Is this considered a peanut allergy or not?
Hi, my baby had a positive skin prick test for peanuts but passed an oral challenge in the doctor’s office. How worried would you be about a future reaction/anaphylaxis? The allergist said baby’s positive skin prick means sensitivity meaning baby has IgE antibodies (no blood test was done) and high risk for allergy, especially since baby has eczema. She also said to give peanut butter twice a week to maintain tolerance and prevent future reactions, but didn’t give a clear answer to how long we need to do this. Baby was also prescribed an epipen just in case but unsure how long we need to keep carrying one. At what point can you say peanuts are no longer a concern and no longer need to give weekly to maintain tolerance or no longer need epipen? Do you retest later on to confirm no longer has antibodies or skin prick reaction, or is this just a forever thing? Baby has had peanut butter 4 times within the 3 weeks after the oral food challenge and no reaction so far (about 1 tbsp each time).
