What is a necessary piece of information that must be recorded when repackaging drugs received from another pharmacy?

When repackaging drugs received from another pharmacy, it is essential to record the name of the drug, its strength, the quantity being repackaged, the expiration date, the lot number, and the manufacturer. This recording serves several crucial functions. It ensures that the repackaged medication can be accurately identified and traced back to the original source, which is important for both safety and compliance purposes. The lot number helps track any potential recalls or adverse events related to that specific batch, while the expiration date ensures the medication’s efficacy and safety when administered to patients. Collecting this detailed information is vital in maintaining records for regulatory purposes and ensuring high standards of pharmaceutical care.

Other options do not encapsulate all the necessary details pertinent to the repackaging process. For instance, while the date received and the pharmacist's registration number are important for record-keeping, they do not provide specific information about the medications themselves. Similarly, patient information and prescription details, as well as prescribing physician contact information, are related to dispensing medication rather than the repackaging process.
