What are the outdates for manufacturing and amber vial storage?

• A. manufacture-90 days; amber vials-30 days
• B. manufacture-30 days; amber vials-90 days
• C. manufacture-180 days; amber vials-60 days
• D. never expire

Answer: (A)

This question tests how packaging and storage affect how long a product stays stable. When a product is manufactured, its expiration is based on stability data for the product in its original packaging and storage conditions, which here corresponds to 90 days. If the product is stored in amber vials, even though those vials block light, the repackaged form introduces additional handling and container-closure factors, so the stability data support a shorter period—30 days—to protect potency and safety. In practice, repackaged or stored-in-secondary-packaging items often have a more conservative beyond-use date. So the best fit is 90 days for manufacturing and 30 days for amber vial storage.
