PrEP (pre-exposure prophylaxis) is a single daily pill of HIV medication used before possible exposure that provides protection from HIV. The drugs work by stopping HIV from making copies of itself after it enters the body. Proper use of PrEP can provide over 90% protection, when taken every day. For more information visit:

Post-Exposure Prophylaxis

If you’ve been exposed to HIV in the last 72 hours, please visit your primary care provider or another medical provider immediately to start PEP (Post-exposure prophylaxis), a 28 day pill regimen designed to stop HIV from settling inside your body. PEP is for HIV-negative people who may have been exposed to HIV by a needle stick or unprotected sex, and may prevent acquisition of HIV after exposure.

If you live in Seattle-King County and don’t have or cannot access a primary care provider, please visit the Harborview Emergency Room.

What is PrEP?

Pre-exposure prophylaxis (PrEP) is an HIV prevention strategy where HIV-negative individuals take anti-HIV medications before coming into contact with HIV to reduce their risk of becoming infected. The medications work to prevent HIV from establishing infection inside the body.

PrEP has been shown to reduce risk of HIV infection through sex for gay and bisexual men, transgender women, and heterosexual men and women, as well as among people who inject drugs.

It does not protect against other sexually transmitted infections (STI) or pregnancy. It is not a cure for HIV.

Does It Work?

In several studies of PrEP, the risk of getting HIV infection was much lower—up to 92% lower—for those who took the medicines consistently than for those who didn’t take the medicines.

Check out this CDC PrEP page for a brief description of these studies.

Can I Afford It?

The Washington State PrEP DAP , a drug assistance program for HIV-negative people who have risk factors that expose them to HIV, will pay for TRUVADA® for people who want to be on PrEP.

There are some requirements to qualify for the program, such as being HIV-negative, living in Washington State, and being at risk for exposure. Get more details here.
