Specific dosing varies from food to food, but the general concept includes an initial escalation day of serial, increasing, low doses of the food, followed by a buildup phase wherein a single higher dose is administered in the clinic followed by a 45 minute observation period, then the same dose is taken daily at home until the next visit 1-2 weeks later. This continues until a maintenance dose of the food is safely consumed which is generally a meal equivalent of the culprit food. There will be some circumstances where a "bite proof dose" will be the target, for highly allergic individuals. This will reduce severe reactions due to accidental exposures.
