Hi. I am allergic to Penicillin, Sulfa, sulfur, sulfates, seems like anything that starts with sul. I have a lot of trouble with antibiotics. Just wondering which antibiotics does not contain any form of sulfa or any form of Penicillin. My doctors seem to have a problem finding antibiotics for me to take. I usually have a reaction to a lot, most. I research and usually I can find some kind of sulfur or penicillin in it.
