What is Rx? Definition and usage

LAST UPDATE: July 29th, 2017

Definition

‘Rx’ is an abbreviation of “Received” or “Received transmission” when used in the context of fax machines and office equipment.

The Merriam-Webster dictionary defines “Rx” as a “prescription.” The Oxford dictionaries define Rx as “a doctor’s prescription.” Both of these definitions are the more popular use of “Rx,” but do not apply to the context it is used in for fax transmissions.

Usage

In the context of fax, it is often used for reporting and logging. “Rx reports” refer to “received fax reports.”

History of the term

The format of the abbreviation is likely derived from “tx” (an abbreviation of ‘transmission’).

Other uses

The most popular use of “Rx” is in medicine as an abbreviation for “prescription.” The “Rx” stands for “take,” literally an abbreviation of the Latin word “recipe” which means “take.” The symbol ℞ is often used in this context.
