Propofol has been reported to cause discolouration of urine and hair.
A case of green discolouration of the liver is reported in a 56-year-o
ld man after long-term sedation with propofol in the intensive care un
it. After discontinuation of propofol the discolouration of the liver
disappeared. This phenomenon is due to metabolism of propofol which ma
y lead to a phenolic green chromophore which is conjugated in the live
r and excreted in the urine.
