Etymology: "Floxed" is a term from molecular biology that turned into patient slang. The verb "flox" comes from "flanked by loxP", where "loxP" names a short DNA sequence recognised by the Cre enzyme, which cuts out whatever lies between two such sites. Researchers would say a gene was "floxed" when they had engineered loxP sites on either side of it, so it could be deleted in selected cells or tissues on demand. The word is therefore a shorthand built from laboratory vocabulary rather than an ordinary English coinage. Patients took the term from the lab and applied it to their own bodies. The "flox" in the sense of harm from antibiotics is a separate, later usage: people describing fluoroquinolone injuries, such as tendon rupture and nerve damage, used "floxed" as a shorthand for being damaged by those drugs. The source's other proposed origin, a blend of "fluorine" and "liquid oxygen", belongs to an unrelated older sense of "flox" and does not explain the modern term, so it is not relevant here.
