CautionEmerging evidence
What is happening. Vitamin E may increase bleeding tendency and can be a concern with Icosapent Ethyl when high-dose vitamin E is combined with omega-3 therapy or antithrombotic drugs.
Mechanism. Additive platelet or coagulation effects can become clinically relevant when the drug or disease state increases bleeding risk.
Recommendation. Avoid high-dose use unless the prescriber agrees; seek care for unusual bruising, bleeding, black stools, or severe headache.
