For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

Omega-3 fatty acids at pharmacological doses can modestly impair platelet aggregation and may prolong bleeding time. Taken with clopidogrel, this may add to the bleeding tendency, although clinically significant bleeding is uncommon.

What this interaction means in plain words

Clopidogrel and Fish oil triglycerides can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Moderate

Why it happens

Additive antiplatelet effects through reduced thromboxane A2 production and platelet aggregation alongside P2Y12 receptor blockade.

What to do

Monitor for bleeding such as bruising, epistaxis or gastrointestinal blood loss. Reassess the need for fish oil if bleeding occurs, particularly with high doses or additional antithrombotics.

What to ask your pharmacist
