US EditionBoehringer Ingelheim Secures Emergency Use Authorization for IVOMEC® (Ivermectin) 1% Injection to Help Protect Cattle Against New World Screwworm
The FDA authorized IVOMEC for screwworm prevention in U.S. cattle amid rising risk from northern Mexico; no approved alternatives exist for critical intervention points, officials said.
- On Feb. 5, 2026, the FDA issued an Emergency Use Authorization allowing IVOMEC 1% Injection to prevent New World screwworm in cattle, as announced by Boehringer Ingelheim Animal Health USA Inc., Duluth, Ga.
- With Mexico detections raising risk, recent New World screwworm cases in northern Mexico prompted the FDA to determine there was no approved, adequate alternative at critical intervention points.
- The EUA authorizes IVOMEC when administered within 24 hours of birth, at castration, or at wound appearance, excluding female dairy cattle producing milk for human consumption and calves processed for veal, with a safety interval of not treating cattle within 35 days of slaughter.
- The EUA provides cattle producers and veterinarians an important preventive tool, industry and officials said, with Dr. Gustavo Sabatini emphasizing the need for access to preventive tools and producer education.
- This authorization is the first over-the-counter EUA for NWS prevention under section 564 of the FD&C Act, limited to the emergency duration, as Boehringer Ingelheim serves about 54,500 employees across over 130 markets.
