POSSIBLE SIDE EFFECTS OF ATRIPLA

What are the possible side effects of ATRIPLA (efavirenz/emtricitabine/tenofovir disoproxil fumarate)?

ATRIPLA may cause the following serious side effects:

  • Lactic acidosis (buildup of an acid in the blood). Lactic acidosis can be a medical emergency and may need to be treated in the hospital. Call your healthcare provider right away if you get signs of lactic acidosis. (See "What is the most important information I should know about ATRIPLA?" in the Patient Information.)
  • Serious liver problems (hepatotoxicity), with liver enlargement (hepatomegaly) and fat in the liver (steatosis). Call your healthcare provider right away if you get any signs of liver problems. (See “What is the most important information I should know about ATRIPLA?” in the Patient Information.)
  • "Flare-ups" of hepatitis B virus (HBV) infection, in which the disease suddenly returns in a worse way than before, can occur if you have HBV and you stop taking ATRIPLA. Your healthcare provider will monitor your condition for several months after stopping ATRIPLA if you have both HIV-1 and HBV infection and may recommend treatment for your HBV. ATRIPLA is not approved for the treatment of hepatitis B virus infection. If you have advanced liver disease and stop treatment with ATRIPLA, the “flare-up” of hepatitis B may cause your liver function to decline.
  • Serious psychiatric problems. A small number of patients may experience severe depression, strange thoughts, or angry behavior while taking ATRIPLA. Some patients have thoughts of suicide and a few have actually committed suicide. These problems may occur more often in patients who have had mental illness. Contact your healthcare provider right away if you think you are having these psychiatric symptoms, so your healthcare provider can decide if you should continue to take ATRIPLA.
  • Kidney problems (including decline or failure of kidney function). If you have had kidney problems in the past or take other medicines that can cause kidney problems, your healthcare provider should do regular blood tests to check your kidneys. Symptoms that may be related to kidney problems include a high volume of urine, thirst, muscle pain, and muscle weakness.
  • Other serious liver problems. Some patients have experienced serious liver problems including liver failure resulting in transplantation or death. Most of these serious side effects occurred in patients with a chronic liver disease such as hepatitis infection, but there have also been a few reports in patients without any existing liver disease.
  • Changes in bone mineral density (thinning bones). Laboratory tests show changes in the bones of patients treated with tenofovir DF, a component of ATRIPLA. Some HIV patients treated with tenofovir DF developed thinning of the bones (osteopenia) which could lead to fractures. If you have had bone problems in the past, your healthcare provider may need to do tests to check your bone mineral density or may prescribe medicines to help your bone mineral density. Additionally, bone pain and softening of the bone (which may contribute to fractures) may occur as a consequence of kidney problems.

Common side effects:

  • Patients may have dizziness, headache, trouble sleeping, drowsiness, trouble concentrating, and/or unusual dreams during treatment with ATRIPLA (efavirenz/emtricitabine/tenofovir disoproxil fumarate). These side effects may be reduced if you take ATRIPLA at bedtime on an empty stomach. They also tend to go away after you have taken the medicine for a few weeks. If you have these common side effects, such as dizziness, it does not mean that you will also have serious psychiatric problems, such as severe depression, strange thoughts, or angry behavior. Tell your healthcare provider right away if any of these side effects continue or if they bother you. It is possible that these symptoms may be more severe if ATRIPLA is used with alcohol or mood altering (street) drugs.
  • If you are dizzy, have trouble concentrating, or are drowsy, avoid activities that may be dangerous, such as driving or operating machinery.
  • Rash may be common. Rashes usually go away without any change in treatment. In a small number of patients, rash may be serious. If you develop a rash, call your healthcare provider right away. Rash may be a serious problem in some children. Tell your child’s healthcare provider right away if you notice rash or any other side effects while your child is taking ATRIPLA.
  • Other common side effects include tiredness, upset stomach, vomiting, gas, and diarrhea.

Other possible side effects with ATRIPLA:

  • Changes in body fat. Changes in body fat develop in some patients taking anti-HIV-1 medicine. These changes may include an increased amount of fat in the upper back and neck ("buffalo hump"), in the breasts, and around the trunk. Loss of fat from the legs, arms, and face may also happen. The cause and long-term health effects of these fat changes are not known.
  • Skin discoloration (small spots or freckles) may also happen with ATRIPLA.
  • In some patients with advanced HIV infection (AIDS), signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is believed that these symptoms are due to an improvement in the body’s immune response, enabling the body to fight infections that may have been present with no obvious symptoms. If you notice any symptoms of infection, please inform your doctor immediately.
  • Additional side effects are inflammation of the pancreas, allergic reaction (including swelling of the face, lips, tongue, or throat), shortness of breath, pain, stomach pain, weakness, and indigestion.

