## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental new animal drug application (NADA) filed by Elanco Animal Health. The supplemental NADA provides for minor revisions to labeling of monensin Type A medicated articles for chickens. FDA is also amending the regulations to simplify the organization of special labeling requirements for formulations (Type A medicated articles, Type B and Type C medicated feeds) containing monensin for poultry and game birds. This action is being taken to improve the clarity of the regulations.
