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[verification needed] longer than warfarin and other synthetic indandione anticoagulants.[better source needed]
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.[verification needed][better source needed] As a "second-generation" anticoagulant, diphenadione is more toxic than the first generation compounds (e.g., warfarin).:436 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 use (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.":173

The first-generation anticoagulants, for example, are reasonably effective against pest rodents and are less toxic than second-generation anticoagulants… / Very small amounts of the extremely toxic rodenticides sodium fluoroacetate, fluoracetamide, strychnine, crimidine, yellow phosphorus, zinc phosphide and thallium sulfate can cause severe and even fatal poisoning. Cholecalciferol is also a highly toxic agent. The anticoagulants, indandiones and red squill, are less hazardous to humans and domestic animals. Some of the newer anticoagulant compounds, termed 'second-generation anticoagulants,' may cause human toxicity at a much lower dose than conventional 'first-generation anticoagulants'… and can bioaccumulate in the liver…CS1 maint: Multiple names: authors list (link) CS1 maint: Extra text: authors list (link) [p. 173, emphasis in source].
