Strongly induce CYP3A, which may lead to lower exposure of one or more components and loss of efficacy of GENVOYA and possible resistance.

Drugs that induce CYP3A activity are expected to increase the clearance of elvitegravir and cobicistat, resulting in decreased plasma concentration of cobicistat, elvitegravir, and TAF, which may lead to loss of therapeutic effect of GENVOYA and development of resistance (see Table 5 ).

Anticonvulsants: carbamazepine phenobarbital phenytoin ↓ elvitegravir ↓ cobicistat ↓ TAF Coadministration with carbamazepine, phenobarbital, or phenytoin is contraindicated due to potential for loss of therapeutic effect and development of resistance. oxcarbazepine Alternative anticonvulsants should be considered when GENVOYA is administered with oxcarbazepine.…
