Patients with vitamin E toxicity are likely to have been using vitamin E supplements; obtain the dose and duration of vitamin E usage. Assess concurrent use of anticoagulants or aspirin. Since vitamin E may block absorption of vitamin K, a nutritional assessment for vitamin K deficiency is useful in patients who present with bleeding and a prolonged prothrombin time (PT).
