PrEP (Pre-Exposure Prophylaxis) is a medication that you can take to prevent you from getting HIV. Taking PrEP means you’re safeguarding yourself against HIV, helping take away the stress of what-ifs or second guesses by reducing your risk of getting HIV from sex.

How does PrEP work?​ 

Taking PrEP consistently and as prescribed means that you can build the medication up in your bloodstream so that, at the time you might be exposed to HIV infection, the medication can effectively stop HIV from making you ill. By taking PrEP, you can give your body an extra layer of protection, because prepping wena means protecting yena. ​
