- HIV is a virus that attacks your body’s immune cells (the cells that work to fight infections).
The 2 medications that make up Truvada (tenofovir and emtricitabine) block important pathways that viruses use to set up infection.
- If you take Truvada as PrEP daily, the presence of the medication in your bloodstream can sometimes stop the virus from establishing itself and slow the spread of HIV in your body.
- By itself, PrEP with Truvada does not work all the time so youshould also use condoms during sex for the most protection from HIV infection.
