The U.S. Food and Drug Administration has issued Emergency Use Authorization (EUA) for IVOMEC® (ivermectin) 1% Injection for the prevention of infestations caused by New World screwworm (NWS) in cattle.
NWS is a destructive parasite that can severely impact animal health. Should it advance into the United States, this authorization gives veterinarians and cattle producers an important preventive tool to help protect herds – and, in turn, safeguard the food supply and the livelihoods of cattle producers.
This is the first EUA for any over-the-counter drug for the prevention of NWS infestations in cattle. You can learn more about how it helps strengthen U.S. preparedness right here: https://go.boehringer.com/NW65r
For full prescribing information, see package insert or speak with your veterinarian.
