If a condom breaks and you know you had sex with someone who is living with HIV, you will need to visit a healthcare professional as soon as you can. You may be offered post-exposure prophylaxis (PEP) treatment.6 This is a month-long treatment of antiretroviral drugs (ARVs) that can reduce the risk of HIV establishing in your body. PEP has a high success rate; but, it is not a replacement for condoms. PEP is a powerful drug that has side effects and not everyone can have the treatment.
