No Interaction Expected
Emtricitabine/Tenofovir-DF (FTC/TDF, PrEP)
Quality of Evidence:
Coadministration with a desogestrel-containing progestogen-only pill (POP) has not been studied but based on metabolism and clearance a clinically significant interaction is unlikely. Desogestrel is a prodrug which is activated to etonogestrel by CYP2C9 (and possible CYP2C19); the metabolism of etonogestrel is mediated by CYP3A4.
