Answer:
Using HIV Medication to Reduce Risk
It is one of the highly effective options for preventing HIV transmission. People living with HIV who take HIV medication daily as prescribed and get and keep an undetectable viral load have effectively no risk of sexually transmitting HIV to their HIV-negative partners.
PrEP involves taking a pill once daily to prevent HIV infection in someone who is HIV-negative. The pill—approved by the FDA as PrEP in 2012 and marketed under the brand name Truvada—contains a combination of two antiretroviral drugs that stop the virus from reproducing in the body.
