akroeze 5 Posted August 8, 2009 Share Posted August 8, 2009 Has anyone heard of someone being allergic to Diphenhydramine? I had an allergic reaction case yesterday that became anaphylactic immediately after I administered IV Benadryl. I know the far more likely case is that that is coincidence and the patient just chose that moment to go anaphylactic from her bee sting, but just wondering if it is possible?

I think it's just coincidence that it happened at the same time you gave her benadryl. Quote Link to post Share on other sites

Kaisu 198 Posted August 8, 2009 Share Posted August 8, 2009 There is a rare adverse reaction to benadryl (not the dye). It is characterized by seizures. Unless your patient went into seizures, I would say the development of anaphylaxis was coincidental to the administration of benadryl and not an effect. Quote Link to post Share on other sites
Chief1C 330 Posted August 8, 2009 Share Posted August 8, 2009 That's why they make the dye free Children's Benadryl Quote Link to post Share on other sites
fireflymedic 76 Posted August 8, 2009 Share Posted August 8, 2009 I had a patient once that stated he was allergic to Benadryl - fortunately I wasn't treating him for an allergic reaction nor did he have one to anything I gave so I was safe. However, there would have been a definite pucker factor had I needed to give it and been unable too ! Sorry you ended up in this situation ! Quote Link to post Share on other sites

Not sure if mine was due to the benadryl or the dye in the benadryl but either way it does happen and from what i was told its not well. I dont remember much of what happened so I cant tell you that part. Quote Link to post Share on other sites

I dont remember much of what happened so I cant tell you that part. Sure that wasn't the scotch? I have only heard of allergy to the dye. But I guess we could get the dye free give it to itku2er and see what happens. Trust me I'm a Paradork. Quote Link to post Share on other sites
akroeze 5 Posted August 8, 2009 Author Share Posted August 8, 2009 Surely there isn't any dye in the intravenous formulation? Quote Link to post Share on other sites
Kiwiology 195 Posted August 8, 2009 Share Posted August 8, 2009 Very interesting post. Just read the blong and I'll chip in that we use nebulized adrenaline and salbuatmol for angioedema and bronchospasam secondary to anaphylaxis. I'm told we can't mix them in the same nebulizer bowl however. Quote Link to post Share on other sites
