OIT stands for Oral immunotherapy, a drug class abbreviation.
Treatment for food allergy in which a patient eats tiny, gradually increasing daily amounts of the allergen, such as peanut, to raise the threshold that triggers a reaction. It aims to protect against accidental exposure rather than cure the allergy.
Example: Peanut OIT: up-dose to 300 mg protein today; observed 60 minutes, no reaction.
Usage notes
Palforzia, a standardized peanut allergen powder, was approved by the FDA in 2020 as the first OIT product. Allergic reactions, stomach pain and eosinophilic esophagitis can occur during treatment, and protection may fade if daily dosing stops. In 2024 omalizumab became the first medication approved to reduce reactions to multiple foods.
