WASHINGTON, D.C. (RFD NEWS) — Efforts to combat New World screwworm received another boost this week after the Food and Drug Administration (FDA) issued an Emergency Use Authorization for the first generic over-the-counter (OTC) treatment approved for dogs and cats exposed to the pest.
The medication is available in two dosage strengths and is administered based on an animal’s weight. According to FDA officials, the treatment kills most screwworm larvae within hours of administration and is followed by a second dose.
The authorization comes as federal and state animal health agencies continue efforts to contain the pest following multiple confirmed cases in the United States.
Federal officials say the authorization provides veterinarians, pet owners, and animal health professionals with an additional tool as containment and eradication efforts continue in response to recent detections in Texas.
In a statement, U.S. Secretary of Health & Human Services Robert F. Kennedy Jr. said the approval reflects the government’s continued focus on preventing the pest’s spread:
Officials say the treatment adds another layer of protection as animal health authorities work alongside the USDA and state agencies to contain the New World screwworm and prevent further infestations.
The authorization applies to companion animals, while separate treatment and prevention strategies remain in place for livestock producers monitoring cattle and other susceptible animals in affected regions.
