Coumatetralyl is an anticoagulant of the warfarin type. Symptoms of overexposure relate to failure of the blood clotting mechanism and include bleeding gums and failure of blood clotting after skin wounds. After one exposure the toxicity of coumatetralyl is relatively low, however if overexposure continues for several days the product becomes more toxic. The product must therefore be constantly present in the bloodstream for more than 1 to 2 days in order to be highly toxic. A single exposure, even though relatively large, may not produce toxic symptoms as the compound is quite rapidly metabolised. Chronic animal studies show no evidence of carcinogenic or teratogenic effects.
