You might have heard of both PrEP and PEP, they sound similar, but they’re used in different situations. Knowing the difference can help you choose the right protection when you need it.
What is PrEP?
PrEP (Pre-Exposure Prophylaxis) is taken before any potential exposure to HIV.
It’s a daily pill that helps prevent HIV before it enters your body. If you’re regularly at risk or just want ongoing protection, PrEP is the option for you.
👉 Think of PrEP as prevention before anything happens.
What is PEP?
PEP (Post-Exposure Prophylaxis) is taken after a possible exposure to HIV.
For example, if you had unprotected sex or something unexpected happened, PEP can help reduce the risk of infection, but timing is very important.
👉 You must start PEP within 72 hours (3 days) of exposure for it to work.
PEP is taken for 28 days and is meant for emergency situations, not regular use.
