title: Possible unaware intoxication by anticoagulant rodenticide.
abstract: Superwarfarin toxicity may be a serious problem. It needs high clinical suspicious in patients with bleeding diathesis without hematologic or liver diseases even in patients with apparent negative history of warfarin or other anticoagulant accessibility. Here we reported a patient with a negative history of any medical diseases or drug administration who was referred with generalized ecchymosis. Increased international normalized ratio and decreased vitamin K-dependent coagulation factors were detected in this patient. His hematologic and liver evaluations were normal. Clinical pharmacist emphasis in taking history revealed using anticoagulant rodenticide all over the farm the patient lived in that might result in unaware intoxication in this patient who suffered dementia.
