Generic Name: efavirenz/emtricitabine/tenofovir (EF-a-VIR-enz/EM-trye-SYE-ta-been/ten-OF-oh-vir)
Brand Name: Atripla

Severe and sometimes fatal lactic acidosis (a buildup of lactic acid in the blood) and liver problems have occurred with tenofovir, which is part of Atripla. The risk may be greater in women, patients who are very overweight, or patients who have been taking nucleoside medicines (eg, emtricitabine, tenofovir) for a long time.

Tell your doctor right away if you develop symptoms of lactic acidosis (eg, unusual weakness or tiredness; unusual muscle pain; fast or difficult breathing; stomach pain with nausea and vomiting; feeling cold, especially in the arms and legs; dizziness or light-headedness; fast or irregular heartbeat). Tell your doctor right away if you develop symptoms of liver problems (eg, yellowing of the skin or eyes, dark urine, pale stools, persistent loss of appetite, nausea, stomach pain).

Atripla is not approved to treat hepatitis B virus (HBV) infection. Safety and effectiveness have not been confirmed in patients who have both HIV and HBV infection. Some patients with HBV infection who took emtricitabine or tenofovir have had severe worsening of HBV infection after they stopped taking them. Patients with both HIV and HBV who take Atripla should have medical exams and liver function tests performed for at least several months after they stop taking Atripla. Keep all doctor and lab appointments. Do not stop taking Atripla without checking with your doctor.


Atripla is used for:

How to use Atripla:

Use Atripla as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • An extra patient leaflet is available with Atripla. Talk to your pharmacist if you have questions about this information.

Ask your health care provider any questions you may have about how to use Atripla.

Important safety information:

  • Atripla may cause drowsiness, dizziness, or trouble concentrating. These effects may be worse if you take it with alcohol or certain medicines. Use Atripla with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
  • Check with your doctor before you drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Atripla; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
  • Atripla may cause dizziness, drowsiness, trouble sleeping, trouble concentrating, or unusual dreams. These effects usually go away after you have taken Atripla for about 2 to 4 weeks. Taking it at bedtime may help make these effects less bothersome. Check with your doctor if they continue or are severe.
  • Do NOT take more than the recommended dose, change your dose, or stop taking Atripla without checking with your doctor. Taking more than the recommended dose may not provide additional benefits and may increase the risk of side effects.
  • You should be tested for HBV infection before you start to take Atripla.
  • Tell your doctor or dentist that you take Atripla before you receive any medical or dental care, emergency care, or surgery.
  • Keep a list of all the medicines that you take. Make a new list each time medicines are added or stopped. Find out about medicines that should not be taken while you are using Atripla. Be sure that each of your health care providers knows all the medicines that you are taking.
  • Atripla is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.
  • Atripla does not stop the spread of HIV to others through blood or sexual contact. Do not have any kind of sex without protection (eg, latex or polyurethane condoms) if you have HIV infection. Do not share needles, injection supplies, or items such as toothbrushes or razors. Talk with your health care provider about ways to prevent the spread of HIV to others.
  • When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking Atripla, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.
  • Changes in body fat (eg, an increased amount of fat in the upper back, neck, breast, and trunk, and loss of fat from the legs, arms, and face) may occur in some patients taking Atripla. The cause and long-term effects of these changes are unknown. Discuss any concerns with your doctor.
  • Atripla may improve immune system function. This may reveal hidden infections in some patients. Tell your doctor right away if you notice symptoms of infection (eg, fever, sore throat, weakness, cough, shortness of breath) after you start Atripla.
  • Check with your doctor to see if you should take a calcium and vitamin D supplement while you are taking Atripla.
  • Women who may become pregnant should have a negative pregnancy test before they start to take Atripla. Discuss any questions or concerns with your doctor.
  • If you may become pregnant, you must use an effective form of birth control while you take Atripla and for 12 weeks after you stop taking it. Hormonal birth control (eg, birth control pills) may not work as well while you are using Atripla. You should always use a barrier form of birth control (eg, condoms), even if you already use another method of birth control (eg, hormonal birth control). If you have questions about effective birth control, talk with your doctor.
  • Atripla may affect certain lab tests, including drug tests. Be sure your doctor and lab personnel know you are taking Atripla.
  • Lab tests, including liver and kidney function, cholesterol and triglyceride levels, and bone density, may be performed while you use Atripla. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Atripla should not be used in CHILDREN younger than 12 years old; the doses needed for these children cannot be made with Atripla.
  • PREGNANCY and BREAST-FEEDING: Atripla may cause harm to the fetus. Do not become pregnant while you take Atripla and for 12 weeks after you stop taking it. If you think you may be pregnant, contact your doctor right away. Atripla is found in breast milk. Do not breast-feed while taking Atripla. Mothers infected with HIV should not breast-feed. There is a risk of passing the HIV infection or Atripla to the baby.
