For those who are at high risk for HIV infection, there’s a medical approach that reduces risks of contracting HIV dramatically. It’s called pre-exposure prophylaxis or PrEP. PrEP uses antiretroviral medication (usually Truvada™, a two-drug combination of tenofovir and emtricitabine) to help HIV-negative people stay negative, even if they have sex without a condom with partners whose HIV status is either positive or unknown.
