Which information is NOT required on the dispensing record of controlled substances?

The requirement for a dispensing record of controlled substances is guided by statutory regulations aimed at ensuring proper tracking and accountability in the handling of these substances. While records must include essential details to maintain compliance, certain information may not be mandated.

The name of the substance, the name of the animal owner, and the amount of substance dispensed are all critical pieces of information that help track the prescription and dispensation of controlled substances effectively. The identification of the substance ensures that the correct medication is provided, while the owner's name links the medication to a specific patient and their owner, which is essential for maintaining medical records.

The invoice number, however, while useful for inventory and business purposes, is not a statutory requirement for the dispensing record itself. It does not directly pertain to the medical information necessary for tracking the patient's treatment with controlled substances. Consequently, it is the least essential among the information listed with regard to legal compliance for dispensing records.
