If you may have been exposed to HIV within the last 72 hours, seek medical evaluation now. PEP—post-exposure prophylaxis—is emergency medication used after a potential exposure. CDC recommends starting it as soon as possible, ideally within 24 hours and no later than 72 hours when indicated. The standard course is 28 days. Do not wait until Monday morning, until a telehealth service ships a kit, or until your insurer answers the phone.
The right destination depends on the clock
An emergency department: A practical option when clinics are closed, the exposure may be high risk or you cannot identify an urgent-care provider that evaluates PEP. Tell the triage staff the exposure was recent and you need an urgent assessment for HIV PEP. Do not minimize the time issue because you are embarrassed.
Urgent care: Some centers can evaluate and prescribe PEP, but not all stock or routinely manage the medication. Call only if that will not cause a meaningful delay; ask explicitly, “Can a clinician evaluate HIV PEP today and help me obtain the first dose?” If the answer is uncertain, seek an emergency department.
A sexual-health or HIV clinic: Useful when it is open and can see you immediately. Many are excellent at arranging follow-up and cost assistance. Their office hours, however, may not match the urgency of a late-night exposure.
Telehealth: A legitimate service with a licensed clinician may help in some settings, but an appointment tomorrow cannot replace an assessment today. Oral PrEP signup pages and mailed test kits are generally for prevention before exposure, not a substitute for emergency PEP evaluation.
What to say at check-in
“I may have been exposed to HIV about [number] hours ago. I'd like to be evaluated for HIV post-exposure prophylaxis as soon as possible. I understand there is a 72-hour window. Can you tell the clinician and help me get the first dose if it's recommended?”
Bring the approximate time of exposure, a medication list and any known information about the event if you have it. You do not need to know the other person's HIV status to ask for an evaluation. The clinician evaluates the type of exposure, timing and relevant factors and decides whether PEP is appropriate.
What happens during the visit?
Clinicians generally assess the exposure and order baseline HIV testing and other relevant labs. The CDC's 2025 PEP recommendations say the first dose should not be delayed for pending laboratory results when PEP is indicated. You may receive an initial supply and instructions for completing the course. Ask how you will obtain the remaining medication, whether a pharmacy has it in stock and when follow-up tests and visits should occur.
You may feel overwhelmed, especially after an assault or frightening encounter. You can request privacy, explain safety needs and ask the clinician about additional care. Sexual assault services may provide other medical, forensic and advocacy support according to your wishes and local resources.
What if you cannot afford PEP?
Tell the clinician immediately—before leaving without medication. CDC notes that manufacturer medication-assistance programs may help some uninsured patients and that urgent requests can sometimes be expedited. PEP after workplace exposure may be covered by workers' compensation or employer insurance; assistance related to sexual assault may also exist. Eligibility and billing are different for each situation.
Ask the hospital's financial-assistance team about the emergency visit, not only the prescription. An application that covers medication may not automatically cover the facility bill. See FreePrep's PEP cost guide.
What if it has already been more than 72 hours?
Do not begin leftover PEP medicine on your own. CDC generally does not recommend starting PEP after the 72-hour window, but you should still seek prompt medical advice about testing, follow-up and future prevention. Your clinician can discuss the best plan for your circumstances, including ongoing PrEP if appropriate.
After the urgent visit
Keep the discharge instructions and pharmacy information together. Before leaving, confirm how you will obtain the complete prescribed course, whom to call about side effects and where follow-up testing will happen. If you are likely to need HIV prevention going forward, ask how to transition from PEP to PrEP without an unnecessary gap under clinical supervision.
A practical urgent-care decision chart
If a possible HIV exposure happened within the last 72 hours, seek clinical assessment immediately. An emergency department is an appropriate destination when after-hours services or same-day prescribing are uncertain. Some urgent-care centers and sexual-health clinics also provide PEP, but call to verify that a qualified clinician can evaluate and prescribe it now. Do not spend hours comparing websites, coupons or clinic ratings while the treatment window narrows.
| Situation | Sensible action | Why |
|---|---|---|
| Exposure just occurred | Seek immediate medical evaluation | Earlier initiation is better; CDC says ideally within 24 hours |
| It is the weekend or late night | Use an available emergency department or confirmed open PEP provider | A clinic website's normal business hours may not reflect actual PEP capability |
| You are approaching 72 hours | Tell triage the time of exposure immediately | Delays can affect eligibility and effectiveness |
| More than 72 hours have passed | Seek testing and clinical advice, including future PrEP assessment | CDC generally does not recommend starting nPEP after 72 hours |
| You are unsure whether exposure counts | Tell a clinician what happened, without guessing the risk | The clinical assessment depends on the type of exposure and source information |
What to bring, if it's already at hand
Bring a medication list, allergy information, insurance card if available and the time of possible exposure. Those are helpful, not conditions for being evaluated. It is okay not to know the other person's HIV status. If you were sexually assaulted, ask for trauma-informed care and support; you do not have to decide whether to report the assault before seeking medical attention. Availability and legal requirements differ by location.
Why the first dose should not wait for paperwork
CDC guidance says baseline tests are important but treatment should not be delayed while waiting for laboratory results when PEP is indicated. A clinician can determine the appropriate evaluation and prescription. A website cannot diagnose an exposure, and an at-home HIV test is not a substitute for the clinical workup. If your care site cannot dispense or prescribe PEP promptly, ask where you should go next right away.
Before leaving the clinic: ask three questions
- Medication access: Do I have the prescribed course, or do I need a pharmacy that is actually open and able to fill it?
- Follow-up: Who will contact me about HIV tests, side effects, results and any other needed care?
- Continuity: If future exposures are possible, when will we discuss ongoing PrEP?
PEP courses are typically 28 days. Your clinician should explain follow-up testing and any reasons to return promptly. You should not rely on one immediate negative HIV test as proof that the recent exposure did not lead to infection.
Cost questions to handle without delaying treatment
Once you are being assessed, ask for a social worker, patient navigator, financial counselor or pharmacist who can identify coverage and assistance routes. A hospital emergency-care obligation does not guarantee every visit or medication is free. Private insurance, Medicaid and manufacturer-assistance pathways differ. Keep the discharge paperwork and pharmacy receipts, and request written next steps if you receive only an initial supply.
Frequently asked questions
Can I wait until the next business day?
If waiting would delay evaluation within the 72-hour period, do not wait. Seek an emergency department or another clinician able to evaluate PEP urgently.
Is PEP the same as PrEP?
No. PEP is used after a possible exposure and is time sensitive; PrEP is ongoing prevention before exposure. A person may transition to PrEP after a PEP course under clinical guidance.
Can I get PEP if I don't know the other person's HIV status?
Yes, you can seek evaluation. The clinician assesses the risk and timing rather than requiring you to know the source person's status.
