1. What Are Tenofovir Tablets?

Tenofovir tablets are antiviral medications primarily used to treat HIV-1 infection and chronic hepatitis B. They belong to a class of drugs called nucleotide reverse transcriptase inhibitors (NRTIs). Manufactured under various brand names such as Viread, Tenvir, and Tenohep, Tenofovir disoproxil fumarate (TDF) has become an essential component in antiviral therapy worldwide.

The drug is administered orally, usually once daily, and is often combined with other antiretroviral agents to enhance efficacy. Tenofovir tablets are widely accepted by physicians due to their versatility, excellent tolerability, and reliable results in diverse patient populations, including adults, adolescents, and even children in certain dosing formats.

2. Mechanism of Action: How Tenofovir Works

At the heart of Tenofovir’s success lies its highly targeted mechanism of action. Once ingested, Tenofovir is converted in the body to its active form, tenofovir diphosphate. This compound mimics natural nucleotides, the building blocks of DNA. By inserting itself into the viral DNA chain during replication, Tenofovir effectively halts the replication process, rendering the virus unable to multiply.

What sets Tenofovir apart is its strong binding affinity and low resistance potential, making it a robust choice even in cases where other antivirals may fall short. Its unique mode of action contributes to rapid viral load suppression, particularly in HIV patients starting treatment.

3. Indications: Who Needs Tenofovir?

Tenofovir is prescribed for two major chronic conditions:

• HIV-1 Infection (in adults and adolescents)
• Chronic Hepatitis B (CHB, in adults and children aged ≥2 years)

For people living with HIV, Tenofovir plays a central role in combination therapy regimens, helping reduce viral load to undetectable levels. In hepatitis B, it serves as a monotherapy or combination treatment to reduce liver inflammation and delay disease progression. It is also used as pre-exposure prophylaxis (PrEP) to prevent HIV infection in high-risk populations.

The wide scope of indications, backed by years of clinical endorsement, makes Tenofovir one of the most trusted and frequently prescribed antivirals globally.

4. Dosage and Administration Guidelines

Standard dosing for Tenofovir disoproxil fumarate in adults is 300 mg once daily, taken orally with or without food. In patients with renal impairment, the dose is adjusted based on creatinine clearance levels.

Children with hepatitis B (aged 2 to <12 years) can take Tenofovir in pediatric-specific formulations, ensuring safe and effective dosing.

Administration is convenient and non-intrusive, a major advantage for patients managing chronic conditions. Adherence to the once-daily dosage significantly improves compliance rates, a crucial factor in long-term antiviral success.

5. Clinical Efficacy: What the Studies Show
