Here is what the Rx symbol means in medical prescriptions


The phenomenon of ubiquitous prescription drugs (retail sales in recent years have topped $200 billion in the U.S. alone) is a relatively new experience in human history. However, its common abbreviation, , has deep roots in the relatively distant (and some even claim ancient) past.

Recipe for Wellness

While there are a few commonly put forth explanations as to how we ended up with the  symbol. it’s generally thought that it has medieval roots as an abbreviation for a form of the Late Latin word “recipere” meaning “to take.” The imperative form of this word, “recipe,”  meant “take…” as in, “take two and call me in the morning.”

By the 1580s, the word “recipe” had been slightly modified in Middle French to récipé, and had come to mean “medical prescription.” In fact, this meaning of the word prevailed until the mid-1700s, when it was also applied to food preparation.

Regardless, when giving a prescription, physicians typically began their directive with the command “recipe,” which ultimately was abbreviated to . Other common abbreviations used in the medical field that also included an “x” were things like “dx” (diagnosis), “sx” (signs and symptoms), and “hx” (history).

Prayer for Well-Being
