Diphenadione is a vitamin K antagonist that has anticoagulant effects and is used as a rodenticide against rats, mice, voles, ground squirrels and other rodents. The chemical compound is an anti-coagulant with active half-life longer than warfarin and other synthetic 1,3-indandione anticoagulants.[1][2]

It is toxic to mammals, in all forms; exposure and oral ingestion of the toxin may cause irregular heartbeat and major maladies associated with its impact on blood clotting, depending on dose.[3] As a "second-generation" anticoagulant, diphenadione is more toxic than the first generation compounds (e.g., warfarin).[4]Template:Rp For purposes of treating toxicity on exposure, diphenadione is grouped with other vitamin K antagonists (coumarins and indandiones); despite being directed at rodents and being judged as less hazardous to humans and domestic animals than other rodenticides in useScript error: No such module "Unsubst". (by the U.S. Environmental Protection Agency), indandione anticoagulants, nevertheless, "may cause human toxicity at a much lower dose than conventional 'first-generation anticoagulants'… and can bioaccumulate in the liver."[5]Template:Rp
