Quizplus · Accepted Answer

A multi-dose vial can be used for up to 28 days once opened, unless otherwise specified by the manufacturer. This is to ensure sterility, and stability of the drug product. Not all vials are multi-dose vials; the pharmacy technician should always verify if the vial is multi-dose or single use by checking the label on the vial.
