Pre-exposure prophylaxis (PrEP) is an HIV prevention strategy in which antiretroviral drugs are used to protect HIV-negative people from HIV infection. PrEP can prevent HIV among individuals at very high risk for becoming infected with HIV, and provides individuals, clinicians, and HIV prevention workers with another option for HIV prevention. When taken consistently, PrEP has been shown to reduce the risk of HIV infection in people who are at high risk by up to 99% according to the CDC.

Providers play an important role in responding to inquiries about PrEP from patients and community members. The resources below provide further information for providers interested in PrEP.
