Description
Generic Name:
Viro 4 Kit Tablet contains Tenofovir Disoproxil Fumarate (300mg) + Lamivudine (300mg) + Atazanavir (300mg) + Ritonavir (100mg), a fixed-dose 4-in-1 combination of two NRTIs and a boosted Protease Inhibitor used in Antiretroviral Therapy (ART) for HIV-1 infection treatment.
Composition:
Each kit contains:
- Tenofovir Disoproxil Fumarate (300mg): NRTI that inhibits reverse transcriptase, blocking HIV-1 DNA formation and preventing viral replication.
- Lamivudine (300mg): NRTI that mimics natural nucleosides to interrupt HIV-1 DNA formation, blocking viral replication.
- Atazanavir (300mg): Protease Inhibitor that blocks the HIV protease enzyme, preventing new virus production.
- Ritonavir (100mg): Pharmacokinetic booster that inhibits CYP3A4 enzyme, increasing Atazanavir blood concentration for stronger HIV-1 suppression.
- Excipients: As per manufacturer’s formulation
Why This Combination is Effective:
The combination of two NRTIs (Tenofovir + Lamivudine) and a boosted Protease Inhibitor (Atazanavir + Ritonavir) offers a triple-target approach — blocking HIV-1 at two separate replication stages simultaneously, making Viro 4 Kit the WHO-recommended regimen for HIV-1 treatment with maximum resistance barrier.
Indication:
Viro4 Kit is indicated for:
- HIV-1 Infection: Used as part of a combination antiretroviral therapy (ART) regimen for the treatment of HIV-1 infection in adults and adolescents.
- Helps in reducing viral load and improving immune system function.
Storage Instructions:
- Store at room temperature (15-30°C).
- Keep in a cool, dry place, away from moisture and direct sunlight.
- Keep out of reach of children.
Uses of the Viro 4 Kit Tablet:
- HIV-1 Infection Treatment: Used as part of Antiretroviral Therapy (ART) to treat HIV-1 infection in adults and paediatric patients — reducing viral load and improving CD4 cell count.
- Second-Line ART Regimen: Used in patients who have failed first-line HIV treatment — the boosted Protease Inhibitor provides a high resistance barrier against HIV-1 drug resistance.
- Prevention of AIDS Progression: Continuously suppresses HIV-1 viral load, preventing HIV from progressing to AIDS and reducing the risk of opportunistic infections.

Viro 4 Kit Tablet is available at TAAL Healthcare at 3,000, making it one of the most affordable 4-in-1 antiretroviral options for HIV-1 treatment in India. Please note that prices may vary depending on pharmacy location and availability.
Benefits of the Viro 4 Kit Tablet:
- Suppresses HIV Viral Load: Blocks HIV-1 at two replication stages — NRTIs + Protease Inhibitor working simultaneously for maximum viral suppression.
- Boosts Immunity: Increases CD4 cell count, reducing risk of opportunistic infections and AIDS complications.
- Once-Daily 4-in-1 Convenience: Single tablet once daily replaces multiple pills — simplifying HIV-1 ART and improving adherence.
- High Resistance Barrier: Triple-target mechanism makes it significantly harder for HIV-1 to develop drug resistance.
- Reduces Transmission Risk: Consistent viral load suppression reduces HIV-1 transmission risk to partners.

