DoxyPEP—taking a 200mg dose of doxycycline within 72 hours of condomless sex—is a proven tool for reducing syphilis and chlamydia transmission. California is one of the best-positioned states in the country to access it. The CDC formally endorsed DoxyPEP guidelines in 2023, and California's LGBTQ+ health centers have integrated it into routine care faster than almost anywhere else.
🏥 Where to Get It
California is ahead of the curve. Unlike many states where DoxyPEP is still navigated around NHS-style institutional hesitance, California's major LGBTQ+ clinics actively prescribe it.
| Provider | Location | Access Route |
|---|---|---|
| SF City Clinic | San Francisco | In-person visit or telehealth. Ask for DoxyPEP protocol during your STI screen. |
| LA LGBT Center | Los Angeles | Available through their sexual health clinic. Ask at your PrEP or STI appointment. |
| Fenway Health (telehealth partner) | Statewide | Remote consultation and prescription. |
| MISTR / Nurx / Folx Health | Statewide (telehealth) | Online consultation, prescription, and home delivery. Most convenient route. |
| Participating pharmacies (SB 159) | Statewide | Some pharmacists can prescribe doxycycline directly. Call ahead to confirm. |
If you're already on PrEP, ask about DoxyPEP at your next quarterly check-in. Most California LGBTQ+ clinics now have a standing protocol for this conversation.
💊 The Dosing Protocol
DoxyPEP is a 200mg single dose within 72 hours of exposure—not a daily pill. You take it after sex, not before. It is not the same as the daily doxycycline used for acne or malaria prophylaxis (which is typically 50–100mg).
The CDC protocol:
- 200mg doxycycline taken within 72 hours of condomless sex
- No more than once every 24 hours
- Not intended as a continuous daily regimen
🦠 What DoxyPEP Covers (and Doesn't)
| STI | Effectiveness |
|---|---|
| Syphilis | ~87% reduction in trials |
| Chlamydia | ~88% reduction in trials |
| Gonorrhea | Modest reduction (gonorrhea's resistance profile limits this) |
| HIV | ❌ No effect. DoxyPEP does not replace PrEP. |
DoxyPEP is not a replacement for PrEP. It provides no HIV protection. If you are using DoxyPEP, you should also discuss whether PrEP is right for you. Both can be used together.
⚖️ Antimicrobial Resistance: The Honest Conversation
California clinicians are generally supportive of DoxyPEP, but responsible prescribers will want a frank discussion about antibiotic stewardship. Regular doxycycline use can shift gut microbiome and may encourage resistance in some bacterial populations.
Your provider may ask about your gonorrhea history, current STI panel results, and overall frequency of sexual exposures before prescribing. This is not gatekeeping—it's good medicine. Be honest about your actual risk profile so they can make the right call with you.
