What the interaction means

Metformin's FDA label names ~19 drugs/classes affecting glycemic control or lactic-acidosis risk (carbonic anhydrase inhibitors, ranolazine, alcohol, diuretics, corticosteroids, and more) -- atorvastatin is not among them. Atorvastatin's own FDA label is mostly CYP3A4-mediated interactions (cyclosporine, gemfibrozil, several CYP3A4 inhibitors, rifampin) -- metformin is not among them either.

No documented interaction between Atorvastatin and Metformin 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

Metformin's and atorvastatin's FDA labels were checked directly, full text, in both directions. Neither drug is metabolized through pathways the other's label names as a concern.
