I have a few years ago and after 2 visits in 2 days to the ER I found out that some newer antisthimines derive from it. They say it's something like 2 nd series type thing. It's very hard to trace anything not obviously containing Benadryl IE Tylenol Pm etc. I am terrified now to take anything without being certain that it has no possible link to that. I actually got so bad I went into anaphylactic shock the first time this week to the ER and today had to use the Epipen they prescribed me because my lips swelled 3 times their normal size. This was in conjunction with the huge whelts all over my body.
Can ANYONE relate?
Has anyone else been diagnosed as allergic to Benadryl?
