The first U.S. Food and Drug Administration approved product for pain control in a food-producing animal was released last month by Merck Animal Health. Banamine Transdermal (flunixin transdermal solution) is approved for pain associated with foot rot and fever resulting from bovine respiratory disease and is applied as a pour-on. The product requires a prescription from a veterinarian, but producers can apply it themselves.
Field studies reported animals diagnosed with BRD and treated with the product had at least a 2-degree Fahrenheit drop in temperature within six hours of treatment. With regard to pain from foot rot, there was a 93.3% to 100% improvement in lameness scores on treated cattle.
