Pre-exposure prophylaxis (PrEP) is a medication that can be taken after unprotected encounter with an HIV-positive partner to reduce the risk of HIV infection.
PrEP contains two antiretroviral drugs, tenofovir and emtricitabine, which work together to prevent the virus from establishing itself in the body. The medication is highly effective when taken consistently and as directed, and can reduce the risk of HIV infection by up to 92%.
It is important to note that PrEP is not a cure for HIV, and it is not 100% effective in preventing HIV infection. However, when combined with other preventive measures, such as condom use and regular testing for HIV and other se-ually transmitted infections (STIs), PrEP can significantly reduce the risk of HIV transmission.
To be most effective, PrEP should be taken daily and consistently. If a person misses a dose, the level of protection against HIV may be reduced.
If you have had unprotected encounter with an HIV-positive partner, it is important to seek medical attention as soon as possible. A healthcare provider can evaluate your risk for HIV and discuss whether PrEP is an appropriate option for you. They may also recommend other preventive measures, such as post-exposure prophylaxis (PEP), which is a medication that can be taken up to 72 hours after exposure to HIV to reduce the risk of infection.
It is also important to get tested for HIV and other STIs after unprotected encounter to ensure that you are aware of your status and can receive appropriate treatment if necessary.
In conclusion, PrEP is a medication that can reduce the risk of HIV infection when taken consistently and as directed. If you have had unprotected encounter with an HIV-positive partner, it is important to seek medical attention and discuss the best options for preventing HIV transmission. Regular testing for HIV and other STIs is also essential for maintaining good sexual health.
