What is the role of a written prescription?

The role of a written prescription primarily serves as an instruction for a pharmacist to dispense medications accurately and appropriately. It contains critical information such as the medication name, dosage, quantity, and instructions for usage that the pharmacist must follow to ensure the patient receives the correct medication. Additionally, the prescription ensures that the medication is dispensed in accordance with the healthcare provider's professional judgment, maintaining safety and efficacy in patient care.

While providing directions for patient care may be involved indirectly, the primary function of the prescription is focused on the interaction between the prescriber and the pharmacist. Therefore, it is designed specifically for the pharmacist's use in fulfilling the patient's medication needs accurately.
