What the interaction means

Aspirin's own DURLAZA FDA label does not name metformin anywhere in its Drug Interactions section. Metformin's own FDA label does not mention aspirin or salicylate; its Drug Interactions section names carbonic anhydrase inhibitors, drugs affecting renal clearance, alcohol, and other glycemic-control agents.

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.
