Vonavir is a medication used in the treatment of HIV (human immunodeficiency virus) infection. It is a combination drug that contains three active ingredients: Emtricitabine (200mg) + Tenofovir disoproxil fumarate (300mg) + Efavirenz (600mg).

Requires Prescription



Here’s information about the use, directions, benefits, mechanism of action, and safety advice related to Vonavir:


  • Vonavir is prescribed for individuals diagnosed with HIV infection.
  • It is used in combination with other antiretroviral medications to suppress viral replication, maintain immune function, and prevent disease progression.
  • Vonavir is generally recommended for adults and adolescents who meet certain criteria determined by a healthcare professional.

Directions of Use:

  • Vonavir is usually taken orally as a tablet.
  • The recommended dosage may vary based on individual factors such as the patient’s weight, renal function, and other medications they may be taking.
  • It is typically taken once daily with food to enhance absorption.
  • Follow the instructions provided by your healthcare professional regarding the timing and administration of Vonavir.


  • Vonavir is an effective antiretroviral medication that helps suppress the HIV virus, reducing its replication and preventing disease progression.
  • By maintaining viral suppression, Vonavir can improve the immune system’s function, reduce the risk of opportunistic infections, and prolong overall health and well-being.

Mechanism of Action:

  • Tenofovir and Emtricitabine belong to a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). They 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 directly inhibits the reverse transcriptase enzyme, further impeding viral replication.

How It Works:

  • Dolutegravir is an integrase inhibitor, which means it works by blocking the action of the integrase enzyme, preventing the integration of the viral DNA into the host cell’s DNA. Tenofovir and Lamivudine are both nucleoside reverse transcriptase inhibitors (NRTIs) that interfere with the reverse transcriptase enzyme, preventing the conversion of viral RNA into DNA. Together, these medications inhibit different stages of the HIV replication cycle, reducing viral replication and the spread of the virus.

Safety Advice:

  • Vonavir should only be taken under the supervision and prescription of a healthcare professional experienced in the treatment of HIV.
  • Inform your healthcare provider about any other medications, supplements, or herbal products you are taking, as they may interact with Vonavir.
  • Attend regular follow-up appointments and medical check-ups to monitor your HIV viral load, CD4 cell count, and overall health.
  • Adhere to the prescribed dosage and maintain consistent use of Vonavir to maximize its effectiveness.
  • Report any side effects or concerns to your healthcare provider promptly.
  • Vonavir may have potential interactions with certain medications, so it's important to inform your healthcare provider about your full medical history and current medications.
  • Take Vonavir with food to improve its absorption and minimize gastrointestinal side effects.
