Treatment
Medical Care
- Intramuscular administration is necessary when the deficiency results from a low concentration of bile salts in the lumen of the small intestine, because these patients are unable to absorb oral preparations.
- Treatment, which may include oral or parenteral vitamin supplementation, must be designed to address the underlying cause of the deficiency.4
Consultations
Consult a gastroenterologist if biliary problems are the underlying cause of vitamin E deficiency.
Medication
The RDA of alpha tocopherol according to age (see Image 1) is as follows:
- Age 0-6 months - 3 mg
- Age 6-12 months - 4 mg
- Age 1-3 years - 6 mg
- Age 4-10 years - 7 mg
- Adults and elderly individuals - 8-10 mg
Vitamin E supplementation is important, because apparently effective doses are beyond the maximum dietary intake. Supplementation with vitamin E is extremely safe except when normal coagulation mechanisms are impaired.
Replacement recommendations according to disease state are as follows:
- Abetalipoproteinemia - 100-200 IU/kg/d
- Chronic cholestasis - 15-25 IU/kg/d
- Cystic fibrosis - 5-10 IU/kg/d
- Short-bowel syndrome - 200-3600 IU/d
- Isolated vitamin E deficiency - 800-3600 IU/d
Pregnancy/lactation
Vitamin E is in the Food and Drug Administration's (FDA's) pregnancy category A. Breastfeeding is safe.
Vitamins
Essential for normal cell function.
Vitamin E (alpha tocopherol)
Protects cell membranes from free radical attacks.
Adult
RDA dose: 8-10 mg/d (12-15 IU/d) PO
Therapeutic dose: 50-2000 IU/d PO
Deficiency: Tab/cap 30-50 mg qd (PO dose usually 4-5 times the RDA)
Pediatric
RDA dose: 3-10 mg/d PO
Therapeutic dose: 1-100 mg/kg/d PO
Reduced absorption with bile sequestrants; may enhance response to oral anticoagulants, perhaps because of interference with effect of vitamin K in clotting factor synthesis
For patients on warfarin or dicumarol, large doses may prolong PT
Documented hypersensitivity; PO use contraindicated in coagulation disorders or with anticoagulant therapy
Pregnancy
A - Fetal risk not revealed in controlled studies in humans
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
May induce vitamin K deficiency; necrotizing enterocolitis may occur when large doses given; occasional muscle weakness, fatigue, headaches, and nausea may occur; thrombophlebitis has been reported in patients at risk for small vessel disease taking 400 or more IU
