FDA Grants Emergency Use Authorization for Elanco's Wound Spray to Prevent Screwworms

The U.S. Food and Drug Administration (FDA) has granted Emergency Use Authorization for Elanco's CLiK™ Extra (dicyclanil topical suspension). This wound spray is now authorized for application on or around wounds to prevent infestation by the New World screwworm (Cochliomyia hominivorax) in a variety of livestock, as well as captive and captured wildlife species.

This authorization provides livestock producers with a critical tool in combating the screwworm, a parasite that can cause significant harm to animals and substantial economic losses to agricultural operations. The New World screwworm lays its eggs in the wounds of animals, and the resulting larvae consume living tissue, potentially leading to severe infections, tissue damage, and death.

Elanco previously received approval for its CLiK™ product, also aimed at screwworm prevention. The Emergency Use Authorization for CLiK™ Extra is specific to the United States and is subject to certain conditions. According to Elanco's technical experts, vigilance and early intervention are key to minimizing animal injury and limiting the spread of this parasite.

The screwworm poses a serious threat to animal health and agricultural economies. The ability to quickly deploy effective treatments like CLiK™ Extra is crucial for managing and preventing widespread outbreaks and protecting animal populations.
