When I was a child I was given cough medicine with Codeine in it. I had a rather SEVERE reaction to it. How severe? My parents had to perform CPR on me. So that should tell you. Anyway, when I was pregnant, on my first prenatal visit the Doctor asked me about why I had it marked that I was allergic to Codeine. I explained my allergic reaction as a child and he looked at me and said, "Well, you've most likely out-grown that allergy by now." I was like, "I don't want to try! Even if you've got a crash cart near-by!" It's not like I said that I got the hives or something like that. I told him that my heart stopped beating and he brushed it off. So my question is this, "Has anyone here ever OUT-GROWN such a severe allergy?"
