التداخل بين إلفيتيغرافير وكوبيسيستات وإمتريسيتابين وتينوفوفير وفوسامبرينافير

GENVOYA should not be administered with other antiretroviral medications for treatment of HIV-1 infection.

Not Recommended with Other Antiretroviral Medications GENVOYA is a complete regimen for the treatment of HIV-1 infection; therefore, coadministration of GENVOYA with other antiretroviral medications for treatment of HIV-1 infection should be avoided.

Complete information regarding potential drug-drug interactions with other antiretroviral medications is not provided [see Contraindications (4) , Warnings and Precautions (5.2) and Clinical Pharmacology (12.3) ] .

Coadministration of GENVOYA with other drugs that inhibit CYP3A may decrease the clearance and increase the plasma concentration of cobicistat.

Lactic Acidosis/Severe Hepatomegaly with Steatosis Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs, including emtricitabine, a component of GENVOYA, and tenofovir DF, another prodrug of tenofovir, alone or in combination with other antiretrovirals.

Because ritonavir is a CYP2D6 inhibitor, clinically significant interactions with drugs metabolized by CYP2D6 are possible when coadministered with fosamprenavir calcium plus ritonavir.
