The agency notes in the guidance that injectable vial misuse, including unsafe handling and injection techniques, “has led to vial contamination and an increased risk of blood-borne illness transmission between patients.” Inappropriate excess volume and labeled vial ﬁll sizes, it maintains, are two factors that may contribute to unsafe handling and injection practices by consumers and health care providers. It points out that even when appropriately labeled, single-dose vials that contain signiﬁcantly more drug than is required for a single dose may result in the misuse of the leftover drug product. The guidance clariﬁes the agency’s position on vial overﬁlling and makes recommendations on vial ﬁll levels based on the product type and intended use. The draft was released in March 2014, and no comments were submitted to the agency.
