What PrEP: prevention before exposure means for you

PrEP is medicine for people without HIV that greatly reduces the chance of getting HIV when taken as prescribed. That short answer is the place to begin; what matters next is how it fits your situation—your reason for reading, the timing of any event, and the support you can reach. Treat this guide as a map: it can help you prepare and ask better questions, while a qualified health professional applies the details to you.

02

The essentials for PrEP: prevention before exposure

Prevention combines tools: PrEP before a possible exposure, PEP as an emergency within 72 hours, condoms with compatible lubricant, sterile injection equipment, and testing. Someone on treatment with an undetectable viral load does not pass HIV on through sex (U=U). Each option has its own follow-up, and a clinician can help combine them—one method does not have to replace the others.

03

Turn it into one next step

You do not need perfect medical words. Note any relevant dates, test names, or medicines, then choose one manageable action. For this page, a useful next step is find prep support—a suggestion, not a rule. If it feels too big, make it smaller: save a phone number, check opening hours, or tell someone you trust. The plan can change as a result or new information arrives.
