Which piece of information is NOT required on a prescription drug order?

In the context of prescription drug orders, certain pieces of information are essential to ensure the safe and accurate dispensing of medications. Among the listed options, the patient's full name, drug strength, and prescriber’s license number are all required for a valid prescription.

The patient’s full name is necessary to identify who the medication is intended for and to avoid confusion with other patients. The drug strength is important to ensure the correct dosage is administered. The prescriber’s license number verifies the legitimacy of the prescriber and confirms that they are authorized to prescribe medications.

However, while knowing a patient's age can be beneficial in some contexts, it is not universally required on a prescription. The patient's full name and the specific details about the medication take precedence over the age in the legal requirements for a prescription in South Carolina. This understanding highlights the crucial aspects of prescription requirements and the focus on safety and identification in medication dispensing.
