## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of two supplemental new animal drug applications (NADAs) filed by Novartis Animal Health US, Inc. The supplemental NADAs provide for removal of a 250-pound weight restriction and the addition of a reproductive caution statement to labeling of tiamulin medicated feeds used for the treatment or control of certain bacterial enteric diseases in swine.
