â is a symbol meaning prescription. It is sometimes transliterated as R x  or just Rx. This symbol originated in medieval manuscripts as an abbreviation of the Late Latin verb recipe, the imperative form of recipere, to take or take thus.rescription may also be used as a short form for prescription drugs to distinguish from over-the-counter drugs. In reference to the entire system of controlling drug distribution (as opposed to illicit drugs), prescription is often used as a metaphor for healthy directions from a prescribing medical practitioner.
Barrow boy. 1 vote Vote for this answer. On a prescription the symbol Rx (or R) stands for the word Recipe, meaning (in Latin) 'to take.'. Now in pharmacological contexts like catalogs, the symbol Rx indicates that a drug or medicine is not free to buy, but has to be prescribed by a certified physician.he traditional RX symbol cannot be represented on a typewriter keyboard. It consists of an R and an X which are merged to resemble an R with an extension of the right leg of the R with a stroke across it (I hope that makes sense).
