No Interaction Expected
Emtricitabine/Tenofovir-DF (FTC/TDF, PrEP)
Pyridoxine (Vitamin B6) [alone]
Quality of Evidence:
Coadministration has not been studied but based on metabolism and clearance a clinically significant interaction is unlikely. Pyridoxine is absorbed from the GI tract and is converted to the active form pyridoxal phosphate. It is excreted in the urine as 4-pyridoxic acid.
