Does Tenofovir Interact with Emtricitabine Rilpivirine Hydrochloride And Tenofovir Alafen?
CDI records a unknown classification for Tenofovir and Emtricitabine Rilpivirine Hydrochloride And Tenofovir Alafen. The stored summary is: 7.6 Drugs Affecting Renal Function Because FTC and tenofovir are primarily excreted by the kidneys by a combination of glomerular filtration and active tubular secretion, coadministration of ODEFSEY with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of FTC, tenofovir, and other renally eliminated drugs and this may increase the risk of adverse reactions. Narcotic Analgesics: methadone ↓ R(–) methadone ↓ S(+) methadone ↔ RPV ↔ methadone (when used with tenofovir) No dosage adjustments are required when initiating coadministration of methadone with ODEFSEY. 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.
