Which of these is an example of a clinical abuse or misuse detected during Drug Utilization Review?

In the context of Drug Utilization Review (DUR), inappropriate dosage is recognized as a clinical abuse or misuse issue. DUR is a process intended to ensure that medications are used appropriately and safely, focusing on relevant parameters such as dosage, drug interactions, and adherence to treatment guidelines.

When a patient receives medication at an inappropriate dosage, whether it is too high or too low, it can lead to adverse effects or inadequate treatment, making this a critical concern in clinical settings. Monitoring for proper dosing is essential to ensure that patients achieve the intended therapeutic outcomes while minimizing the risk of side effects or complications.

While the other options—incorrect storage conditions, expired medications, and unlabeled medications—are significant issues related to medication safety and efficacy, they do not directly pertain to the clinical use of drugs or how they are prescribed and administered to patients. Instead, these pertain more to the physical handling and management of medications rather than clinical appropriateness. Thus, inappropriate dosage stands out as the primary example of clinical abuse or misuse identified through a DUR.
