No Interaction Expected
Emtricitabine/Tenofovir-DF (FTC/TDF, PrEP)
Quality of Evidence:
Coadministration has not been studied but based on metabolism and clearance a clinically significant interaction is unlikely. Metformin is primarily eliminated by the kidney and in vitro data suggest that it is a substrate of the renal transporter OCT2. An interaction is unlikely as emtricitabine and tenofovir are primarily excreted by different renal transporters.
