Pre-Exposure Prophylaxis (PrEP)

Pre-Exposure Prophylaxis (PrEP)

Pre-exposure prophylaxis (PrEP) is the use of medications to prevent the spread of disease in people who have not yet been exposed to a disease-causing agent, usually a virus. The term typically refers to the use of antiviral drugs as a strategy for the prevention of HIV/AIDS. PrEP is one of a number of HIV prevention strategies for people who are HIV negative but who have a higher risk of acquiring HIV, including sexually active adults at increased risk of contracting HIV, people who engage in intravenous drug use (see drug injection), and serodiscordant sexually active couples.

When used as directed, PrEP has been shown to be highly effective, reducing the risk of acquiring HIV by up to 99%.
