What is generally indicated by the last digits of an NDC?

The last digits of an NDC, or National Drug Code, typically indicate the package size of the medication. An NDC is structured to provide specific information about the drug, including the labeler, product code, and package code. The first segment identifies the manufacturer, the second segment defines the specific drug product such as its strength, dosage form, and formulation, while the last segment reveals details about the packaging, including the size and type of the container. This systematic coding allows for effective tracking and identification of medications in various forms and quantities. Understanding this structure is crucial for pharmacy technicians to ensure proper dispensing and inventory management.
