[|Human|] dad has end stage pancreatic cancer..urine now turned orange. he is on rifampin fro itching (bilirubin), but has been on it for weeks. Is the urine orange because the tumor blocking the bile duct? or maybe from chronic rifampin use? Just wondering if this is a sign of the end nearing or if it was from med
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Orange color of urine is due to chronic use of rifampicin.  Bile duct obstruction may be a cause. It causes obstructive jaundice and high conjugated bilirubin excreted via urine causing orange color.  You should go for ultrasound abdomen or ct scan abdomen to rule out bile duct obstruction. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
