What type of documentation must be maintained by a pharmacist when dispensing a controlled substance?

When dispensing a controlled substance, a pharmacist is required to maintain a record book, which serves as an official documentation of all controlled substance transactions. This record book is essential for tracking the movement of controlled substances and ensuring compliance with federal and state laws. It must detail the names and quantities of the drugs dispensed, the names of the patients receiving them, and the prescribing healthcare provider. This documentation is crucial for maintaining accountability and transparency in the handling of these medications, which have a higher potential for abuse and dependence.

Other documentation types, such as insurance policies, employee records, or patient medical histories, do not fulfill the specific regulatory requirements mandated for controlled substances. While patient medical history may be relevant to the overall care provided to patients, it is not a formal record of controlled substance transactions required by law for accountability and reporting purposes.
