What term refers to the date after which a pharmaceutical product should not be dispensed or used?

The term that specifically refers to the date after which a pharmaceutical product should not be dispensed or used is "Beyond Use Dating." This term is critical in pharmacy practice as it indicates the time frame in which a medication remains stable and effective when stored under specified conditions after its dispensing. Beyond use dating is especially important for compounded medications, as their stability may diminish more quickly compared to commercial products.

The other terms provided do not accurately represent this concept. "Expiration Period" typically refers to the shelf life of a commercial product, which is determined by the manufacturer based on stability testing prior to entering the market. The "Manufacturing Date" indicates when the product was produced, which is essential for understanding the age of the medication but does not reflect its usability over time. "Usage Deadline," while it intuitively suggests an end point for use, is not a standardized term in the pharmacy field and does not convey the specific implications related to pharmaceutical stability and safety.
