Truvada (tenofovir-DF + FTC)
- Truvada is the tradename for a fixed dose combination of tenofovir-DF and FTC.
- In resource-limited countries this is a white tablet with the same design.
- Standard adult dose: 1 tablet (containing 300 mg tenofovir + 200 mg FTC), once-daily.
- Truvada is recommended to be taken with food in Europe and with or without food in the US. Food increases the tenofovir levels in Truvada by about 30%. The benefit of taking tenofovir-DF with food is likely to be more important when first starting treatment, if viral load is very high, or if you have resistance to other nukes.
- Side effects: kidney problems, flatulence (wind), reduced bone mineral density (over first six months).
- Truvada is included with efavirenz in the fixed dose combintion Atripla.
- Other notes: tenofovir is cleared by the kidneys – monitoring for kidney toxicity, and not using tenofovir-DF with other drugs that are cleared the same way, are important safety cautions.
- Truvada is also approved in the US for daily use by HIV negative people as a way to reduce the risk of catching HIV. This way of using HIV drugs is called Pre-Exposure Prophylaxis (PrEP). PrEP need to be prescribed by a doctor.
- The PROUD study in the UK is studying Truvada as PrEP in gay men.
