Ahh. I've been wondering the exact same question. A friend of mine and her boyfriend is on felony probation and they both take AZO's. She said take them, and then you will be pissing orange for liek the first 10 pisses. AFter that your clean. I asked her if it really did work and they both told me that it did. So.. I just want to know if it works as well.

P.s - Its for a urinary track infection. .
