An opened multidose vial must be labeled with which of the following?

An opened multidose vial must be labeled with specific information to ensure safety and proper use. This includes the date and time the vial was opened, the initials of the person who opened it, and the discard date.

The date and time of opening are crucial as they help track how long the vial has been in use, thus ensuring the medication's stability and efficacy are maintained. The initials of the person who opened the vial provide accountability and traceability back to the individual who handled the medication. Lastly, the discard date indicates when the medication should no longer be used, adhering to safety protocols and reducing the risk of contamination or degradation.

This comprehensive labeling system is critical for maintaining patient safety and medication integrity in a clinical setting.
