What does Truvada do to your body?
Both medicines inside Truvada interfere with an enzyme called reverse transcriptase, which is used by HIV-infected cells to make new viruses. Since Truvada reduces the activity of reverse transcriptase, it causes HIV-infected cells to slow down or stop producing new viruses.
Does Truvada make you gain weight?
Because people taking Truvada decreased their weight by -0.1% at week 24 in the iPrEx study, and showed less weight gain than people taking placebo at weeks 48 and 72, Truvada may initially prevent normal weight gain but, according to this study, this effect may fade with long-term use.
