• Effective against HIV-1 and chronic Hepatitis B virus
• Once-daily dosing improves compliance
• Oral tablet — avoids injections
• Well-studied long-term safety and efficacy
• Lowers viral load, reducing disease progression and transmission risk

1. Take one 300 mg tablet once daily, with or without food. 
2. Swallow the tablet whole with a full glass of water — do not chew or crush.
3. Stick to your dosing schedule consistently — adherence is critical for antiviral effectiveness.
4. Do not stop treatment suddenly, even if you feel better — stopping may lead to resistance or relapse.
5. If you miss a dose, take it as soon as you remember unless the next dose is near; do not double the dose.

Q: What is Tenofo B used for?
A: It’s used to treat chronic hepatitis B and HIV‑1 infection, in conjunction with other antiviral drugs. 

Q: How does it work?
A: It converts into active tenofovir inside the body, which blocks viral reverse transcriptase and prevents viral replication. 

Q: How long before I see effects?
A: Viral suppression usually begins within weeks, but full clinical benefit requires consistent use over months.

Q: What are the common side effects?
A: Side effects may include nausea, headache, kidney problems, and potential bone density issues. 

Q: Can I take this if I have reduced kidney function?
A: Possibly — dose adjustment or careful monitoring may be required, depending on your creatinine clearance.

• Use under a physician’s supervision; typically prescribed in combination with other antivirals. 
• Adjust dose or monitor carefully in patients with renal impairment; tenofovir is excreted via the kidneys. 
• Monitor bone density in long-term use, because tenofovir has been associated with bone mineral loss. 
• Not recommended for patients with severe dehydration or acute renal failure.
• Use with caution in pregnancy or breastfeeding; consult a healthcare provider.
