Drug resistance can be a cause of treatment failure for people living with HIV. As HIV multiplies in the body, it sometimes mutates (changes form) and produces variations of itself. Variations of HIV that develop while a person is taking ART can lead to drug-resistant strains of HIV. With drug resistance, HIV medicines that previously controlled ...
What is drug resistance testing?
Drug-resistance testing identifies which, if any, HIV medicines won’t be effective against your specific strain of HIV. Drug-resistance testing results help determine which HIV medicines to include in an HIV treatment regimen. Taking HIV medication every day, exactly as prescribed helps prevent drug resistance.

[ 13] The AASLD-IDSA HCV Guidance recommends using the same general approach for treating HCV in persons with HCV-HIV coinfection as with HCV monoinfection, but notes the importance of recognizing and managing potential drug interactions between HCV medications and HIV antiretroviral medications. [ 13] In most instances, the AASLD-IDSA HCV Guidance recommends using the same HCV treatment regimens and duration for persons with HCV-HIV coinfection as for those with HCV monoinfection, with several exceptions, as outlined below, that require a longer treatment duration for persons with HCV-HIV coinfection than those with HCV monoinfection due to insufficient data on the efficacy of these 8-week regimens among individuals with coinfection. [ 13]
