No Interaction Expected
Emtricitabine/Tenofovir-DF (FTC/TDF, PrEP)
Norethisterone [Norethindrone] (POP)
Quality of Evidence:
Coadministration of a norethisterone progestogen-only pill (POP) has not been studied but based on metabolism and clearance a clinically significant interaction is unlikely. Norethisterone is metabolized by CYP3A4. Emtricitabine/tenofovir-DF does not interact with this metabolic pathway.
