There are a number of small studies focusing on the use of oral immunotherapy for the treatment of peanut allergy. These studies involve giving increasing amounts of peanut flour (often in gelatin capsules) to swallow on a daily basis, for a period of weeks to months. After this time period, an oral challenge to peanut is used to determine how much peanut the person could then tolerate without experiencing an allergic reaction. A few studies have shown that after children had undergone oral immunotherapy to peanut for many months, they could then eat a large amount of peanuts (approximately 20) without experiencing an allergic reaction. Unfortunately, almost all of these children experienced some form of allergic reaction during the course of the oral peanut immunotherapy.
