Which of the following tasks is NOT permitted for a pharmacy technician?

Conducting a prospective drug use review involves evaluating a patient's medication regimen before a prescription is dispensed, assessing for potential drug interactions, allergies, and ensuring the appropriateness of therapy. This task requires clinical judgment and a deep understanding of pharmacotherapy, which is beyond the scope of practice for pharmacy technicians.

In contrast, pharmacy technicians can assist with inventory management, helping to ensure medications are in stock and organized, and they may also participate in the filling process of prescriptions under the supervision of a licensed pharmacist. They are allowed to communicate with prescribers about new oral prescriptions, usually under the guidance of a pharmacist. However, they cannot provide final verification of filled prescriptions, as this is reserved for licensed pharmacists who have the legal authority to make final checks on the appropriateness and accuracy of the medication for the patient. Thus, the correct choice highlights a task that pharmacy technicians are not authorized to perform, reinforcing the regulatory framework that delineates the roles of pharmacists and pharmacy technicians.
