answer:First, whenever you have a skin reaction to a medicine that is a serious reaction and almost always it is recommended to cease taking the drug. The doctor should switch you immediately to another medication. If your skin reaction continues to get more severe or if the skin is peeling seek medical attention immediately. It is very very important you remember this drug and always list it as an allergy. Was the drug a sulfa drug? Bactrim maybe? A significant percentage of the population is allergic to sulfa drugs. Second, it is extremely unlikely a new antibiotic will give you a bad reaction. The new drug would likely be from a totally different class of antibiotics. Someone who is allergic to Penicillin might be able to take Tetracycline with no problem or Cipro with no problem. They are all antibiotics, but each one is a different drug class. Think of it like killing an ant by stepping on it or with bug spray. Very different ways to do it, same result. If you want you can tell us the different drugs and we can help you look them up and provide links so you feel better about taking them, but I think you need to take the antibiotics. It sounds like you took enough meds to get the bacteria numbers low enough to get rid of your symptoms, but not rid of the bacteria completely so when you stopped taking the drugs they just multiplied again and so within a few days of stopping you are infected again. For future info, if you had switched immediately to the other drug you probably would have just needed a few more days, but I understand why you were reluctant. Note: I am not a doctor.
