Let's say you had sex with someone who has HIV infection and the condom broke, or you found out only after condomless sex that your partner had HIV. Can you reduce your risk of getting HIV from sex--or from a needlestick--by taking medications afterward? The medications that are given for PEP are the same types that are used to treat HIV antiretrovirals, or ARVs , and they usually are given as a combination of 3 medicines for 1 month. To work best, these ARVs should be taken as soon as possible after the exposure, and ideally not later than 72 hours 3 days after the exposure. To be evaluated for PEP, the exposed individual should contact their clinician or an emergency room promptly after the exposure.

Q: What are the chances of a man being infected after condomless sex with a woman who has HIV? In general, the risk of a man getting HIV from an HIV-positive woman during vaginal intercourse in the United States is low--probably less than 1 of 1, exposures will result in actual infection. This risk may be higher depending on certain factors, such as whether the woman is having her period or whether the man is uncircumcised, and it also may be higher in poor countries. Of course, there is no risk of getting HIV from a woman unless she has HIV, so it's good to talk about this with any potential sex partner.
How Soon After Condomless Sex Should I Get Tested for HIV?
What do the latest studies tell us about this risk? And how should we interpret and communicate the results? It isn't easy for researchers to calculate the risk of transmission from an exposure to HIV through sex. To do this effectively, a group of HIV-negative individuals need to be followed over time and their exposures to HIV -- both the number of times they are exposed and the types of exposure -- need to be tracked.
