I have a son that is allergic to antihistamines. It began with dimetab when he was an infant which resulted in an all over rash...Was told it was a reaction to either the dimetab or his innoculation of mmr. As years went by every year he would have a cold and we would give him an antihistimine and it took years for the doctors to discover it was the antihistamines. As he got older the results were much worse. Different areas of his body would be bright red (appearing sun burned) his joints would swell and be bright red and then everywhere there was the sunburned appearance, the skin would peel. He would be down for weeks. We had no insurance but continued to take him to the family dr. who would try to figure it out. Finally, thinking he would be crippled because of the swelling of his joints, knees especially, we had help from Shriners. They were the ones that discovered the antihistimine allergy. Ever since, no problems, except when he gets a cold or sinus, he has to wait it out......
I know this is late but I was wondering how she was doing as I had a reaction to anti histimines, Hydroxyzine,a week in to taking it, I had a lot of stomach pain almost akin to a gall bladder attack and I have chronic Hives which is what it was prescribed for. I am now doing my own research on the Internet and finding Natural Remedys to help myself as truly noone where I live knows much about Allergies or anything else unless its to do with Botox!!
Yeah, a similar thing happened to me yesterday. For some reason I was having sneezing fits pretty bad yesterday, so I took 50mg or Diphenhydramine Hydrochloride, which is a generic antihistamine. The sneezing stopped, I got drowsy (this always happens when I take antihistamine), and within 30 minutes I was beginning to break out in hives.
I usually only take 25mg to combat allergies, but I just wasn't in a conciliatory mood yesterday, so I took 50mg. Looks like my body reacted by doing the opposite of what the medicine was trying to get it to.
Hives usually fade after a few days, I'm just going to sit tight and let my body readjust.
