I have been allergic to neosporin for over 10years after using for 40/50yrs?? forever I'm 69..Bacitracin does great for me. I have always been allergic to metal/rubber/latex all my life but was taken to hosp for chest pain..because of aortic replacementbmitral repair/afib since 3/ in hospital for 9 days when I came.up with the dumbest idea. Since I could pick my own meals, I ordered oj, banana, toast for breakfast, lunch was tea, lg fruit cup and ham sandwich/ dinner was large salad and banana smoothie...etc for 8 of the days..doctors couldn't find anything but holter went nuts 3 times a day... 3 times a day an hour after meals. They.came rushing in to see if I was in distress! Nope watching tv..I told them, i'd bet money on the banana cuz I had the midnite nurse do some google work the nite before and she had found the rubber, latex and banana , was all connected . Discharged no bananas except once a year. Never had another prob since then. Everyone laughs and says no such thing. And no dr has ever listed it as allergic..so I write it in.....Question since I have never had life threatening reaction to any of my allergies, only the neosporin ..which a dab on an ingrown toenail went from no visible infection at 9pm one nite went to a big marble size green ball full of pus in about 5 minutes and by 10 min my entire foot couldn't get into my husbands size 13 shoe. I wear 7 female. Are all allergies considered worthy of telling hosp personnel?
