Pregnancy Risk Factor: C

Vitamin E crosses the placental boundary
As pregnancy progresses, maternal serum levels of tocopherol rise.
Patients who are pregnant do not need to take an extra dose.

Use during breastfeeding:

It is excreted from breast milk.
The concentrations in the breasts are highest immediately after birth and gradually decrease with time.
Breast concentration is affected by maternal intake
Supplementation for breastfeeding mothers is not necessary.

Vitamin E Dose in kidney disease:

The manufacturer has not recommended any dose adjustment in patients with renal disease.

Vitamin E Dose in liver disease:

It may cause the deficiency of vitamin K. Patients with cirrhosis are deficient in coagulation factors.
Its use may further lead to worsening of the bleeding diathesis as seen in patients with liver disease. It should be used with caution.

Side effects of Vitamin E:

There are no adverse reactions related to its use listed in the manufacturer’s labeling.

Contraindications to Vitamin E (Evion):

Allergy to tocopherol (vitamin A) or any component in the formulation

Vitamin E (systemic): Drug Interaction

Risk Factor C (Monitor therapy)
Agents with Antiplatelet Properties (e.g., P2Y12 inhibitors, NSAIDs, SSRIs, etc.)	Vitamin E (Systemic) may enhance the antiplatelet effect of Agents with Antiplatelet Properties.
Anticoagulants	Vitamin E (Systemic) may enhance the anticoagulant effect of Anticoagulants.
CycloSPORINE (Systemic)	Vitamin E (Systemic) may decrease the serum concentration of CycloSPORINE (Systemic).
Ibrutinib	Vitamin E (Systemic) may enhance the antiplatelet effect of Ibrutinib.
Risk Factor D (Consider therapy modification)
Orlistat	May decrease the serum concentration of Vitamins (Fat Soluble). Management: Administer oral fat soluble vitamins at least 2 hours before or after the administration of orlistat. Similar precautions do not apply to parenterally administered fat soluble vitamins.
Tipranavir	May enhance the adverse/toxic effect of Vitamin E (Systemic). Management: Patients taking tipranavir oral solution are advised to avoid taking additional vitamin E, beyond the amounts contained in a multivitamin product. This interaction does not apply to tipranavir capsules.

Monitoring Parameters:

Monitoring is usually not required, however, plasma tocopherol concentrations may be done.

How to administer Vitamin E (Evion)?

The capsules should be swallowed whole. It should not be crushed or chewed.

Mechanism of action of Vitamin E (Evion):

It protects vitamin A and C from oxidation, protects membranes from free radical attack, and protects red blood cells against hemolysis.

AbsorptionMalabsorption is lower in premature infants, low birth weight infants, and malabsorption. Higher doses of bile are more effective for absorption.
