Emtricitabine-Tenofovir Concentrations and Pre-Exposure Prophylaxis Efficacy in Men Who Have Sex with Men.
Peter L. Anderson et al., Sci Transl Med 12 September 2012.
WHAT is PrEP?
Pre-Exposure Prophylaxis (PrEP) is a prescription medicine which helps prevent people from getting infected with HIV. PrEP is a single pill taken once a day that contains the prescription medicines emtricitabine and tenofovir disoproxil fumarate.
WHO should consider PrEP?
Anyone can become infected with HIV. You must be negative for HIV to start PrEP. People who may be at higher risk for HIV infection should consider PrEP.
HOW should PrEP be used?
PrEP reduces, but does not totally eliminate, the risk of HIV transmission. The usual dose of PrEP is 1 pill once a day. While using PrEP, you will need to be tested every 3 months to make sure you remain HIV negative
What are most common SIDE EFFECTS for people using PrEP?
Stomach upset (nausea) can occur and typically goes away after a couple weeks. The medication can cause kidney problems, so we monitor kidney function closely. Other potential side effects include the weakening or softening of bones and liver problems.
How EFFECTIVE is PrEP?
The medication’s effectiveness, or efficacy, depends on how well a person takes the pill each day, which is called medication adherence. For people who take their pills every day, PrEP can significantly reduce their risk of getting HIV. People who take their pills less regularly have less protection against HIV.
