Azo Standard - PhenazopyridineBy Jean Solis from Houston, TX on January 10, 2007 Category: Phenazopyridine hydrochloride I am beginning to have a urinary tract infection. Until I get to the doctor, I am taking Azo Standard for the discomfort. I am due to have a urine drug screen today or tomorrow. Will the Azo Standard affect the outcome of the drug screen - possibly a false positive for anything that could cause me problems? |
