Emtricitabine-tenofovir is a combination medication used in the treatment of HIV (human immunodeficiency virus) infection. It combines two antiretroviral drugs, emtricitabine and tenofovir, to suppress the replication of the virus and reduce viral load in the body.

Emtricitabine and tenofovir are both nucleoside reverse transcriptase inhibitors (NRTIs) that target the reverse transcriptase enzyme of the HIV virus. They work by incorporating themselves into the growing viral DNA chain, preventing its further extension and inhibiting viral replication.


This combination therapy is commonly prescribed as part of a comprehensive antiretroviral regimen. It is typically taken orally in the form of tablets. The specific dosage and treatment duration may vary depending on individual factors such as viral load, treatment history, and overall health.

Regular monitoring of viral load and CD4 cell count is important to assess treatment response and adjust therapy if necessary. Adherence to the prescribed dosage is crucial to maintain viral suppression and prevent the development of drug resistance.


Common side effects of emtricitabine-tenofovir may include nausea, diarrhea, headache, and fatigue. These side effects are generally manageable and tend to improve over time. More serious side effects, such as kidney problems or lactic acidosis, are rare but can occur.

It is important to consult with a healthcare professional experienced in the treatment of HIV infection for appropriate guidance and monitoring during therapy. They can provide individualized advice on dosage, potential drug interactions, and other aspects of treatment.


In summary, emtricitabine-tenofovir is a combination medication used in the treatment of HIV infection. It combines two antiretroviral drugs to suppress viral replication and reduce viral load. Adherence to the prescribed regimen and regular monitoring are important for successful treatment outcomes.