How the Viro 4 Kit Tablet Works:
- Blocks Reverse Transcriptase (x2): Tenofovir and Lamivudine both inhibit HIV-1 reverse transcriptase at different points — dual NRTI blockade.
- Blocks HIV Protease Enzyme: Atazanavir prevents HIV-infected cells from assembling new infectious viruses.
- Pharmacokinetic Boosting: Ritonavir inhibits CYP3A4 — increasing Atazanavir blood levels for stronger HIV-1 suppression.
- Reduces Viral Load: 4-drug combination continuously suppresses HIV-1 viral load in the bloodstream.
- Increases CD4 Count: Viral load suppression allows immune system recovery and CD4 cell count increase.
What If You Forget to Take the Viro 4 Kit Tablet?
- Take the missed dose as soon as you remember.
- If it’s close to the next dose, skip the missed dose.
- Do not take a double dose to make up for a missed one.
Best Practices for Adherence to Viro 4 Kit Tablet:
- Take Once Daily with Food: Always take Viro 4 Kit once daily with a meal for better absorption.
- Take at the Same Time Every Day: Consistent timing maintains stable drug levels for maximum HIV-1 suppression.
- Never Skip a Dose: Missing doses increases HIV-1 viral rebound and drug resistance risk.
- Consult Doctor Before Stopping: Never stop Viro 4 Kit without medical advice — abrupt discontinuation causes viral rebound.
Quick Tips:
- Take Viro 4 Kit with food daily to improve Atazanavir and Ritonavir absorption.
- Avoid grapefruit juice, as it interferes with Ritonavir metabolism and treatment effectiveness.
- Regularly monitor liver and kidney function during long-term Viro 4 Kit treatment.
- Do not stop medication without consulting your doctor to avoid viral rebound.
- Avoid alcohol and recreational drugs, as they increase liver toxicity risk.

FAQs:
Q: What is Viro 4 Kit Tablet used for?
A: Viro 4 Kit Tablet is used to treat HIV-1 infection in adults and paediatric patients as part of combination Antiretroviral Therapy (ART). It contains four active ingredients — Tenofovir, Lamivudine, Atazanavir, and Ritonavir — that work together to suppress HIV-1 viral load and improve CD4 cell count.
Q: What is the recommended dosage of Viro 4 Kit Tablet?
A: The recommended dose is one Viro 4 Kit Tablet taken once daily with food. Always follow your doctor’s prescribed dosage — never skip doses as this increases the risk of HIV-1 drug resistance and treatment failure.
Q: Can Viro 4 Kit Tablet cure HIV?
A: No. Viro 4 Kit Tablet does not cure HIV infection. It helps control HIV-1 viral load, improves CD4 cell count, and prevents the disease from progressing to AIDS — but must be taken continuously as prescribed by your doctor.
Q: Can Viro 4 Kit Tablet affect heart rhythm?
A: Yes. Atazanavir in Viro 4 Kit may cause PR or QT prolongation — changes in the heart’s electrical activity. Inform your doctor if you have existing heart conditions or are taking medicines that affect heart rhythm. Seek immediate medical attention if you experience chest pain, fainting, or irregular heartbeat.
Q: Is Viro 4 Kit Tablet safe for kidney disease patients?
A: Viro 4 Kit should be used with caution in patients with kidney disease. Tenofovir Disoproxil Fumarate may affect kidney function with long-term use. Regular kidney function monitoring (creatinine, eGFR) every 3–6 months is recommended during treatment.
Q: Does Viro 4 Kit Tablet interact with other medicines?
A: Yes. Viro 4 Kit has significant drug interactions including:
- Sildenafil (Viagra) — increased risk of severe low blood pressure
- Rifampicin — reduces Atazanavir levels causing treatment failure
- Statins (Lovastatin, Simvastatin) — increased liver damage risk
- Antacids / PPIs — reduce Atazanavir absorption
- St. John’s Wort — reduces ART effectiveness
Always inform your doctor about all medicines and supplements before starting Viro 4 Kit.
Q: How long does Viro 4 Kit Tablet take to work?
A: Viro 4 Kit starts working within a few weeks of starting treatment. Noticeable improvement in HIV-1 viral load typically occurs within 4–8 weeks, with significant CD4 cell count improvement seen within 3–6 months of consistent daily use. Regular viral load and CD4 monitoring confirms treatment effectiveness.
Q: Can I take Viro 4 Kit Tablet during pregnancy?
A: Viro 4 Kit Tablet should be used during pregnancy only if clearly needed and when the benefits outweigh the potential risks. WHO supports the use of Antiretroviral Therapy (ART) in HIV-positive pregnant women to reduce the risk of mother-to-child HIV-1 transmission. However, Atazanavir and Ritonavir in Viro 4 Kit require careful monitoring during pregnancy. Always consult your doctor before starting or continuing Viro 4 Kit during pregnancy — do not self-medicate.
