“The U.S. Food and Drug Administration (FDA) released new antibiotic guidance pertaining to animal drugs containing medically-important antimicrobials for use in companion and food production animals that are currently approved for over-the-counter (OTC) marketing.
Under the guidance, FDA stated several antibiotics familiar to ranchers and other livestock owners will no longer be available OTC.
The intent of the new antibiotic guidance is to ensure animal drugs that contain antimicrobials important for humans are not being overused or used incorrectly”
