What is tenofovir 300 mg, and what is it used for?
“Tenofovir 300 mg” usually refers to the dose strength of tenofovir disoproxil fumarate (TDF) tablets used in HIV treatment and HIV pre-exposure options in some settings. Tenofovir is a nucleotide reverse transcriptase inhibitor used to block HIV replication.
If you meant a specific product, the exact indication and dosing schedule can depend on whether it is TDF (tenofovir disoproxil fumarate 300 mg) or tenofovir alafenamide (TAF) (which has different tablet strengths and dosing).
Tenofovir 300 mg vs TAF: what’s the difference?
The “300 mg” strength typically points to TDF, while TAF is a different prodrug form with different dosing (commonly smaller mg per tablet) and a different side-effect profile. The choice between them is often driven by kidney function and bone health risk.
How do people take tenofovir 300 mg (once vs twice daily)?
For many HIV regimens that include tenofovir disoproxil fumarate 300 mg, dosing is commonly once daily, but the exact schedule depends on:
- which fixed-dose combination tablet it’s in (if any),
- the rest of the regimen,
- kidney function, and
- the clinical goal (treatment vs prevention).
What side effects are associated with tenofovir 300 mg?
Common concerns with tenofovir-based therapy include:
- kidney effects (kidney function monitoring is typical),
- bone-related effects (bone mineral density considerations),
- GI effects (nausea, diarrhea) in some patients.
Your clinician may adjust dosing or switch formulations if kidney function changes.
Does tenofovir 300 mg need dose adjustment for kidney problems?
Yes, kidney function often determines whether tenofovir disoproxil fumarate 300 mg is safe at standard dosing, and whether dose changes or a different formulation is needed. Clinicians typically monitor serum creatinine/eGFR and urine tests where appropriate.
Is tenofovir 300 mg covered by patents or exclusivity?
