My husband recently went through a heart cath in which they placed 8 stents. He has been on a variety of meds before and since, including Plavix, asprin, etc. His heart cath was two weeks ago. Yesterday, he told me his urine was "florescent yellow" in color and he wondered if any of the drugs could have caused it. I told him I didn't think so, since he had been on them for a while.

Any idea what it could be? He does not take any type of vitamin or mineral supplements.
