T45: Poisoning by primarily systemic and haematological agents, not elsewhere classified

T45.5: Poisoning: Anticoagulants

A drug can cause poisoning if, for example, too much of it is taken. The drug may also be administered or taken by mistake.

Platelets and various clotting proteins in the blood are involved in blood clotting. The platelets can adhere to one another in such a way that they stop a bleed. The clotting proteins stabilize the platelets that have stuck together. This enables wounds to heal, for example.

Anticoagulant drugs reduce the risk of blood clots forming in the bloodstream. These drugs can be used after strokes or heart attacks, among other things. The drugs can cause a person to bleed more heavily or easily than usual.
