Viread for HIV-1 infection
Quick answer: Viread is used for HIV-1 infection as part of a nucleotide reverse transcriptase inhibitor (ntrti) treatment regimen. Tenofovir disoproxil fumarate inhibits HIV reverse transcriptase and HBV polymerase via competitive incorporation as a chain terminator The specific dosing for HIV-1 infection is determined by your prescriber based on individual factors.
Why is Viread used for HIV-1 infection?
Viread belongs to the Nucleotide reverse transcriptase inhibitor (NtRTI) class. Tenofovir disoproxil fumarate inhibits HIV reverse transcriptase and HBV polymerase via competitive incorporation as a chain terminator This action makes it useful for treating or managing HIV-1 infection in patients for whom this approach is clinically appropriate.
It is one of several treatment options. Whether Viread is the right choice for a specific patient depends on the type and severity of HIV-1 infection, response to previous treatments, individual risk factors, and clinical guidelines.
Typical dosing for HIV-1 infection
Common adult dosing range: 300 mg once daily. The actual dose for HIV-1 infection depends on:
- Severity of the condition
- Patient's age, weight, and organ function
- Other medications being taken
- Treatment response and tolerability
For complete dosing details, see the Viread medicine page.

- Onset of effect: varies by indication and dose — some effects are immediate, others take days to weeks
- Treatment duration: some courses are short-term, others are long-term or lifelong depending on HIV-1 infection
- Monitoring: follow-up visits to assess response and adjust dosing
- Side-effect awareness: learning what to expect and what warrants medical attention
Alternatives to consider
If Viread is not appropriate or not tolerated, alternatives within the same class or different therapeutic classes may be considered. See all Nucleotide reverse transcriptase inhibitor (NtRTI) for related options.
