pIf your child has eaten something you later find out MAY have had traces of nuts and has not immediately reacted, how long should you monitor for a reaction?/p

Wow, this is a hard one. I am hoping that someone has a more definitive answer for you.
I know that I have read on this board that a reaction can occur up to 8 HOURS later. I'm not clear if that is a second reaction or if it could include a first reaction. That is why, if your child does goes into anaphylactic shock, you are generally kept in the hospital for 8 hours so they can monitor for a second reaction.
I had posted that when my son tries a new food I set my timer for 30 minutes. This is based solely on my experience with my son.
His reactions have been almost immediately.
When I first posted that, I did have someone come in and say that 30 minutes wasn't enough, that a reaction could occur up to 2 HOURS later.
Those are the only two time frames I have heard of - 2 hours and 8 hours. I'm not clear if it's possible for one to occur 24 hours after ingestion. Again, I am hoping that someone has a better answer for you.
I think, for me, if I didn't know for sure, I would monitor my child for the period of day left and then throughout the 8 hour night.
I am actually quite interested in seeing what responses you do get to this post. I think it's really important for all of us to know some time frame.

My son has had many mystery rashes in his two years, which we now think have been allergic reactions. (hives) I know we have suspects now for at least a few of them because we just found out he is allergic to chocolate. I know that with a few of his rashes he had just eaten chocolate. Anyway, our ped allergist told us that in the future, should he have an allergic reaction or a rash that we suspect is an allergic reaction, we should make a note of all foods he has eaten within the past [b]*24 hours*[/b] as well as any changes in enviroment (been around a cat? etc). She didn't come right out and say that allergic reactions could occur for up to 24hr, but that seems to be what she was inferring.

Matt's Mom, that sounds like a time-frame that I would feel comfortable with, despite having posted what I did. That's why I put the little caution sign beside my post because I really wasn't clear about how long I would watch - I've never had to. Jesse's reactions have always been immediate and we were kept in intensive care for more than 8 hours after his 3rd reaction (2nd anaphylactic). 24 hours sounds really safe to me.

One of our son's allergies is soy. He has a delayed response to soy. He vomits 2-6 hours after eating a significant amount, or he gets eczema the next day if he just gets a little.

Generally, if it is going to be a severe reaction it is going to occur within 30 minutes. The longest documented reaction that I know of is one that happened 20 hours later. From shrimp.

Thanks everyone! I feel a little more comfortable now knowing about how long I should watch. [img][/img]

I appreciate this. Nicholas' reactions are always 6-8 hours later. Makes it hard if he gets something different at night. Therefore, we obviously don't give him "new" foods late in the day. I'll pass this on to my husband so he knows how long to look.
Thanks for this topic!
