Summary
Omega-3 fatty acids can mildly impair platelet function. With heparin, this could add slightly to bleeding risk, but controlled data show little clinically meaningful effect.
What this interaction means in plain words
Heparin 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: platelet inhibition by omega-3 combined with heparin-mediated antithrombin potentiation.
What to do
Monitor for bleeding and follow routine aPTT or anti-Xa monitoring for heparin. Reassess the supplement if bleeding occurs.
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?