Tell your healthcare provider or pharmacist if you notice any side effects while taking ATRIPLA.

Contact your healthcare provider before stopping ATRIPLA because of side effects or for any other reason.

Additional IMPORTANT SAFETY INFORMATION for
ATRIPLA (efavirenz/emtricitabine/tenofovir disoproxil fumarate)

Who should not take ATRIPLA (efavirenz/emtricitabine/tenofovir disoproxil fumarate)?

You and your healthcare provider should decide if ATRIPLA is right for you. Do not take ATRIPLA if you are allergic to ATRIPLA or any of its ingredients.

What should I tell my healthcare provider before taking
ATRIPLA (efavirenz/emtricitabine/tenofovir disoproxil fumarate)?

Tell your healthcare provider if you:

  • Are pregnant or planning to become pregnant: Women should not become pregnant while taking ATRIPLA and for 12 weeks after stopping ATRIPLA. Serious birth defects have been seen in children of women treated during pregnancy with one of the medicines in ATRIPLA. Women must use a reliable form of barrier contraception, such as a condom or diaphragm, even if they also use other methods of birth control, while on ATRIPLA and for 12 weeks after stopping ATRIPLA. Women should not rely only on hormone-based birth control, such as pills, injections, or implants, because ATRIPLA may make these contraceptives ineffective.
  • Are breastfeeding: Women with HIV should not breastfeed because they can pass HIV and some of the medicines in ATRIPLA through their milk to the baby. We do not know if ATRIPLA could harm your baby.
  • Have kidney problems or are undergoing kidney dialysis treatment
  • Have bone problems
  • Have liver problems, including hepatitis B or C virus infection. Your healthcare provider may want to do tests to check your liver while you take ATRIPLA or may switch you to another medicine.
  • Have ever had mental illness or are using drugs or alcohol
  • Have ever had seizures or are taking medicine for seizures. Seizures have occurred in patients taking efavirenz, a component of ATRIPLA, generally in those with a history of seizures. If you have ever had seizures, or take medicine for seizures, your healthcare provider may want to switch you to another medicine or monitor you.

What important information should I know about taking other medicines with
ATRIPLA (efavirenz/emtricitabine/tenofovir disoproxil fumarate)?

ATRIPLA may change the effect of other medicines, including the ones for HIV-1, and may cause serious side effects. Your healthcare provider may change your other medicines or change their doses.

MEDICINES YOU SHOULD NOT TAKE WITH ATRIPLA

  • Do not take ATRIPLA if you are taking the following medicines because serious and life-threatening side effects may occur when taken together: Vascor® (bepridil), Propulsid® (cisapride), Versed® (midazolam), Orap® (pimozide), Halcion® (triazolam), or ergot medications (for example, Wigraine® and Cafergot®).
  • ATRIPLA should not be taken with: Combivir® (lamivudine/zidovudine),
    COMPLERA® (emtricitabine/rilpivirine/tenofovir disoproxil fumarate),
    EMTRIVA® (emtricitabine), Epivir® or Epivir-HBV® (lamivudine),
    Epzicom® (abacavir sulfate/lamivudine),
    STRIBILD® (elvitegravir/cobicistat/emtricitabine/tenofovir DF),
    Trizivir® (abacavir sulfate/lamivudine/zidovudine),
    TRUVADA® (emtricitabine/tenofovir DF), or VIREAD® (tenofovir DF), because they contain the same or similar active ingredients as ATRIPLA. ATRIPLA should not be used with
    SUSTIVA® (efavirenz) unless recommended by your healthcare provider.
  • Vfend® (voriconazole) should not be taken with ATRIPLA since it may lose its effect or may increase the chance of having side effects from ATRIPLA.
  • Do not take St. John’s wort (Hypericum perforatum), or products containing St. John’s wort with ATRIPLA. Taking St. John’s wort may decrease ATRIPLA levels and lead to increased viral load, and possible resistance to ATRIPLA or cross-resistance to other anti-HIV-1 drugs.
  • ATRIPLA should not be used with HEPSERA® (adefovir dipivoxil).

These are not all the medicines that may cause problems if you take ATRIPLA. Tell your healthcare provider about all prescription and nonprescription medicines, vitamins, or herbal supplements you are taking or plan to take.
