A white crystalline substance that was once used to relieve pain and reduce fever, but is no longer used due to harmful side effects.
Phenacetin was commonly prescribed in the past, but it has been banned in many countries due to safety concerns.
Phenacetin is formed from "phen-" (from Greek "phaino", meaning to show or to appear) and "acetin" (derived from acetic acid, which is a component of vinegar). The word refers to a compound that shows or appears to have analgesic properties, as it was used as a pain reliever.
Think of 'phen-' meaning to 'show' or 'appear' and 'acetin' relating to a component of vinegar, which helps you remember that phenacetin is a compound that appears to relieve pain.
