Green coloured urine is atypical as it usually signifies the presence of an 
exogenous substance. Several substances in literature have been associated with 
green urine including propofol, biliverdin, metoclopramide, methylene blue, 
indigo blue, amitriptyline, methocarbamol, indomethacin, promethazine, 
cimetidine and food colourings. We present here a case of middleaged man who 
presented to our ER with altered mental status and green coloured urine with 
positive urine toxicology reports for benzodiazepine.
