Opaz: I've had cystitis issues ever since my dance with bladder cancer began. I've had three or four biopsy sessions that came back negative for cancer because my URO wanted to know whether the erythema he was seeing was CIS. I had to stop BCG after two instillations because a bladder bleed that had to be cauterized. I pass some calcified material occasionally, and can't hold too much volume, which can make urgency an issue. I've taken AZO, but have not found it to do much for me, except to turn my piss bright orange. I think I've taken it for a day beyond the 2-day recommendation. Hope it will work for you. The box I have says ask your doctor if you're going to take it more than 2 days. And I just noticed it also says, the active ingredient is "known to the State of California to cause cancer."
