What does Rx have anything to do with a pharmacy?

"Rx" is an abbreviation of the Latin "recipe", the imperative form of "recipere" which means "take thus". A prescription is a physician's directive to the pharmacist with instructions on preparing and administering medicine or other therapy.

There are two possible answers, the first being more probable.

1. Rx is latin for recipe, or "to take," So when physicians write that on the prescription, the pharmacists know that it is indeed a prescription.

2. Rx suggests that it's a form of the astrological symbol for the Roman god Jupiter, written on prescriptions to get the god's blessing.

According to the Pharmaceutical Handbook (nineteenth edition, 1980), the Latin abbreviation Rx is completed by some statement such as "fiat mistura," which means "let a mixture be made," sometimes abbreviated to f. m. or ft. mist. or fait mist.). Pharmacists required a knowledge of compounding until recently. In 1920, 80% of prescriptions were compounds mixed in the shop. In the 1940s the number of prescriptions requiring compounding had declined to 26%, and then to 1% or less in 1971.
