Efavirenz + Emtricitabine + Tenofovir DF Tablet is a once-daily fixed-dose combination used in first-line therapy for HIV-1 infection. It combines the NNRTI efavirenz with two NRTIs—emtricitabine and tenofovir disoproxil fumarate—to interrupt viral replication at multiple enzyme targets.

Mechanism of Action

Efavirenz (NNRTI) binds to and inactivates HIV reverse transcriptase. Emtricitabine and tenofovir (NRTIs) inhibit viral DNA chain elongation by competing with natural nucleotides.

Dosage & Administration

Take one tablet once daily at bedtime on an empty stomach to minimize central nervous system side effects and improve adherence. Swallow whole; do not chew or crush. ([turn0search3], [turn0search16])

Side Effects & Precautions

• Common: dizziness, insomnia, vivid or abnormal dreams, headache, nausea.
• Serious: lactic acidosis, liver toxicity, renal/bone toxicity (from TDF), psychiatric effects.
• Caution: not suitable in pregnancy (EFV is teratogenic), severe renal/hepatic impairment; monitor labs regularly. ([turn0search0], [turn0search4])

Viraday Tablet is a fixed-dose combination of Tenofovir Disoproxil Fumarate (300 mg), Emtricitabine (200 mg), and Efavirenz (600 mg) manufactured by Cipla. It’s used once daily in HIV-1 antiretroviral therapy for viral suppression and immune recovery.

Mechanism of Action

Tenofovir (ntRTI) and Emtricitabine (NRTI) block reverse transcriptase, while Efavirenz (NNRTI) binds non-competitively to the enzyme, inhibiting HIV replication at multiple sites. ([turn0search14])

Usage & Administration

Take one tablet daily on an empty stomach at bedtime. Consistent daily intake is critical to prevent resistance. Avoid crushing or chewing. ([turn0search1], [turn0search3])

Common Side Effects

Possible adverse effects include nausea, dizziness, insomnia, headache, rash, depression, vivid dreams, and fatigue. Monitor psychiatric symptoms and advise caution. ([turn0search1])

Precautions & Warnings

Efavirenz is teratogenic—avoid in pregnancy. Monitor liver and renal function regularly. Do not consume alcohol; caution if underlying psychiatric or hepatic conditions. ([turn0search1], [turn0search2])
