So far every reaction I've read about on this board has mentioned only hives and swelling. My son vomited quite a bit about 30-45 minutes after he ate a peanut butter cookie (in addition to a few hives and some swelling around his eyes). Has anyone else experienced this after an exposure? How quickly did you or your child react the first time and subsequent times?

Vomiting has always been a part of my set of symptoms. Note that I started as 'sensitive' and have progressed to anaphylactic after 38 years of accidental exposures. I would start treating this as very serious and perhaps your son will not then progress to the 'minute or less' state of reaction.

My soon to be 6 year old daughter reacts with vomitting about 30 minutes after ingestion (although the nausea starts a little sooner). She has only ingested peanut butter once (during an oral challenge done under medical supervision last summer). Her eye swelled when she touched a table that had been used for a craft involving peanut-butter about 2 years ago (she probably rubbed her eye after touching the table).

Having gone through two reactions with my son, the one where he vomitted was the least severe. He started vomitting 10 minutes after ingestion and continued doing so for 20-30 minutes. I viewed the vomitting as a positive because his little system was trying its best to expel the allegen.

Has anyone had any experience where both vomitting and anaphylaxsis occured? From my son's experience, the first time he was exposed he didn't vomit but went into anaphylactic shock. The second exposure he vomitted but avoided anaphylaxsis. I wonder if vomitting prevents anaphylaxis.

I regret to say that I have both vomiting and anaphylaxis. I finally had to start carrying an epi about 10 years ago, when the severity of the reaction made getting to emergency a doubtful proposition.

My son has 3 reactions to date, and all quite
different. The first time he went into anapahalactic shock but no vomiting, hives or
swelling. We know that he was in the same room a an open jar of peanut butter but to our knowledge he didn't eat any. The second time he age one bite of a chocolate bar and after about 20 minutes he threw up twice. At that point we gave him some Benadryl (on the advice of the ER doctor) and then we thought
he was fine. It wasn't until about 3 hours later that his breathing was affected and at that time we used the Epipen and rushed him to the hospital. He was fine immediately after the injection.
The third time he threw up four different times over a period of about 4 hours but no other symptoms.
I think that vomiting may be very helpful in reducing the chance of anaphalaxis (I don't know if this if a fact or not, just my guess).
I do know for a fact though that kids need to be watched for several hours after exposure as there can be a delayed reaction, as with his second experience. I thank God that I had let my son fall asleep with me while I was watching TV, or I don't know what might have happened!

My son's first (2 1/2 yrs.) and so far only reaction caused him to vomit immediately. In fact, I thought he was choking. Within seconds of one tiny bite of peanut butter on toast he vomited, turned red in face, hives all within a minute or two. Then came the grey/blue lips and circles under his eyes - combined all of this was within 3 to 5 minutes. Thank goodness I'd had first aid and immediately connected all these reactions to the peanut butter and was on 911 before the breathing problem started. I have only been reading the peanutallergy.com chats for one week and I have learned so much with real-life experiences from everyone. Like I wrote, my son has only had one reaction. I am sure even as diligent as I am there will be more.

My daughter's only experience was a piece of candy that went in her mouth about a second before I grabbed it out. She vomited immediately for about 10 minutes and had hives all over her body. I gave her Benadryl on the advice of my pediatrician. I wasn't aware how long these attacks can last so I thought she was fine and luckily she was. But I will never let her sleep alone if there is ever another episode. I am glad everyone shares their stories so we can all learn. I sometimes wonder at how lucky I have been. It seems that you never know when or how bad these attacks are going to be. I just pray I am careful enough to never have another one. Thanks for all the info. P.S I now carry 2 epis with me at all times just in case.

Oh wow... this is very scary indeed. When my son had his initial reaction, we gave him benadryl and he got sleepy, so we put him to bed. Had I known about delayed reactions, I would have put him in bed with us. Thank goodness he was okay. And I know to watch him closely afterwards now.

An update on the vomiting issue...

We had an appt with our son's allergist late last week. I asked about vomiting, thinking it was probably a good sign because the body was ridding itself of the allergen. The allergist said that it's the stomach trying to deal with all the histamine that has been produced after being exposed to peanuts. So it's not a good thing to happen -- that's why vomiting is considered anaphylatic (sp?) because the allergy is affecting a major organ.

If anyone has additional information, let us know.

