Which of the following is part of the required information for drug dispensation reporting?

In the context of drug dispensation reporting, one of the crucial pieces of information is the date the prescription was written. This is important because it helps establish the timeline of when the medication was authorized for the patient, which is essential for tracking the medication's usage and ensuring that the prescription is still valid when dispensed. It also plays a role in monitoring compliance with treatment plans and assessing patient outcomes over time.

The other options may provide useful information for different aspects of pharmacy practice but do not fulfill the specific requirements for drug dispensation reporting as mandated by regulatory entities. While the cost of the medication might be relevant in terms of billing or insurance purposes, and the pharmacy's location is important for identifying where the medication was dispensed, they are not typically required elements for the report itself. Frequency of refills is relevant but not as fundamental as the date prescribed, which is critical for the integrity and legality of the dispensing process.
