The Post-Exposure Prophylaxis (PEP) HIV treatment method to be effective, it must begin on HIV patient within 72 hours of exposure, before the virus gets time to make too many copies of itself in your body.
The Post-Exposure Prophylaxis (PEP) consists of 2-3 antiretroviral medications and should be taken for 28 days. Your doctors will determine what treatment is right for you based on how you were exposed to HIV.
PEP is safe but may cause side effects like nausea in some people. These side effects can be treated and are not life threatening. The doctors say that PEP is not 100% effective, but it may guarantee that someone exposed to HIV will not become infected with HIV.
