Drugs and Urine Discoloration

The color of the urine can tell us many bits of information about our health conditions and can tell us even if we are taking some medications, based on their capacity to discolor it. Urine discoloration may be a side effect of rifampicin, which can turn urine red. Ferrous salts, levodopa-carbidopa, and proteus infections can turn urine black. Warfarin, heparin, doxorubicin, and beet can turn urine pink. Amitriptyline, cimetidine, and methylene blue can turn urine blue. Metronidazole, nitrofurantoine, and senna can turn urine brown. Phenazopyridine and riboflavin can turn urine orange. Propofol, asparagus, and pseudomonas infections can turn urine green.
