Can You Take Copper and Warfarin Together?

Copper's own NIH fact sheet states it is not known to interact with any medications, and no interaction with warfarin is documented.

No documented interaction identifiedEvidence: High

What the interaction means

The NIH Office of Dietary Supplements' copper fact sheet states plainly: "Copper is not known to interact with any medications." Warfarin's own FDA label does not mention copper.

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

Copper's own source gives an explicit negative statement, which is why this is rated higher evidence quality than most other 'no documented interaction identified' pairs.
