Can antihistamines trigger hives?

Question:

In the last year I have had a problem with hives. I have gone to the allergist and he put me on several antihistamines. They took care of the hives when I was on them but if I missed a dose they would be really bad. I made the decision to stop taking them a few months ago. My hives got a lot better and I hardly had any breakouts. During the time when I wasn't regularly taking the antihistamines I experienced at one point an allergy not related to hives (sneezing and runny nose) and took an antihistamine to help with that. All of the sudden a couple of days later I had hives again. Could antihistamines actually trigger hives which is opposite of what they should do?

Answers:
its very possible. you need to find out if you are allergic to the antihistamines. consult your doctor.

well you can be allergic to anything i guess, so it is possible, i took alfalfa pills to cure sinus trouble, and they worked but they gave me hives and i was a mess for a month, thankfully i can take the antihistamines.
