The Lesser Antilles (also known as the Caribbees) [citation needed] are a group of islands in the Caribbean Sea.

The islands form the eastern boundary of the Caribbean Sea with the Atlantic Ocean.

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. Curiously, propofol also is associated with pink and white urine.
