Viraday is a combination medicine used for HIV infection. It contains three antiviral drugs:

• Tenofovir disoproxil fumarate (TDF)

• Emtricitabine (FTC)

• Efavirenz (EFV)

It is usually taken as a single daily tablet.

Mechanism

• Tenofovir and Emtricitabine are nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs). They block the enzyme reverse transcriptase, which HIV needs to make new copies of itself.

• Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It also blocks reverse transcriptase but in a different way.

Together, they reduce the amount of virus in the blood and improve the immune system.

Uses

• Treatment of HIV-1 infection (not a cure, but helps control HIV, improve immunity, and reduce complications).

  Adverse Effects
  Common side effects:

  • Dizziness, headache, trouble sleeping, strange dreams (mainly due to Efavirenz)

  • Nausea, vomiting, diarrhea

  • Tiredness

  • Skin rash
