Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Stribild (elvitegravir/cobicistat/emtricitabine/tenofovir) and Efavirenz (Sustiva) are both used to treat HIV, but they have some key differences. Stribild is a combination of four medications, including an integrase inhibitor, two nucleoside reverse transcriptase inhibitors (NRTIs), and a booster, and it is taken once daily with food. In contrast, Efavirenz (Sustiva) is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that must be taken on an empty stomach at bedtime. Stribild is a single-tablet regimen, while Efavirenz (Sustiva) is taken with other antiretrovirals. Efavirenz (Sustiva) is available in generic form, making it a lower-cost option, whereas Stribild does not have a generic version. Both medications have significant side effects and interactions, but Efavirenz (Sustiva) is particularly noted for causing nerve issues and mood changes, while Stribild can cause kidney and bone problems. Neither medication is recommended during pregnancy, but Stribild is also not suitable for those with kidney or liver issues.
