This sounds very similar to a treatment that my daughter is due to start next year at a Cambridge allergy clinic in the UK. She'll have to take the peanut based medication every day. She will have the initial dose in a hospital in case she has a reaction and then take the remainder of the doses home. Every two weeks we'll go back to the hospital to increase the dose.
I'm very excited about the potential for this to keep her safer, but also terrified at the prospect of deliberately feeding her peanut.
