Few days: For most food allergies, it usually only takes a few days before one starts feeling better. It may take longer for complete resolution of symptoms but if it has been longer than a week, consider another reason for the itching and see your doctor.

Several days: It may take several days (more than 3 -5 days) to notice relief. Transit time from the mouth to the anus may be 3 days and then the immune reaction may take a few additional days to clear.
