Emtricitabine & Rilpivirine & Tenofovir Overview

Reviewed: September 8, 2012
Updated: 

Emtricitabine/rilpivirine/tenofovir is a prescription medication used to treat HIV (Human Immunodeficiency Virus) which causes acquired immunodeficiency syndrome (AIDs) in adults. It is a single tablet that contains three prescription medicines, emtricitabine, rilpivirine, and tenofovirIn. For HIV to reproduce, it must convert its genetic material from RNA to DNA. These three antiviral medications stop the DNA from being made.

Emtricitabine and tenofovir belong to a group of drugs called nucleoside reverse transcriptase inhibitors (NRTIs). Rilpivirine belongs to a group of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs). NRTIs and NNRTIs work by decreasing the amount of HIV in the blood.

This medication comes in tablet form and is taken once a day, with food.

Common side effects include trouble sleeping (insomnia), abnormal dreams, and headache.

Emtricitabine & Rilpivirine & Tenofovir Precautions

Emtricitabine/rilpivirine/tenofovir can cause serious side effects, including:

Build-up of an acid in your blood (lactic acidosis). Lactic acidosis can happen in some people who take emtricitabine/rilpivirine/tenofovir or similar (nucleoside analogs) medicines. Lactic acidosis is a serious medical emergency that can lead to death. Lactic acidosis can be hard to identify early, because the symptoms could seem like symptoms of other health problems. Call your healthcare provider right away if you get any of the following symptoms which could be signs of lactic acidosis:

  • feeling very weak or tired
  • have unusual (not normal) muscle pain
  • have trouble breathing
  • have stomach pain with nausea or vomiting
  • feel cold, especially in your arms and legs
  • feel dizzy or lightheaded
  • have a fast or irregular heartbeat

Severe liver problems. Severe liver problems can happen in people who take emtricitabine/rilpivirine/tenofovir or similar medicines. In some cases these liver problems can lead to death. Your liver may become large (hepatomegaly) and you may develop fat in your liver (steatosis) when you take emtricitabine/rilpivirine/tenofovir.

Call your healthcare provider right away if you have any of the following symptoms of liver problems:

  • your skin or the white part of your eyes turns yellow (jaundice)
  • dark "tea-colored" urine
  • light-colored bowel movements (stools)
  • loss of appetite for several days or longer
  • nausea
  • stomach pain

You may be more likely to get lactic acidosis or severe liver problems if you are female, very overweight (obese), or have been taking emtricitabine/rilpivirine/tenofovir or a similar medicine containing nucleoside analogs for a long time.

Worsening of Hepatitis B infection. If you also have hepatitis B virus (HBV) infection and you stop taking this medication, your HBV infection may become worse (flare-up). A "flare-up" is when your HBV infection suddenly returns in a worse way than before. Emtricitabine/rilpivirine/tenofovir is not approved for the treatment of HBV, so you must discuss your HBV therapy with your healthcare provider.

New or worse kidney problems can happen in some people who take emtricitabine/rilpivirine/tenofovir.

Depression or mood changes. Tell your healthcare provider right away if you have any of the following symptoms:

  • feeling sad or hopeless
  • feeling anxious or restless
  • have thoughts of hurting yourself (suicide) or have tried to hurt yourself

Bone problems can happen in some people who take emtricitabine/rilpivirine/tenofovir. Bone problems include bone pain, softening or thinning (which may lead to fractures). Your healthcare provider may need to do additional tests to check your bones.

Changes in body fat can happen in people taking HIV medicine. These changes may include increased amount of fat in the upper back and neck ("buffalo hump"), breast, and around the main part of your body (trunk). Loss of fat from the legs, arms and face may also happen. The cause and long term health effect of these conditions are not known.

Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider if you start having new symptoms after starting your HIV medicine.

    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 emtricitabine/rilpivirine/tenofovir, in combination with other antiretrovirals.

    Emtricitabine/rilpivirine/tenofovir is not approved for the treatment of chronic hepatitis B virus (HBV) infection and the safety and efficacy of emtricitabine/rilpivirine/tenofovir have not been established in patients coinfected with HBV and HIV-1.
