Is food allergy can be treated through immunotherapy or anti ige therapy ?

No: It is not recommended to use immunotherapy for treatment of food allergy. There are studies being done to try to desensitize by giving small amounts of the food frequently but these are still in a research phase. Anti-ige treatment with omulazimab is approve for asthma treatment in the us and it will often make the patient less reactive to foods they are allergic to.
