Efavirenz/Emtricitabine/Tenofovir is a prescription medication that contains three antiretroviral medicines: efavirenz, emtricitabine, and tenofovir. It is used as part of the treatment for human immunodeficiency virus type 1 (HIV-1) infection.

HIV is a virus that attacks the immune system, making it harder for the body to fight infections and certain diseases. Without treatment, HIV can gradually weaken the immune system and progress to acquired immunodeficiency syndrome (AIDS).

Efavirenz/Emtricitabine/Tenofovir belongs to a group of medications called antiretrovirals. These medications work together to reduce the amount of HIV in the body, helping to control the infection and support immune system health.

Treatment of HIV-1 Infection

Efavirenz/Emtricitabine/Tenofovir is used as part of an antiretroviral treatment regimen for adults and certain pediatric patients living with HIV-1 infection.

The medication helps:

  • Lower the amount of HIV in the blood (viral load)
  • Improve immune system function
  • Reduce the risk of HIV-related complications
  • Help prevent disease progression
  • Support long-term management of HIV infection

While this medication helps control HIV, it is not a cure for HIV or AIDS. Continued treatment is necessary to keep the virus under control.

How Efavirenz/Emtricitabine/Tenofovir Works

This medication combines three different antiretroviral agents that work together to prevent HIV from multiplying.

Efavirenz

Efavirenz belongs to a class of medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs). It works by blocking an enzyme called reverse transcriptase, which HIV needs to reproduce.

Emtricitabine and Tenofovir

Emtricitabine and tenofovir belong to a class of medications called nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs). These medications interfere with the virus’s ability to make copies of itself, helping slow the spread of HIV within the body.

Combined Action

By targeting HIV in different ways, the three medications work together to:

  • Reduce viral replication
  • Lower viral load
  • Protect the immune system
  • Help maintain overall health

When taken consistently as prescribed, Efavirenz/Emtricitabine/Tenofovir can be highly effective at controlling HIV infection and helping people live longer, healthier lives.

Efavirenz/Emtricitabine/Tenofovir is available as an oral tablet and should be taken exactly as prescribed by your healthcare provider. The medication is typically taken once daily on an empty stomach, usually at bedtime.

Taking the medication at bedtime may help reduce certain side effects, such as dizziness, drowsiness, or unusual dreams that can occur with efavirenz.

Because this medication contains fixed doses of efavirenz, emtricitabine, and tenofovir, it should only be used under the supervision of a healthcare provider who has determined that the combination and dosage are appropriate for you.

Important Dosing Information

  • Take the medication exactly as prescribed.
  • Take it on an empty stomach unless instructed otherwise by your healthcare provider.
  • Take it at approximately the same time every day.
  • Taking it at bedtime may help reduce certain side effects.
  • Do not take more or less than prescribed.
  • Do not stop taking the medication without first consulting your healthcare provider.

Importance of Taking Every Dose

Consistently taking your HIV medication is essential for keeping the virus under control.

Do not:

  • Skip doses
  • Change your dose
  • Take extra doses
  • Stop treatment without medical advice

Missing doses can allow HIV to multiply, which may:

  • Increase the amount of virus in your body (viral load)
  • Make the infection more difficult to treat
  • Increase the risk of drug resistance
  • Reduce the effectiveness of your HIV treatment

Drug-resistant HIV can limit future treatment options and make long-term management of the infection more challenging.

Ongoing HIV Treatment

Continue taking Efavirenz/Emtricitabine/Tenofovir and any other HIV medications exactly as directed, even if you feel well. HIV treatment is most effective when medications are taken consistently every day.

Regular follow-up appointments, blood tests, and viral load monitoring are important to help ensure your treatment remains safe and effective.

  • Unusual muscle pain or weakness
  • Difficulty breathing
  • Severe tiredness
  • Dizziness
  • Stomach pain
  • Nausea or vomiting

Liver Problems

This medication may cause serious liver problems, including liver damage or, in rare cases, liver failure.

The risk may be higher in people who:

  • Have existing liver disease
  • Have hepatitis B infection
  • Have hepatitis C infection

Contact your healthcare provider immediately if you notice symptoms such as:

  • Yellowing of the skin or eyes (jaundice)

Your healthcare provider may monitor your kidney function with blood and urine tests before and during treatment.

Bone Loss and Fracture Risk

Long-term use of tenofovir has been associated with:

  • Reduced bone mineral density
  • Osteoporosis
  • An increased risk of bone fractures

The risk may be higher in people who already have osteoporosis or other risk factors for bone loss. Your healthcare provider may recommend monitoring bone health during treatment.

Immune Reconstitution Syndrome

As HIV treatment begins to strengthen the immune system, the body may start responding to previously hidden infections. This condition is known as immune reconstitution syndrome or immune reconstitution inflammatory syndrome (IRIS).

Symptoms can vary depending on the infection involved and should be reported to your healthcare provider promptly.

Drug Interactions

Efavirenz/Emtricitabine/Tenofovir can interact with many medications, including:

Tell your healthcare provider if you have:

  • Heart disease
  • High blood pressure
  • High cholesterol
  • Diabetes
  • A history of smoking

Your healthcare provider can help monitor and manage any cardiovascular risk factors during treatment.

Regular follow-up appointments and laboratory monitoring are important while taking Efavirenz/Emtricitabine/Tenofovir to help ensure the medication remains safe and effective.

Is Efavirenz/Emtricitabine/Tenofovir Safe During Pregnancy?

If you are pregnant, planning to become pregnant, or think you may be pregnant, talk to your healthcare provider before taking this medication. Efavirenz/Emtricitabine/Tenofovir may be used during pregnancy when appropriate, and your healthcare provider can help you weigh the potential benefits and risks of treatment. Maintaining effective HIV treatment during pregnancy is important for both maternal health and reducing the risk of HIV transmission to the baby.

Can Efavirenz/Emtricitabine/Tenofovir Cause Liver Damage?

Contact your healthcare provider immediately if you develop symptoms of liver damage, such as yellowing of the skin or eyes (jaundice), dark-colored urine, persistent nausea or vomiting, pain or tenderness in the upper abdomen, or unusual tiredness or weakness. Your healthcare provider may recommend regular blood tests during treatment to monitor your liver function and help detect any problems early.

What Should I Do If I Miss a Dose?

If you miss a dose of Efavirenz/Emtricitabine/Tenofovir, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take two doses at the same time or take extra medication to make up for a missed dose. Missing doses can make HIV more difficult to control and may increase the risk of drug resistance, so it is important to take your medication consistently.

How Long Will I Need to Take Efavirenz/Emtricitabine/Tenofovir?

HIV treatment is usually a long-term commitment. The length of treatment will depend on your individual situation and your healthcare provider’s recommendations.

Alcohol may increase certain side effects of Efavirenz/Emtricitabine/Tenofovir, including dizziness, drowsiness, and difficulty concentrating.
