Other medications associated with green urine may contain phenol groups
and include promethazine, thymol, cimetidine,
and propofol. The
mechanism of action appears to be caused by phenol's conjugation by the liver and subsequent excretion by the kidneys. The strength of the green seems to be dose related. Some nonphenol drugs noted to produce green urine are metoclopramide, amitriptyline, and indomethacin.
