What is PEP?
Post-Exposure Prophylaxis (PEP) is a four-week course of anti-HIV treatment drugs you can take if you think you may have been exposed to HIV through condomless sex or by sharing injecting drug equipment. PEP can stop HIV from establishing itself in the body and prevent you from becoming HIV-positive if it is taken within 72 hours, ideally as soon as possible after the potential exposure to HIV.
