If a prescription is missing a patient identification number, what is the most appropriate action?

• A. The most appropriate course is to contact the prescriber
• B. Accept the prescription and fill it as is
• C. Ask the patient to call back later
• D. Use the last patient ID on file

Answer: (A)

When essential patient identifiers are missing from a prescription, the pharmacist must verify the patient’s identity and ensure the prescription data matches the correct person before dispensing. The best action is to contact the prescriber to obtain or confirm the missing patient identification information. This keeps dispensing accurate, prevents potential misidentification or medication errors, and upholds professional and safety standards. Accepting the prescription as is, asking the patient to call back later, or using a last ID on file could lead to dispensing to the wrong patient and breach privacy or liability concerns; these approaches do not reliably resolve the missing information. Document the contact with the prescriber and obtain the necessary details before proceeding.
