Rat poison contains a variety of ingredients that work together to kill rodents; however, these substances are also lethal to humans if ingested. The amount of time it takes for symptoms to appear depends upon the amount of rat poison ingested and the number of days it is ingested. It is important to note that symptoms of rat poisoning may occur even when a person hasn’t ingested rat poison. This is because warfarin, a component of rat poison, is also used in medicine as a blood thinner.
When rat poison is ingested, sudden nose bleeds that are difficult to control may occur 2. Additionally, the person may bruise easily and cuts may take longer than normal to clot. Even normal contact with everyday items may cause a bruise. Women may notice bruising under bra straps. Bruising may be noticed near waistbands, watches or rings.
