Federal regulators have authorized a generic ivermectin injection named Bimectin for preventing New World screwworm in cattle. The Food and Drug Administration granted emergency use authorization for Bimectin, which can be administered within 24 hours of birth, during castration, or when wounds appear. However, it is not approved for use in lactating dairy cows or veal calves. Bimectin is a generic version of Ivomec, previously authorized by the FDA. Bimeda Animal Health, an Ireland-based company, applied for Bimectin's approval. FDA officials determined that the injection can prevent screwworm in cattle, with benefits outweighing the risks. This conclusion is supported by studies from Brazil and Argentina demonstrating ivermectin's effectiveness. The FDA also confirmed the safety of food products from treated animals for human consumption. This authorization aims to increase generic drug options against New World screwworm, preventing producer reliance on a single manufacturer. Ivermectin, an antiparasitic medication, is used in animals and humans. New World screwworm recently entered the United States from Mexico. The Trump administration has authorized numerous drugs for screwworm prevention and treatment. Recent USDA data indicates screwworm cases continue to be reported, primarily in Texas.
