Pre-Exposure Prophylaxis (PrEP)
Pre-exposure prophylaxis (PrEP) is medicine that can be taken to reduce a person's chances of getting HIV from sex or sharing drug injection equipment. PrEP is for people who do not have HIV but have the chance of getting it. When someone taking PrEP is exposed to HIV through sex or sharing drug injection equipment, the medicines can keep the virus from establishing a permanent infection. Taking PrEP as prescribed by a health care provider can reduce the chances of getting HIV by up to 99% from sex and by at least 74% from sharing drug injection equipment.
Medication also can be taken following a possible exposure to HIV to help prevent transmission of the virus. In such cases, the medications are referred to as post-exposure prophylaxis (PEP). Both PrEP and PEP can be prescribed by a doctor, physician assistant or nurse practitioner.
