• Pre-Exposure Prophylaxis PrEP Reduces Risk of HIV Infection

  • Pre-exposure prophylaxis, or PrEP, is a daily pill people who do not have HIV but who are at high risk of getting it can take to prevent HIV infection or becoming HIV positive. The medication works to prevent the virus from developing into a permanent infection in those who are exposed to HIV through sex and/or injection drug use.

    Research shows that people who use PrEP daily are 99% less likely to become infected with the HIV virus through sex. For individuals who inject drugs, PrEP reduces the risk of getting HIV by at least 74% if taken on a daily basis.

    PrEP does not protect against other sexually transmitted infections (STIs).

    KEY THINGS TO REMEMBER

    • Pre-exposure prophylaxis (PrEP) is an antiretroviral drug (ARV) taken daily by HIV-negative people to protect themselves from infection.
    • Evidence shows that PrEP greatly reduces the chances of HIV infection.
    • PrEP’s effectiveness decreases rapidly if not taken regularly as prescribed, so addressing the reasons for non-compliance are key to its success.
    • PrEP does not protect against other sexually transmitted infections. Therefore, other measures need to be taken in order to prevent transmission of other sexually transmitted infections.
