Should non PA sibling do a food challenge

Sean will be sarting school this fall. He was tested at the allergists office for PA and he is not allergic. He has never had peanutbutter or peanut products.

The doc wants to do a food challenge in her office before he starts school. Is this what you have done? I don't want him to go to school and then have someone touch him with peanutbutter and he ends up having a reaction.

What have you guys done?

Thanks!

You could do that but if he doesn't react, you are not necessarily out of the woods since that might very well be his first exposure to peanut protein ever. You will have to have him try it again a few times before you will really know for sure.

Not that I'm necessarily advising it, but I tried it at home (mainly in the garage!) with Epipens and wipes handy. Our allergist actually agreed that it was O.K. since he had tested negative to all foods several times and has never had a known reaction to anything. Actually, the first time was at a friends' house using a toothpick and a tiny amount of PB. Waited at least 24 hours before trying any more. Gradually increased amounts each time.

I was nervous as **** but there were no reactions. Had there been one, I would have been prepared with my Epipen, Benadryl and 911.

Again, not advising but just pointing out that the first exposure to peanut does not cause a reaction. The body needs time to make antibodies. The second or third time are likely to show reactions if the child is truely allergic.

Good luck!

Yes- this is what I had done w/ non allergic sibling. She was tested at 5.5 before kindergarten started and tested negative. Had possible peanut exposure at 13mths. After the negative SPT we went for a challenge a few weeks later. You are in the office for hours, bring entertainment! Books etc. She passed the challenge and has the occasional pb food. It is nice not having to worry about her in food situations.

I plan on doing the same at the end of the month. Carson is starting preschool and so far(he has been tested 3x's) he is negative to peanuts and tree nuts. But I want to know for sure....so we just may have him eat a small piece in the office and see if everything is okay. I know it's no guarentee...I know 2 twin boys who ate pb up until 2nd grade, and now they are anaphylaxic to it!!!! But at least it will give me an idea, for now. I also plan to recheck his milk and also rub some on his arm(liek if a carton spilled at school) to see what *might* happen as well. His milk has conintued to drop, so hopefully he can sit around it with no problems. Good luck [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]

I am really scared for him to have a food challenge. I would hate for him to have PA as well. But, I guess it is better to find out in a dr. office then at a baseball game.

He does not even like the smell of pb, so I am not worried that he will get some and eat it.

I will call the doc and see when I can get him in.

Thanks,

PA DD's younger sibs had negative skin tests and had never been exposed to peanut after birth. They had minimal exposure in utero. Our allergist (Dr. Wood) was almost certain they were not allergic and did not think a challenge in the office was necessary.

Before they started kindergarten I took each child (and two Epipens) to a lounge down the hall from our local hospital's emergency room and did the challenge myself. They very gradually ate a bag of Reeses Pieces over 2-3 hours, starting with 1/2 piece, wait 15 minutes, 1 piece, wait 15 minutes, 2 pieces etc. Nobody had a reaction, but they didn't like the candy.

Carson has had 1 bite of a pb sandwich and spit it out, he didn't even like it....so I don't think I'll have a problem with him wanting to eat it, the testing would be more for school and how diligent(504 or not) I'd need to be with him. So with eating it once and 3 scratch/caprast's tests, I am hoping he stays negative(like his big sister)!! But I know that's no guarentee [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]

Just thought I'd add my experience here. I started 3 threads when I was going through this in March, so I'll just try to link those threads instead of re-telling the saga.

So from my experience - I don't think it is a bad idea to have them near medical help when trying it for the first time - but I also have come to realize that it isn't always the first time that gets you into trouble.
