Does Tenofovir Interact with Elvitegravir Cobicistat Emtricitabine And Tenofovir Disoprox?
CDI records a unknown classification for Tenofovir and Elvitegravir Cobicistat Emtricitabine And Tenofovir Disoprox. The stored summary is: 7.4 Drugs Affecting Renal Function Because emtricitabine and tenofovir, components of STRIBILD, are primarily excreted by the kidneys by a combination of glomerular filtration and active tubular secretion, coadministration of STRIBILD with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of emtricitabine, tenofovir, and other renally eliminated drugs and this may increase the risk of adverse reactions. Hepatitis C Antiviral Agents: ledipasvir/sofosbuvir sofosbuvir/velpatasvir sofosbuvir/velpatasvir/voxilaprevir ↑ tenofovir The safety of increased tenofovir concentrations in the setting of HARVONI ® (ledipasvir/sofosbuvir) and STRIBILD has not been established. Patients receiving STRIBILD concomitantly with EPCLUSA ® (sofosbuvir/velpatasvir) or VOSEVI ® (sofosbuvir/velpatasvir/voxilaprevir) should be monitored for adverse reactions associated with tenofovir disoproxil fumarate. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.
