Rising numbers of patients requiring warfarin, as well as increasing long term use, causes some haemorraghic complications. Intracerebral haemorrhage is one of these complications. An 88 year old patient was admitted to our emergency department with acute loss of sodium (5 mg/day) visual acuity. INR was 6.24 in laboratary findings. The patient had a stroke three years previously and used warfarin sodium (5 mg/day) for anticoagulation. Bilateral occipital haemorrhage was diagnosed in cerebral tomography. The patient was discharged from neurological care 20 days after admission. We suggest that the incidence of cerebral haemorrhage due to warfarin overdose will increase due to growing rates of anticoagulant treatment in the population}, number={2}, publisher={Acil Tıp Uzmanları Derneği}
