i dont need someone to tell me to drink cranberry juice and water that is all i have been doing is drinking water, but my body isnt reacting to the antibiotics that they have perscribed me.i am just looking up the different antibiotics that they can give me to see which one i think might help so i can suggest it to my dr . ive had this same infection for almost 4 monthes now. and im tired of the pain.and im sure anyone whose has a serious bladder infection knows where im coming from

I am allergic to Sulpha drugs ( the ones you listed)
The Dr. usually puts me on a heavy dose of Doxyclycline
