<<Disclaimer: Verify this information before applying it to your situation.>> I'm having gall bladder surgery. Have become sensitive to wheat and corn starch and sometimes to dairy. And I've had scary reactions to epenephrine during dental work. What should I watch out for. I have told the surgeon that I have reactions to epenephrine -- he said I should be cautious about saying I'm allergic to it. He gave me the usual routine about it's the same thing we produce when scared or shocked (adrenaline). I told him if he had ever had the reaction I had that he would never repeat that to his patients again. Anyway -- does the dextrose in the drip solutions come from corn syrup. He assured me they would never put something in them that people could have adverse reactions to and that the dextrose is chemical. I must more more -- I can't just take his word for it. How do I find out and has anyone had similar questions answered before surgery. Thanks Anna
