Which statement best describes a prospective DUR?

• A. Review conducted weeks after dispensing
• B. Review during dispensing
• C. Review during patient counseling
• D. Review conducted at the time of dispensing

Answer: (D)

A prospective DUR is a pre-dispensing review that looks for potential drug therapy problems before the patient receives the medication. It’s done at the moment the medication is being prepared for dispensing, so issues such as drug interactions, contraindications, allergies, dosing problems, or duplications can be identified and addressed right away.

That’s why the best description is the review conducted at the time of dispensing — it captures and prevents problems before the patient is exposed to the drug. Reviews conducted weeks after dispensing are retrospective, and reviewing during patient counseling is part of counseling itself but not the formal pre-dispensing DUR. Review during dispensing is similar in timing, but the standard phrasing emphasizes the exact moment the drug is dispensed.
