The expiration date on a commercial pharmaceutical product is July 2016. When will this product be considered expired?

The expiration date on a commercial pharmaceutical product indicates the last date that the manufacturer guarantees the product will maintain its optimal efficacy and safety. For a product with an expiration date set for July 2016, it would be considered expired after the final day of that month, July 31st.

This means that the product remains effective up until the very last second of July 31st, but after that date, it would no longer be recommended for use. Therefore, the product is indeed regarded as expired starting on August 1st. This understanding is crucial in pharmaceutical management to ensure patient safety and the appropriate use of medications.
