Hi i am new here. I have a general question that maybe someone has been through before. I have had a UTI for about two weeks now. I am VERY sensitive to antibiotics, and can usually only tolorate low dose amoxicillian. But my doctor states that my culture is resistant to this antibiotic so i will need to take a different one. I tried Macrobid last friday and had a terrible reaction, as my IBS-D is in full flare up right now. I have taken Mannomax, and cranberry pills with no luck, it is not a severe UTI it is very low in the count. So, does anyone know what antibiotic would be least aggravating on my stomach and has helped with UTI?Please help!!
