The supplemental NADA adds a precaution to labeling that the product is for oral use in horses and ponies 6 months of age and older. The supplemental NADA is approved as of May 29, 2003, and the regulations are amended in 21 CFR 520.1452 to reflect the approval and to reflect current format. The basis of approval is discussed in the freedom of information summary.
