Requires Prescription



Here is some information about its use, directions, benefits,
how it works, and safety advice:


  • Tenofovir/lamivudine/efavirenz is used for the management of HIV-1 infection in adults and adolescents. It is prescribed as part of a combination therapy regimen, typically along with other antiretroviral drugs.

Directions of Use:

  • The dosage and administration instructions for Tenofovir/lamivudine/efavirenz may vary depending on factors such as your age, weight, other medications you are taking, and your specific HIV treatment history. It is important to follow the instructions provided by your healthcare provider and the information on the medication label. Tenofovir/lamivudine/efavirenz is usually taken orally once daily on an empty stomach, preferably at bedtime.


  • Tenofovir/lamivudine/efavirenz is highly effective in suppressing the replication of the HIV virus. It helps reduce the viral load, increase CD4 cell counts, and improve immune function. By consistently taking Tenofovir/lamivudine/efavirenz as prescribed, individuals with HIV can achieve and maintain viral suppression, leading to improved health outcomes and a reduced risk of transmitting the virus to others.

How It Works:

  • Tenofovir/lamivudine/efavirenz is a combination of three different antiretroviral drugs. Tenofovir and lamivudine are nucleoside reverse transcriptase inhibitors (NRTIs) that work by inhibiting the reverse transcriptase enzyme, which is essential for the replication of the HIV virus. Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that works by binding to and inhibiting the reverse transcriptase enzyme. By blocking this enzyme, the medication prevents the conversion of viral RNA into viral DNA, thereby inhibiting viral replication.

Safety Advice:

  • It is important to take Tenofovir/lamivudine/efavirenz consistently and as prescribed by your healthcare provider. Adherence to the treatment regimen is crucial for its effectiveness. Inform your healthcare provider about any other medications you are taking, including over-the- counter drugs and supplements, as there may be potential drug interactions. Common side effects of
    Tenofovir/lamivudine/efavirenz may include dizziness, drowsiness, nausea, diarrhea, and rash. However, not everyone experiences these side effects. It is important to report any concerning or persistent side effects to your healthcare provider. Regular monitoring of liver function, kidney function, and HIV viral load is typically recommended during treatment.

Please note that the information provided here is a general overview, and it is important to consult with your healthcare provider for personalized guidance and specific instructions related to your HIV treatment. They will be able to provide you with the most accurate and up-to-date information based on your individual needs and medical history.
