Pre-exposure prophylaxis refers to preventive medication for people who are not HIV-positive but are considered to be at substantial risk of infection. It involves taking a pill that contains tenofovir and emtricitabine. Daily intake is necessary for the medication to be effective. Pre-exposure prophylaxis is another layer of protection from HIV infection, on top of condoms and other preventive measures.

Tenofovir and emtricitabine are used alongside other drugs to treat HIV infection. As pre-exposure prophylaxis, they work to keep the virus from becoming a full-blown infection. According to studies, when pre-exposure prophylaxis is taken regularly, there is a 92% decrease in the risk of being infected with HIV among people who are highly exposed to the virus. It is less effective when intake is irregular.
