs to continue to eat the foods they have been desensitized to on a regular basis.
Research shows that OIT is approximately 85% effective when supervised by an expert care team who specialize in food allergy treatment. At Latitude, 92% of our OIT patients of all ages have successfully achieved maintenance — and that number is 97% for our patients under 4 years old. While there are a small number of clinical reasons a patient may need to stop therapy, those who do not complete the OIT process primarily pause treatment due to the time commitment or other lifestyle constraints.
For more background on the long-term impact of oral immunotherapy, we recommend the following published studies and meta-analysis:
IgE-mediated food allergies can be treated with oral immunotherapy and multiple allergens can be treated together. Our allergists work with each patient to weigh the benefits and the burden of the treatment for each allergen. Below are results of clinical studies and relevant reviews for treatment of specific food allergens.
Peanut
Wheat
Cow’s Milk
Egg
Tree Nuts (Walnut, Pecan, Cashew, Pistachio, Hazelnut, Almond, Brazil Nut, Macadamia)
Fish & Shellfish
Sesame
Yes, we treat multiple food allergies at the same time. For more background on oral immunotherapy for multiple foods — with and without the use of anti-IgE Xolair (omalizumab) — we recommend the following published studies and meta-analysis:
It is possible to have an allergic reaction during oral immunotherapy (OIT). But at Latitude, we have specific protocols and supports in place to increase safety in the office for updose appointments and at home for daily dosing. Our data, validated and presented by Weill Cornell Medicine at the 2025 meeting of the American Academy of Allergy, Asthma and Immunology (AAAAI), showed that only 5% of doses in over 1,000 OIT patients caused any reaction, and the overwhelming majority were mild, like an itchy mouth or stomachache. From this large sample of real-world patients, reactions during dosing at home were uncommon and did not derail treatment schedules.
For more information about the risks and benefits of OIT, we recommend the following published studies and meta-analysis:
It is possible to have an allergic reaction while going through OIT. Our goal is to have a patient progress through treatment at a very slow and safe pace to reduce the risk of reaction and minimize unpleasant side effects.
We have several specific protocols in place to increase safety in the office and at home:
Our data, validated and presented by Weill Cornell Medicine at the 2025 meeting of the American Academy of Allergy, Asthma and Immunology (AAAAI), showed that only 5% of doses in over 1,000 OIT patients caused any reaction, and the overwhelming majority were mild, like an itchy mouth or stomachache. From this large sample of real-world patients, reactions during dosing at home were uncommon and did not derail treatment schedules.
We look forward to partnering with you on your patient’s care. While there are some underlying medical conditions that may preclude treatment, most patients can be treated with oral immunotherapy. We provide OIT for patients as young as 9 months old and adults. When we discuss the benefits and risks with a patient and their family, we address the following:
Please reach out to our clinical team at (888) 528-1592 if you have a question about a specific patient profile.
Yes, while our clinicians are focused on food allergy, we do take extra steps with each visit to ensure that asthma and other underlying allergic conditions are well-controlled. We encourage direct communication between our clinicians and the patient’s other providers to ensure these other conditions are monitored.
Xolair (omalizumab) is an anti-IgE monoclonal antibody by Genentech and Novartis that works by inhibiting the allergic reaction process. On February 16, 2024, it was approved by the FDA for the reduction of food allergic reactions, including anaphylaxis, in people with food allergies. It is also FDA approved for use in children over age 6 with asthma and in children over age 12 with chronic urticaria (hives). At Latitude, we offer Xolair in conjunction with OIT to increase safety for some patients. If our allergist prescribes this medication, our patient care team will work closely with the patient and their insurance plan to understand their coverage and any out-of-pocket costs before proceeding with treatment.

Our clinicians will carefully review all food allergy treatment options with the patient to determine the best personalized plan for their family.
Early introduction of peanut and egg is recommended, by the American Academy of Pediatrics (AAP), between 4 to 6 months of age. There may also be potential benefit to early introduction of dairy and wheat before 12 months. Within that recommendation, it is important to accurately diagnose any suspected food allergy and take into account individuals who may be at higher risk of developing food allergies. Below is the current guidance from the AAP and NIAID, as well as a few of the pivotal studies, including the LEAP studies, that have dramatically shifted early introduction recommendations in the last few years:
We encourage pediatricians to refer infants when a food allergy is already suspected for accurate diagnosis. Infants with eczema and those at a higher risk of developing a food allergy can be referred to offer early introduction, in the interest of prevention.
Our aim is to partner with you to diagnose and care for your patients’ food allergies.

Referrals can be sent directly via email to [email protected], by phone (888) 528-1592 or:
We are also happy to provide your office with literature to distribute to referred patients. Please contact us to receive those materials.
We can provide treatment for any clinically diagnosed (IgE-mediated) food allergy.
It is common for patients and even some healthcare providers to misdiagnose a food allergy. IgE-mediated food allergy can result in a life-threatening allergic reaction. On the other hand, a non-immune mediated adverse food reaction, while unpleasant, does not pose risk of anaphylaxis. When a non-immune mediated adverse food reaction is misdiagnosed as an IgE-mediated food allergy, a patient may unnecessarily restrict what they eat.
At Latitude, we take the necessary steps to accurately diagnose a food allergy to avoid unnecessary dietary limitations. This allows patients to bring some of their favorite foods back into their lives or to try new foods for the very first time.
Once a patient is referred to us, we follow up with them within one business day to schedule their initial appointment. Our goal is to have your referred patient seen for an initial appointment within a few weeks — if not sooner.
During the initial appointments, we will ensure that the patient has an accurate diagnosis and a personalized treatment plan, which we will share with the referring clinician.
For patients’ convenience, we offer telemedicine and in-person visits in our multiple Bay Area, Southern California, and New York City clinics.
Our clinicians and staff are available to come to your practice to meet you and provide tailored presentations on food allergy to your providers and staff. We are also happy to arrange a tour of our clinic and we welcome your questions at [email protected] or via our contact form.
