The combination of efavirenz, emtricitabine, and tenofovir is used alone or along with other medications to treat human immunodeficiency virus (HIV) infection in adults and children weighing more than 40 kg (88 lb). Efavirenz is in a class of medications non-nucleoside reverse transcriptase inhibitors (NNRTIs). Emtricitabine and tenofovir are in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). They work by decreasing the amount of HIV in the body. Although efavirenz, emtricitabine, and tenofovir will not cure HIV, these medications may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other lifestyle changes may decrease the risk of getting or transmitting the HIV virus to other people.

How should this medicine be used?
The combination of efavirenz, emtricitabine, and tenofovir comes as a tablet to take by mouth. It is usually taken once a day with water on an empty stomach (at least 1 hour before or 2 hours after a meal). Take efavirenz, emtricitabine, and tenofovir at around the same time every day. Taking efavirenz emtricitabine, and tenofovir at bedtime may make certain side effects less bothersome. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take efavirenz, emtricitabine, and tenofovir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Continue to take efavirenz, emtricitabine, and tenofovir even if you feel well. Do not stop taking efavirenz, emtricitabine, and tenofovir without talking to your doctor. If you stop taking efavirenz, emtricitabine, and tenofovir even for a short time, or skip doses, the virus may become resistant to medications and may be harder to treat.

Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
