What the interaction means

Omega-3's own NIH ODS fact sheets name only warfarin and similar anticoagulants as a documented medication interaction. Losartan's own FDA label does not mention omega-3, fish oil, EPA, or DHA anywhere.

No documented interaction was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

Both substances' own current authoritative sources were checked directly, full text, in both directions.
