FDA Grants Emergency Use Authorization for Ivermectin Liquid to Prevent New World Screwworm in Horses

The U.S. Food and Drug Administration has issued an Emergency Use Authorization for an ivermectin oral solution intended for horses, aimed at preventing infestations by New World screwworm.

The authorization specifies that the product may be administered within the first 24 hours after birth or at the time a wound is first treated, and it is limited to equine use only.

The decision is presented as part of the current administration’s strategy to shield American agriculture from the threat posed by the parasite, with officials from Health and Human Services and the Department of Agriculture emphasizing its importance.

Authorities said the EUA broadens the nation’s defensive tools and helps protect livestock, wildlife and the surrounding communities.
