What causes orange urine?

Orange urine: This is commonly seen after women take an over-the-counter bladder spasm medicine called pyridium (phenazopyridine) for UTI symptoms. Some high-dose vitamins or supplements could do it too, or if you eat excessive amounts of foods with beta-carotene (like carrots). Or, if you are dehydrated, that makes your urine more concentrated and it appears amber or orange.

Orange urine: Possible reasons for orange urine: Eating lots of foods high in beta carotene such as carrots, vitamin B2 or C or food dye (Tartrazine – yellow 5). May be due to dehydration or problems with liver/ bile duct. Medications: Pyridium, laxatives, Rifampin, warfarin, Azulfidine & some chemotherapy medications.
