Summary
High-dose omega-3 fatty acids have mild antiplatelet effects and may modestly prolong bleeding time. Combined with the anticoagulant dabigatran, this could add slightly to bleeding risk, although clinically significant bleeding is not well documented.
What this interaction means in plain words
Dabigatran and Omega have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Additive pharmacodynamic effect: omega-3 fatty acids reduce platelet aggregation while dabigatran directly inhibits thrombin.
What to do
No dose change is usually needed; ask patients about bruising and bleeding and review omega-3 intake if bleeding occurs. Be more attentive with high-dose omega-3 products or with additional antithrombotic drugs.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
