PEP (Post-Exposure Prophylaxis) is a 28-day course of emergency HIV medication. It must be started within 72 hours of a high-risk exposure (e.g., a condom break with a partner of unknown status), but the sooner you start it, the more effective it is. In the US, access is universal through Emergency Rooms (ER) under federal law, regardless of insurance status.
🚨 Where to Go Right Now
Your route depends entirely on the time of day and your location.
| Time / Day | Where to Go | What to Expect |
|---|---|---|
| Anytime (Everywhere) | Emergency Room (ER) | Go straight to the ER. You will wait, but they will provide the starter pack. |
| Weekday (Daytime) | LGBTQ+ Health Centers or Clinics | Call ahead. E.g., Callen-Lorde (NYC), Fenway Health (Boston), Howard Brown Health (Chicago). |
| Business Hours | Urgent Care / Planned Parenthood | Variable. Call ahead to confirm PEP is available. |
Do not wait for a convenient time. Every hour reduces PEP's effectiveness. Go to the nearest Emergency Room now. Under federal law (EMTALA), ERs must provide emergency medical screening and stabilizing treatment regardless of your insurance status or ability to pay.
🗣️ Navigating Triage
Whether at a clinic or ER, explain the situation clearly.
- At the ER Triage: "I've had a potential HIV exposure and I need PEP — Post-Exposure Prophylaxis."
- With the Doctor: "I need antiretroviral medication started immediately to prevent HIV infection after potential exposure. The 72-hour clock is running." Be specific about the exposure (e.g., receptive anal sex without a condom) to help the doctor assess the risk.
- If there's hesitation (ER): The National Clinician Consultation Center runs a 24/7 PEP line for clinicians: 1-888-448-4911. If the ER physician is uncertain about initiating PEP, give them this number.
The Starter Pack: ERs will issue a starter pack of PEP. The follow-up is mandatory. You must follow up with a specialist clinic or primary care doctor to receive the remainder of the 28-day course and baseline blood tests. Do not miss doses or stop early.
💊 The Medication: What to Expect
The standard US PEP regimen usually consists of Truvada (or generic equivalent) taken alongside an integrase inhibitor like dolutegravir (Tivicay).
- It is a strict regimen: PEP is not a morning-after pill. It is a mandatory 28-day course, and you cannot miss doses.
- Side effects are manageable: You may experience nausea, fatigue, or diarrhea, particularly in the first week. The clinic can prescribe anti-sickness medication.
- Do not stop: Never stop taking PEP without speaking to a doctor first.
💶 Cost
PEP is expensive at list price without assistance, but in practice, most people pay much less or nothing.
- ACA/employer insurance: Covered (may require prior authorisation — ER can initiate starter pack while this is sorted).
- Medicaid: Covered in all states; prior authorisation may apply.
- Uninsured: Gilead's Advancing Access programme (1-800-226-2056) covers Truvada and other ARVs; apply in the ER or immediately after.
- Ryan White ADAP: Available in all states for eligible low-income people.
Federal Law (EMTALA): The Emergency Medical Treatment and Labor Act legally requires every hospital ER to screen and stabilise emergency patients regardless of insurance status or ability to pay. PEP following HIV exposure qualifies. Do not let fear of a bill stop you from going in.
