Food Allergy Treatment

Get Started with Oral Immunotherapy

Avoidance is no longer the only answer when a food allergy is diagnosed. You now have the option to take control of food allergies with treatment options like oral immunotherapy (OIT), which can protect against accidental exposures to food allergens, and may improve quality of life. Research has proven OIT to not only be safe but also approximately 85% effective when performed under the care of a clinician that specializes in food allergy treatment. We offer OIT for single and multiple allergies for adults and children as young as 1 year old. OIT with Xolair is also available to our patients over 4 years old.

Latitude was founded by food allergic families, that understand first-hand what it is like to live with the avoidance of foods. We know accidents happen — no matter how many labels you read, or how many foods you prepare, or the questions you ask — at social events, restaurants or school. Our lives have been changed by our own children’s experiences being treated with oral immunotherapy. 

What is Oral Immunotherapy (OIT)?

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 severe reaction to accidental exposures. We offer OIT for single and multiple food allergies to any food, including common allergens such as egg, milk, peanut, tree nuts, wheat, soy, seafood, sesame and other seeds. Our clinical team will determine whether you are a good candidate for oral immunotherapy, taking into account any existing medical conditions and your family’s lifestyle.

We offer OIT, with and without Xolair, and we are among the first clinics to offer Palforzia — the first FDA approved OIT treatment for peanut allergy.

Oral Immunotherapy Experience

Lily, mom of an OIT patient: Highly recommended. And as we go through the OIT process we have seen them for almost a year now. We feel SO LUCKY to have found them. My pediatrician in Burlingame asks about them along with other pediatrician friends. Their offices are the epitome of what you would want your allergic kid to experience at an allergist and this is critical during COVID times. It is one of the few places we really feel comfortable in.

Evidence based protocols

Thousands of patients have safely completed oral immunotherapy around the world. Latitude uses evidence-based protocols that are based on clinical studies from leading research institutions such as Stanford, UCSF, Duke, Baylor and others.

What does the process look like?

Diagnostic Process

After a thorough review and assessment has been done, an accurate diagnosis will be made. Our clinicians will design a customized OIT treatment plan based on the personal needs and the foods that you are truly allergic to and will be desensitized to.

Initial Dosing

The first initial dose starts with a series of very small doses under the supervision of a clinician. Typically this may last 2 hours during this visit. Doses are mixed with foods such as pudding or applesauce. This dose will then be taken at home every day for two weeks.


After two weeks of home dosing, the next dose is increased incrementally in the clinic, under observation. These updose visits occur every two to four weeks until the desired maintenance dose is reached. Each visit is typically an hour and a half over a period of 6 – 12 months. This is done under supervision of a clinician at all times.


After reaching a specific amount of food over time, the patient achieves “maintenance” as an end point. In order to maintain desensitization, a patient will continue to eat the foods they have been desensitized to every day. Once maintenance is achieved, patients realize a life changing level of protection that results in reduced anxiety around food and improvement in quality of life.
