FDA Hepatitis Update - Changes to label for Atripla (efavirenz/emtricitabine/tenofovir disoproxil fumarate) tablets

FDA recently approved updates to the Atripla (efavirenz/emtricitabine/tenofovir disoproxil fumarate) tablet label to include the following information related to use with hepatitis drugs, boceprevir and telaprevir.
ATRIPLA is a combination of 2 nucleoside analog HIV-1 reverse transcriptase inhibitors and 1 non-nucleoside HIV-1 reverse transcriptase inhibitor, indicated for use alone as a complete regimen or in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults and pediatric patients 12 years of age and older.
Section 12.3 Pharmacokinetics

Boceprevir: Plasma trough concentrations of boceprevir were decreased when boceprevir was coadministered with efavirenz, which may result in loss of therapeutic effect. The combination should be avoided.

Telaprevir: Concomitant administration of telaprevir and efavirenz resulted in reduced steady-state exposures to telaprevir and efavirenz.

Atripla is a product of Gilead Sciences and Bristol-Myers Squibb.