Hi Tracy. My daughter also vomited after her first reaction. When we saw our allergist a couple of weeks ago she diagnosed her as peanut anaphylactic. Again I wondered why but you don't always ask the right questions at the right time. In hindsight I could ask her a million more things, but I think you answered my question on why she considered her anaphylactic. I always thought it just meant you were having trouble breathing. Oh my god I just keep wondering how lucky I was that night that nothing worse happened. I didn;t even have an epi-pen then. Thanks for the info Tracy

Hi Tracy:

Thanks for your detailed report from your visit with the allergist. I had wondered whether my son's second response was better because he vomitted so much rather the hives, swelling, and coughing. Now I know it was probably more on par.

I went to buy him a snack this morning and my 4yo says, "Mom, make sure there's no peanuts in it." I swear he'd be more vigilant than I if only he could read. :-)

My 4 year old daughter is allergic to peanut products and eggs. Does anyone know whether an allergy reaction to peanuts can be just the throwing up - no rash or breathing problems. How about any info on throwing up and a slight fever? Any info on a slight fever during an allergy attack?

My son vomited almost immediately after eating a peanut cracker. My allergist (from Johns Hopkins) said that this was positive as much of the allergen was expelled immediately. He said there are study's showing a correlation between severity and amount consumed. However, he said that one symptom could be swelling of the stomach and then vomiting which would not be positive.

My interpretation of our discussion is this:
If you vomit immediately much of the allergen is expelled (positive). If you vomit after a period of time then it's probably a systemic reaction (negative).

My daughter, age 4, has had only two bad reactions to peanut butter. The first one was vommiting and difficult breathing, but she did not get any hives or swelling. Her second reaction, her lower face got all red then her face puffed up big time. So she had two reactions each totally different. The first one, which didn't change her outward appearance, was the more dangerous one.

my son had a touch of chickpeas (it was visible to the naked eye, but it wouldn't qualify as a bite, it was *very* small) by stealing a carrot from my plate.
Vomiting was *immediate* !!!

My 2 yr old kept breaking out in hives and i couldn't understand why. The doctor told me that it just happens sometimes and he told me to give him benadryl (which we later found out he was red food dye #40 A) this went on for another week. Everyday i would make my older son lunch. peanut butter on crackers. every day he would break out and start cough. The dr. told me that what my so had was bug bites. I drove the poor exterminator crazy. I called the doctor asked for an allergist. Thank god I did. He ended up testing for food allergies. peanuts was sever. i carry epi pens with me at all times. The worst reaction that he ever had was at a resterant. My cousin was retiring and the entire family went out to eat. I told them that my son had a sever peanut allergy. They were accomitating or so i thought. My neice gave him a bite of a fried cheese stick. He started to get very tired and about 1/2 an hour later he was vomiting so bad. He ended up in the hospital overnight. I didn't know that vomiting was a sign.

mamakat, you have described my dd's past reactions to a "t".

What a shame that your son's original doctor was so clueless. I am so glad you managed to get a competent opinion, after all.

yesterday driving home from the zoo with my husband, my son threw up. he said the car smelled funny. he had a strawberry nutrigrain bar which he had before. after that he had juice, started choking and threw up. the only other things he had that day were home made funnel cake (i wonder if it was too greasy), juice, milk, and his new gummi vitamin. he has been taking these for about a week. they have coconut oil and iodine in them. im going to call allergist tomorrow to see if he needs further testing because he has only ever thrown up after eating nuts. my husband gave him benadryl and he was fine. when he ate nuts he didnt even get benadryl and was always fine after throwing up.

Could be a strawberry allergy?

Don't forget, you can develop an allergy at any time.

I have a peanut allergy. I was fine when I was a child but now I'm 32 and it seems to have gotten worse... I have a really strange delayed reaction.. Last year I went to Texas Roadhouse (where there are peanuts everywhere..) I didn't eat any but sure that just being exposed to it caused my issues. About 16 hours later I started vomiting profusely and continued to do so for like 8 hours. I didn't realize that was it at first.. But every time I eat a nut of any kind the same thing happens to me.. I'm wondering why the delayed reaction.. I'm an RN myself and not sure why.. Haha.. but I know if I avoid nuts I never have any issues like this.

The first clue that I have eaten a peanut is an itchy throat feeling. My allergic reactions to peanuts have always included vomiting. Ingest, wait a few minutes and throw up. The only way I have short circuited this process is to quickly drink a full glass of cold milk right away before the peanut gets much past my mouth, which I suppose coats the digestive tract, preventing the reaction. Now a days I also carry an epipen and benedryl tablets with me, but I haven't needed to use them for a peanut reaction...yet.
