If you have just experienced a potential exposure to HIV, you likely have many questions about what to do next. We are here to provide clear, calm information to help you manage your health.
What we’ll cover:
The moment you realize you may have been exposed to HIV, your mind races. Whatever brought you here, you may feel scared, unsure, or overwhelmed.
We want you to know right away: you have more control over this situation than you might think.
The first 72 hours after a potential exposure represent a window, not a guarantee of infection, but an opportunity to act. What you do in this timeframe can genuinely change your outcome.
This isn't about panic. It is about information and access. Understanding what to do after possible HIV exposure can transform a frightening moment into a manageable one.
You do not have to figure this out alone.
According to the CDC, HIV takes time to establish an infection after exposure. This is because after the virus enters your system, it takes time to begin replicating and integrating into your cells. This delay creates a narrow but meaningful window for medical intervention.
Within the first 72 hours, a medication called PEP (post-exposure prophylaxis) can potentially stop HIV from taking hold. PEP is not recommended after 72 hours, as it is unlikely to be effective.
PEP works best when started as soon as possible, ideally within 24 hours.
Before you do anything else, take a moment to steady yourself. Fear is a reasonable response, but you need clarity to make good decisions right now.
Understanding your actual risk level helps us determine the right response. Not every exposure requires PEP, but many do, and the only way to know for sure is to talk with a professional who can evaluate your specific situation.
Your goal is to see a healthcare provider who can assess your exposure and prescribe PEP if it is needed.
Options include:
When you call, be direct. Say you may have been exposed to HIV and need to discuss PEP. This helps staff prioritize your visit.
Do not let cost or insurance concerns hold you back. We work with patients to find solutions.
The initial test is not looking for the new exposure; it takes weeks for HIV to show up on most tests. Instead, we test to see if you already have HIV from a previous exposure. This matters because PEP is only for people who are currently HIV-negative.
You will also likely be screened for other sexually transmitted infections (STIs), as treating them is part of your whole-person care.
As mentioned before, PEP stands for post-exposure prophylaxis. "Prophylaxis" simply means prevention.
PEP is a 28-day course of medication taken after a potential HIV exposure to prevent the virus from establishing infection.
The medications in PEP are the same drugs used to treat HIV in people already living with the virus. When taken shortly after exposure, these medications can help stop HIV from establishing an infection.
You can learn more about the process on our PEP information page.
Managing your health is about more than just medicine. Potential exposure can affect your mental health and sense of stability.
That’s why we believe in a whole-person approach that supports your entire well-being.
We are here to help you move forward with clear support. We help more people access life-saving care by connecting you with counseling to process the emotional impact of this moment.
Our goal is to provide a safe, private space where you can discuss these concerns without fear of stigma or judgment.
We’re a community clinic built to support your care, your stability, and your next steps.
If you cannot get a same-day clinic appointment, an urgent care center or emergency room may be the right place to ask about PEP. The most important thing is to speak with a healthcare provider as soon as possible within the 72-hour window.
Yes, potentially. PEP (post-exposure prophylaxis) is a 28-day medication regimen that can prevent HIV infection when started within 72 hours of exposure. The earlier PEP begins, the more effective it is. While not 100% guaranteed, it significantly reduces the likelihood of HIV transmission when taken correctly.
HIV can begin establishing infection in the body within days after exposure. That is why PEP must be started within 72 hours, and sooner is better. Intervention during this period can disrupt the virus before the infection becomes fully established.
PEP should be started within 72 hours (three days) of possible HIV exposure. The medication is generally not effective after this point. If you are unsure if you are still within the window, contact a healthcare provider immediately. The sooner you reach out, the better.
A potential exposure is a stressful event, but it does not define your future. With the right care and early intervention, you can take the next step to protect your health.
