Which part of the prescription provides directions to the patient?

The part of the prescription that provides directions to the patient is referred to as the "Signa." This term, derived from Latin, literally means "mark" or "sign." In the context of a prescription, it conveys the specific instructions for the patient on how to take the medication, including dosage, frequency, and any additional directions necessary for proper use. This information is crucial for the safe and effective administration of the medication by the patient.

In contrast, the other components of a prescription serve different purposes. The inscription contains the name and dosage of the medication prescribed. The subscription is used to provide directions to the pharmacist on how to prepare the medication, indicating the quantity to be dispensed. The superscription is the part of the prescription that typically includes the symbol "Rx," which denotes the prescription itself. Understanding the distinct roles of each part helps ensure clarity in both dispensing and patient adherence to medication regimens.
