There is currently no cure for food allergy, but treatments are currently being investigated. As a result, the current management of food allergy involves avoiding the offending food and having the medications necessary for the treatment of allergic reactions to foods. You may be given a Food Allergy Action Plan, which describes how to treat an allergic reaction.
Injectable epinephrine and antihistamines can be used to alleviate symptoms resulting from accidental exposures, but the recommended approach is complete avoidance of the suspected food.
