Hello,



Pyridium or Phenazopyridine Hydrochloride has properties of an azo dye.It is coloring your semen. Your ejaculate is comprised of fluids which are stored in small sacs called the seminal vesicles. So the color can accumulate in the seminal fluid and show up even when the drug is stopped.So pls don’t worry as it is due to this drug.But pls see that you don’t take pyridium for too long(maximum of two –three days) as it can cause other side effects.



Hope it helps.Take care and pls do keep me posted if you have any additional queries.Kind regards.
