No Interaction Expected
Emtricitabine/Tenofovir-DF (FTC/TDF, PrEP)
Cat's Claw (Uncaria tomentosa)
Quality of Evidence:
Coadministration has not been studied but based on metabolism and clearance a clinically significant interaction is unlikely. Cat’s claw was demonstrated to strongly inhibit CYP3A4 in vitro, but emtricitabine and tenofovir-DF do not undergo CYP3A4 metabolism.
