What is PrEP?

PrEP stands for pre-exposure prophylaxis. It consists of a low-dose of antiretroviral medication. Anyone at high risk of HIV infection is considered a candidate. The dose of this medication is lower than for someone who has confirmed HIV. According to the Centers for Disease Control and Prevention  (CDC), when taken appropriately every day, PrEP can reduce the risk of HIV transmission by 92%.
“PrEP” stands for pre-exposure prophylaxis. "Prophylaxis” means to prevent or control the spread of an infection or disease. The purpose of PrEP is to keep you from becoming infected with HIV in case you are exposed to the virus. PrEP involves taking some of the same medications used for treatment of people who are already living with HIV. You take one pill every day.
