Anticoagulant Rodenticide Ingestion
The EPA has banned public use of brodifacoum, bromadiolone, difenacoum, and difethialone. These products were manufactured for home use until December 31, 2014, and shipped until March 2015. The new products contain diphacinone, and 4 weeks of vitamin K1 therapy is currently recommended to treat this anticoagulant rodenticide (ACR). These changes may decrease ACR toxicities and increase cases of other rodenticide toxicities, particularly bromethalin, which can cause neurotoxicity.
