Introduction to Efavirenz, Emtricitabine & Tenofovir Disoproxil Fumarate

Efavirenz, emtricitabine, and tenofovir disoproxil fumarate (EFV/FTC/TDF) are three antiretroviral medicines (ARVs) commonly used as part of a ‘drug cocktail’ to treat people living with HIV. When combined, these drugs help decrease HIV levels in the body, allowing the immune system to fight off the infection. EFV/FTC/TDF is an effective drug combination, and has been approved by the World Health Organization for first-line treatment of HIV. Despite its effectiveness, it is important that users understand both the benefits and risks associated with this medication.

How HIV Works & How Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate (EFV/FTC/TDF) Combats It

HIV is a virus that attacks the immune system and can lead to Acquired Immune Deficiency Syndrome, or AIDS. HIV is contracted through contact with bodily fluids, like blood and semen, or through shared needles or equipment used to inject drugs. Once contracted, HIV slowly weakens the immune system, making the body more vulnerable to infections and other diseases.

Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate (EFV/FTC/TDF) is a medication commonly prescribed as an HIV treatment. It works by blocking the spread of the virus in the body and prevents it from making copies of itself. This helps the body’s immune system remain strong and prevents the virus from progressing further. EFV/FTC/TDF also stops the virus from attaching itself to certain cells, which helps to prevent new infections.

EFV/FTC/TDF is a combination drug, meaning it contains three active ingredients: efavirenz, emtricitabine, and tenofovir disoproxil fumarate. Each one of these components works together to reduce the amount of virus in the body and help keep it under control. Efavirenz works by blocking the replication of the virus in the body, while emtricitabine helps prevent new infections. Tenofovir disoproxil fumarate works by blocking the entry of the virus into healthy cells.

Combining the three medications helps to create a more effective treatment for HIV. EFV/FTC/TDF can help to slow down the progression of the virus, improve quality of life, and reduce the risk of transmitting the virus to others.

Treating for HIV with Efavirenz, Emtricitabine, and Tenofovir Disoproxil Fumarate

Treating HIV with the combination drug Efavirenz, Emtricitabine, and Tenofovir Disoproxil Fumarate (EFV/FTC/TDF) can help lower viral load and reduce the risk of HIV-related illnesses. This course of treatment should be followed closely, with your doctor monitoring your progress.

If you have been diagnosed with HIV, your doctor will likely first perform a physical exam and ask about your symptoms. They will then order laboratory tests, including blood tests and a CD4 count, to determine the stage of your infection and recommend the most appropriate treatment plan.

Your treatment plan might include EFV/FTC/TDF or another combination of antiretroviral drugs. If your virus is resistant to one type of drug, your doctor may prescribe a different combination.

You will likely take the prescribed combination of EFV/FTC/TDF once daily. Your doctor may suggest taking the pills with a meal. It’s important to take them exactly as prescribed and to not skip doses. Missing doses can cause the virus to become resistant to the drugs.

You’ll need to get your blood tested regularly while on EFV/FTC/TDF to make sure the drugs are working. Treatment is successful if the virus is suppressed to undetectable levels. Some people will require adjustments in their medication over time.

Treatment with EFV/FTC is typically long-term. It’s important to stay on the medication even if you feel better, as discontinuing treatment can cause the virus to become resistant again and increase viral load. You should talk to your doctor before stopping treatments or making any changes in dosage.
