The first FU-OFCs were performed at 6 months of age, and patients were randomly allocated to cow’s milk (n = 11) or soy (n = 12) challenge starting groups. Second and third FU-OFCs were performed at 2-month intervals in a crossed and switched-over manner.Results: Tolerance rates to cow’s milk and soy were 27.3% and 75.0% at 6 months of age, 41.7% and 90.9% at 8 months and 63.6% and 91.7% at 10 months, respectively. Patients outgrew cow’s milk and soy intolerance at age 20 and 14 months.Conclusions: In infantile FPIES, the first FU-OFC should be performed with soy at 6–8 months of age and cow’s milk FU-OFC should be conducted at over 12 months of age. Infants with FPIES were observed to outgrow food sensitivities during the first 2 years of life.
