What is the difference between a BUD date and an expiration date?

The correct answer highlights an important aspect of managing pharmaceuticals, particularly in relation to repackaging and storage. The Beyond Use Date (BUD) is a date assigned by the pharmacy when a medication is repackaged or compounded. It indicates the last date the medication should be used to ensure its efficacy and safety after it has been prepared or altered from its original form. This is crucial because factors such as storage conditions and the nature of the existing formulation can affect how long the drug remains stable after repackaging.

In contrast, the expiration date is determined by the manufacturer and reflects the time frame in which the product is expected to remain effective and safe when stored as directed. This date is established based on stability studies conducted during the product's development.

Understanding the distinct roles of BUD and expiration dates helps pharmacy technicians ensure that medications are used within safe and effective time frames, thus protecting patient safety and maintaining the integrity of pharmaceutical care.
