Is OIT a "cure" for food allergies?
No. OIT is a form of desensitization allowing individuals to eat the food without causing an allergic reaction. To maintain the desensitization, the food must be eaten on a daily basis even after the desensitization process has been completed. If the individual stops eating the food, the immune system will return to the original allergic state.
Who are good candidates for OIT?
Individuals who have experienced an allergic reaction after ingestion of a food AND also have shown evidence of the allergy to that food on skin and/or blood testing. OIT only treats food allergies that are caused by the IgE allergic antibody. Individuals who lack this antibody on a skin or blood allergy test, will not benefit from OIT.
How effective is OIT?
Very effective. In academic centers where rigid research protocols must be followed due to regulations, the success rate of oral immunotherapy is 80-90%. In contrast, allergists in private practice are able to customize and modify the protocols for each individual based on the sensitivity level of the allergy and the progress during the treatment.

Yes, we have successfully desensitized people with sIgE levels greater than 100. We have taken patients from having a severe anaphylactic reaction from a spec of the food to eating a handful of the allergenic food without any problems.
How successful is OIT?
OIT has provided a 60–80% success rate for peanut, egg and milk allergies in clinical trials. Success is measured by food challenges that assess tolerance levels. An allergist will give a patient the allergenic food at three times the amount of their daily dose. If they can consume this amount without negative side effects, they can move to a maintenance dose. If a reaction is experienced, the OIT will resume.
Can you take OIT every day?
After all tests have been passed, you can continue the simple process of taking doses each day. Successful OIT should lead to the allergic food being integrated into your diet without fear of allergic reactions. But you will need to continue maintenance doses to ensure your immune system doesn’t lose tolerance.
