just tell them that you are allergic to fluoroquinolones period. that is what i do. i had a reaction to avelox. this was after i already had pn.
i had a similiar screwup a few years ago, i am allergic to ampicillin and have it in my records both doctors and pharmacy, and i was precscribed augmenten and didnt realize it was in the same class, they should have though. i had rashes all over the thickness of which i have never seen before. this allergy went back to 1977, back then after they gave me ampicillin, i looked like joe frazier after the ali fight.
