In what year was extra-label use of fluoroquinolones and glycopeptides prohibited?

• A. 1996
• B. 1998
• C. 1997
• D. 1999

Answer: (C)

Understanding this asks about a regulatory action that restricts extra-label use of specific antimicrobials in food-producing animals. Extra-label use means using a drug in a way not specified on its label, such as for a different species, dose, or condition. Regulators restrict ELDU to protect public health from antimicrobial resistance and to prevent drug residues from entering the food supply. In 1997, the FDA prohibited extra-label use of fluoroquinolones and glycopeptides in food-producing animals. These drug classes are highly important in human medicine, so limiting their use outside labeled indications helps reduce the risk of resistant bacteria developing and spreading to people. The other years listed do not reflect when the prohibition occurred; the initial prohibition was in 1997, with later clarifications and policy updates occurring afterward.
