Prescription

 

written instructions from a physician to a pharmacy for the preparation and issuance of a medicine and also containing directions on how to administer the medicine. Prescriptions are written according to definite forms and rules.

A prescription is a legal document, since it makes it possible to verify whether a medicine has been prepared correctly.
