A 67‐year‐old man was admitted to the emergency department about 5 h after deliberate self‐poisoning with 300 mg of Apixaban. The clinical examination did not show any organ dysfunctions or haemorrhagic signs, and the patient's life was not in danger. The first analysis, upon admission, showed a concentration of 2655 μg l−1 of Apixaban. The Cmax was observed 17 h after the intake (3654 μg l−1), about four times the classical Tmax value (median [range]: 4 h [2–4]). The Apixaban was then eliminated following a first order elimination with a calculated half‐life of 10.8 h. The anti‐Xa activity seems to be linearly related to concentration up to 4000 μg l−1. This report suggests that the use of activated charcoal should be effective up to 17 h after a massive intake. A 67‐year‐old man was admitted to the emergency department about 5 hours after deliberate self-poisoning with 300 mg of Apixaban.The clinical examination did not show any organ dysfunctions or haemorrhagic signs.Due to delayed absorption of the drug, this case report suggests that activated charcoal may have been effective even when used beyond the 6th hour after a massive ingestion of Apixaban, order to reduce overexposure.
