  • Incidents that cause the drug product or its labeling to be mistaken for or applied to another article;
  • Bacterial contamination;
  • Any significant chemical, physical, or other change or deterioration in the distributed drug product;
  • Any failure of one or more distributed batches of the drug product to meet the specifications established in its application.
