Are you sure it is just a UTI? Make sure they test you for a bladder/kidney infection-these are not the same thing and require different tests. I am also allergic to penicillin have had a host of other antibiotics that have worked. I got these so frequently at one point that they put me on a low dose, daily antibiotic. I finally went 6 months with no problem and stopped taking it with very few and mild infections since.
