Anticoagulant-induced haemorrhage in the upper airway is rare, but it can be life threatening if airway obstruction develops. Treatment is mainly conservative. Urgent control of airway and coagulopathy are the essential of management. Vitamin K1 or combination of fresh frozen plasma and vitamin K1 should be used for reversal of the coagulopathy. In this report, two elderly patients were reported to have oral anticoagulant (warfarin)-induced haemorrhage in the sublingual and supraglottic areas.
