WARNING: LACTIC ACIDOSIS/SEVERE HEPATOMEGALY WITH STEATOSIS and POST TREATMENT EXACERBATION OF HEPATITIS B
See full prescribing information for complete Boxed Warning.
LACTIC ACIDOSIS/SEVERE HEPATOMEGALY WITH STEATOSIS and POST TREATMENT EXACERBATION OF HEPATITIS B: Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs, including tenofovir disoproxil fumarate, a component of efavirenz, emtricitabine, and tenofovir disoproxil fumarate, in combination with other antiretrovirals.
Efavirenz, emtricitabine, and tenofovir disoproxil fumarate is not approved for the treatment of chronic hepatitis B virus (HBV) infection and the safety and efficacy of efavirenz, emtricitabine, and tenofovir disoproxil fumarate have not been established in patients coinfected with HBV and HIV-1. Severe acute exacerbations of hepatitis B have been reported in patients who have discontinued emcitrabine or tenofovir disoproxil fumarate, which are components of efavirenz, emtricitabine, and tenofovir disoproxil fumarate. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who are coinfected with HIV-1 and HBV and discontinue efavirenz, emtricitabine, and tenofovir disoproxil fumarate. If appropriate, initiation of anti-hepatitis B therapy may be warranted.

Overview
Efavirenz, emtricitabine and tenofovir disoproxil fumarate is a human immunodeficiency virus nucleoside analog reverse transcriptase inhibitor, human immunodeficiency virus 1 non-nucleoside analog reverse transcriptase inhibitor that is FDA approved for the treatment of HIV-1 infection. There is a Black Box Warning for this drug as shown here. Common adverse reactions include rash, diarrhea, nausea, decreased bone mineral density, dizziness, headache, anxiety, depression, sleep disorder, increased creatine kinase level, sinusitis, upper respiratory tract infection, fatigue.
Adult Indications and Dosage
FDA-Labeled Indications and Dosage (Adult)
- Adults and pediatric patients 12 years of age and older with body weight at least 40 kg (at least 88 lbs): The dose of efavirenz, emtricitabine and tenofovir disoproxil fumarate is one tablet once daily taken orally on an empty stomach. Dosing at bedtime may improve the tolerability of nervous system symptoms.
- Renal Impairment: Because efavirenz, emtricitabine and tenofovir disoproxil fumarate is a fixed-dose combination, it should not be prescribed for patients requiring dosage adjustment such as those with moderate or severe renal impairment (estimated creatinine clearance below 50 mL/min).
- Rifampin Coadministration: When efavirenz, emtricitabine and tenofovir disoproxil fumarate is administered with rifampin to patients weighing 50 kg or more, an additional 200 mg/day of efavirenz is recommended
