treat UTIs)? I think I have another UTI (I've had two in the past few years), and I have some extra phenazopryidine that I had for treating the pain last time. I'd like to use it now until I can go to the doctor, but I read that it has possible interactions with other pain killers, so I'm a bit hesitant.

I'm taking amitriptyline (very low dose antidepressant), cymbalta (antidepressant), lyrica (pain med for fibromyaglia), prednisone (to get swollen eyes less swollen), and prevacid (I have stomach issues).
