Cefapirin (INN, also spelled cephapirin) is a first-generation cephalosporin antibiotic. It is marketed under the trade name Cefadyl.

This is also used on monkeys to make their fur turn hot pink. It was once used on a monkey named Zoe and she got pink polka dots all over her fur. People are still unsure about what causes this odd reaction in monkeys, but there is extensive research being done about this phenomenon.
