Follow-up

Further Inpatient Care

  • Patients with vitamin E toxicity require hospitalization only if bleeding complications, including intracranial hemorrhage, occur.
    • If an intracranial hemorrhage is suggested or the patient has focal neurologic findings on examination, order a head CT scan without contrast to rule out an existing hemorrhage.
    • If hemorrhage is present, the patient should receive inpatient medical management, with a neurosurgeon consulted for possible drainage of the fluid collection.
  • Patients who present with other forms of bleeding should receive vitamin K and should be observed until they are stable, with follow-up evaluation provided on an outpatient basis.

Further Outpatient Care

  • Patients with vitamin E toxicity who are stable can be treated in an outpatient setting, with periodic monitoring of the PT to ensure its return to normal levels if bleeding develops.

Deterrence/Prevention

  • Individuals can avoid vitamin E toxicity by adhering to the daily recommended dosages of the vitamin and through monitoring of PT when anticoagulants are being taken.
  • Patients with nutritional deficiency should increase their intake of vitamin K to prevent bleeding complications.

Prognosis

  • In most patients with vitamin E toxicity, the prognosis is excellent once the supplements are discontinued.
  • Patients with mild bleeding episodes are likely to fully recover once vitamin K is administered and the vitamin E supplements are discontinued.
  • Patients with intracranial hemorrhage have an increased mortality rate; however, with proper diagnosis and management, many patients with this condition survive and recover some or all of their previous functions.

Miscellaneous

Medicolegal Pitfalls

  • A medical and/or legal problem could arise if a patient develops a significant bleeding complication as a result of a physician-prescribed combination of oral anticoagulants and vitamin E without warning the patient of the increased risk of bleeding and elevated INR.
  • If a patient is taking vitamin E while on oral anticoagulants, warn the patient of the possible adverse bleeding effects and recommend limiting vitamin E intake to the RDA (15 mg/d).
  • Warn patients taking high doses of vitamin E (400 IU or more) that no compelling evidence exists that vitamin E reduces cardiovascular risk or cancer and that it may increase heart failure and mortality, especially in patients with chronic diseases.
  • Warn patients taking lipid-lowering agents that vitamin E may blunt the beneficial effect on HDL.
