The ASTM D4774-17 specification details requirements for drug labeling on unlabeled syringes filled out by the user or their agent, including size, Color, pattern, and type. These labels are used to identify drug content, whereas labels affixed by drug manufacturers are not covered by the specification. The standard specifies the size, background color, type of printing, and Color of the label to ensure clear identification of the drug. While the use of Color is intended to help identify drug categories, users are still required to read the label carefully before use. The standard also recommends the use of SI units, emphasizing that the design of the label should comply with safety and regulatory requirements.
