Oral PrEP is used by HIV-negative people who are at risk of acquiring HIV before exposure, to reduce their chances of being infected with HIV. Post-Exposure Prophylaxis (PEP) is used by HIV negative people after a possible exposure to HIV and should be started within 72 hours.
One tablet should be taken once daily for at least 7 days before exposure, then taken daily thereafter as long as the risk of HIV infection exists. A different dosing known as event-based oral PrEP is recommended for men. Read more about event-based PrEP in the following link.
