How does it work?

It works to reduce the risk of HIV. When it is taken before exposure to HIV, it means that there is enough of the drug inside you to block HIV if it enters your body. The ingredients tenofovir and emtricitabine are drugs commonly used to treat HIV.

Additional Information

When taken consistently and correctly, PrEP has been shown to reduce the risk of HIV transmission by up to 92%. However, PrEP is not 100% effective, so it should be used in combination with other prevention methods such as condoms.

If you think you might be at risk for HIV infection, talk to your healthcare provider about whether PrEP is right for you.

Pre-exposure prophylaxis (PrEP) is a way for people who do not have HIV but who are at substantial risk of getting it to prevent HIV infection by taking a pill every day. The pill (brand name Truvada) contains two medicines (tenofovir and emtricitabine) that are used in combination with other medicines to treat HIV. PrEP can stop HIV from taking hold and spreading throughout your body. It is very important to understand that PrEP is not a vaccine and it will not protect you from other sexually transmitted infections (STIs). You should still use condoms the right way every time you have sex.

PrEP is approved by the U.S. Food and Drug Administration (FDA) for people at risk of getting HIV through sex, including men who have sex with men and people who are in an on-going relationship with an HIV-positive partner. PrEP is also approved for people who inject drugs. Clinical trials have shown that when taken every day, PrEP reduces the risk of getting HIV from sex by about 99%. Among people who inject drugs, PrEP reduces the risk of getting HIV by at least 74%.

PrEP must be taken every day, preferably at the same time each day, to work. If you take it consistently, your risk of getting HIV will be much lower than if you do not take PrEP. However, if you do not take PrEP every day, it will not work as well. If you start taking PrEP and then stop, your risk of getting HIV will go back up.

You should talk to your health care provider about whether PrEP is right for you.

PrEP is not for everyone. If you think PrEP might be right for you, talk to your health care provider about whether you should start taking it. You will need to have an HIV test before you start taking PrEP and every 3 months while you are taking it to make sure that you do not have HIV. If you start taking PrEP and then test positive for HIV, you will need to stop taking PrEP and start antiretroviral therapy (ART) right away.

If you are prescribed PrEP, you will also need to see your health care provider every 3 months for follow-up visits.
