An NDB code, or National Drug Code, is a unique identifier assigned to each medication in the United States. This code helps in the identification, registration, and tracking of drugs. The NDB code consists of three segments: the labeler code, the product code, and the package code. It is essential for healthcare professionals to accurately record and communicate NDB codes to ensure patient safety. Pharmacists and healthcare providers use NDB codes to verify the correct medication and dosage. Understanding NDB codes is crucial for efficient medication management and patient care.
