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 California, access points exist 24/7.

🚨 Where to Go Right Now

Your route depends entirely on the time of day and where you are.

Time / DayWhere to GoWhat to Expect
Weekday Daytime (SF)SF City Clinic or UCSF Ward 86Call ahead. Specialists on site. Full 28-day course available.
Weekday Daytime (LA)LA LGBT Center ClinicSame-day urgent care slots. Call (323) 993-7500.
Evenings / Weekends / AnytimeNearest hospital Emergency RoomState EMTALA law requires ER assessment regardless of insurance.
Anytime (Statewide)PlushCare / MISTR / Nurx (telehealth)Emergency telehealth PEP consultation. Can start a bridge prescription within hours.

Do not wait until Monday. Every hour reduces PEP's effectiveness. If it's a weekend and your clinic is closed, go directly to the nearest hospital ER. California law prohibits ERs from turning away PEP candidates based on inability 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."
  • State the timeline: "The exposure was [X] hours ago. I know I have a 72-hour window."
  • Be direct about the exposure: Explain exactly what happened (e.g., receptive anal sex without a condom) to help the doctor assess the risk. ER triage staff are not always sexual health specialists, so be precise.

The Starter Pack: ERs will typically give you a 3-to-5-day starter supply of PEP. The follow-up is mandatory. You must follow up with a specialist clinic (SF City Clinic, LA LGBT Center, or your primary care doctor) the next business day 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 California PEP regimen is typically Truvada (TDF/FTC) + dolutegravir (Tivicay), or the newer single-tablet combination Dovato.

  • 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. An incomplete course does not protect you.

💶 Cost

  • Medi-Cal: Free.
  • ACA Insurance: Emergency PEP is covered; may have a copay depending on the plan.
  • Uninsured (ER): EMTALA ensures treatment; billing is handled after. Do not let fear of cost stop you. A financial counselor will work with you after treatment begins.
  • Gilead Advancing Access: PEP assistance programme for uninsured patients — request at the clinic.
