Synonym discussion
Sense: noun/1
All four words point to a doctor's written instruction for medicine, but they live in different settings. 'Prescription' is the neutral, full word used in clinics, news, and packaging — safe in any register. 'Script' is the casual short form patients and pharmacy staff use among themselves, as in 'I need to refill my script'; it sounds friendly but slightly informal in writing. 'Order', as in 'doctor's order', is much broader and can cover any medical instruction, including tests or rest, not just medicine. 'Rx' is the symbol printed on the slip and on drug packaging; it functions as a written abbreviation rather than a spoken word, so you would write 'Rx only' on a label, but say 'prescription only' when speaking. When in doubt, choose 'prescription'.

Etymology
From Latin 'praescriptio', meaning a written order or rule set down in advance, built from 'prae-' ('before') and 'scribere' ('to write'). The word entered English through Old French in the late 1300s, first carrying the general legal sense of a fixed rule. The medical meaning — a doctor's written order for medicine — grew in the 1500s, as written drug instructions became standard practice. The figurative use, meaning a recommended plan, came later by extension.
