Doxy PEP’s Impact on STI Rates in San Francisco: A Public Health Breakthrough

It’s a rare bright spot in public health: San Francisco’s STI rates are falling, and fast. Between 2024 and 2025, chlamydia cases dropped 18%, syphilis 24%, and gonorrhea 5%. The numbers aren’t just statistics—they’re real people, fewer of them waking up with that dreaded text from a partner or that awkward clinic visit. And while no single intervention ever works alone, the city’s early embrace of doxy PEP—a post-exposure antibiotic taken after condomless sex—is getting much of the credit. But what does this mean for the rest of us, especially those of us living outside the Bay Area’s progressive health bubbles? If you’re in a city like Austin, where queer communities are vibrant but resources can feel scattered, the story isn’t just about San Francisco’s success. It’s about what happens next: how local clinics adapt, how resistance fears play out, and how individuals navigate a strategy that’s as promising as it is controversial.

Doxy PEP isn’t a magic bullet. It’s a 200mg dose of doxycycline, taken within 72 hours of condomless oral or anal sex, designed to stop chlamydia, syphilis, and—less effectively—gonorrhea in their tracks. For men who have sex with men (MSM) and transgender women who have sex with men, the results are striking: an 88% reduction in chlamydia risk, 87% for syphilis, and 55% for gonorrhea. But for cisgender women, the data is less clear, and the CDC hasn’t yet recommended it for that group. That hasn’t stopped San Francisco from making it a cornerstone of its STI prevention strategy, with clinics like the San Francisco City Clinic and Strut (the city’s LGBTQ+ health hub on Castro Street) offering it alongside PrEP and HIV testing.

Here’s the thing about doxy PEP: it’s not just about the pill. It’s about the infrastructure around it. San Francisco didn’t just hand out antibiotics and hope for the best. The city’s Department of Public Health rolled out a multi-pronged campaign, training providers, launching public awareness efforts in bars and apps like Grindr, and ensuring that doxy PEP was accessible without a prescription at pharmacies like Walgreens and CVS. That last part is key—because if you’re in a city where your local pharmacy still treats STI prevention like a taboo, doxy PEP’s potential shrinks fast. In Austin, for example, where queer health resources are concentrated around the Drag and 4th Street, the question isn’t just whether doxy PEP works. It’s whether the systems are in place to make it work for everyone who needs it.

The Resistance Paradox

For all its promise, doxy PEP comes with a looming shadow: antibiotic resistance. Gonorrhea, in particular, has a long history of outsmarting antibiotics, and there’s concern that widespread doxy PEP employ could accelerate that process. An early study found that certain types of antibiotic-resistant gonorrhea became more common in doxy PEP users, though it’s not yet clear if the strategy is directly to blame. The fear isn’t just theoretical—it’s already happening. In 2023, the CDC reported that gonorrhea’s resistance to azithromycin (another common STI treatment) had jumped to 4.6%, up from 3.6% the year before. If doxycycline follows the same path, the gains we’re seeing now could evaporate.

But here’s the catch: the alternative isn’t great either. Without doxy PEP, STI rates continue to climb, especially in communities already hit hardest by HIV and other health disparities. In San Francisco, the trade-off seems worth it—for now. Dr. Stephanie Cohen, the city’s STI and HIV prevention director, called the drop in cases “remarkable” and credited doxy PEP as a major factor. But she similarly acknowledged the resistance risk, noting that the city is monitoring it closely. That’s the tightrope public health officials everywhere are walking: balancing immediate benefits against long-term risks, all while the bacteria keep evolving.

In Austin, where the University of Texas at Austin’s Dell Medical School has been a leader in HIV and STI research, the conversation is already shifting. Local clinics like Kind Clinic (which serves LGBTQ+ communities) and Austin Public Health’s sexual health programs are watching San Francisco’s data closely, weighing whether to expand doxy PEP access. But they’re also grappling with questions San Francisco hasn’t fully answered yet: How do you scale this without overprescribing? How do you ensure people don’t see it as a replacement for condoms or regular testing? And how do you keep an eye on resistance without stifling innovation?

Beyond the Pill: What’s Next for STI Prevention?

Doxy PEP isn’t the only tool in the toolbox. In fact, it might not even be the most exciting one. Researchers are exploring everything from gonorrhea vaccines (yes, really—studies suggest the meningococcal B vaccine might offer some protection) to long-acting injectables that could prevent STIs for months at a time. But those are years away from widespread use. In the meantime, doxy PEP is filling a critical gap, especially for communities where STIs have been stubbornly high despite other prevention efforts.

Take syphilis, for example. Rates have been climbing nationwide for over a decade, with a 74% increase between 2017 and 2021 alone. In Texas, the numbers are even starker: the state saw a 151% jump in congenital syphilis cases between 2016 and 2020. For queer communities, the stakes are personal. Syphilis can lead to serious complications if left untreated, including neurological damage. Doxy PEP’s 87% reduction in syphilis risk isn’t just a statistic—it’s a potential game-changer for people who’ve spent years navigating a broken system.

But access isn’t just about availability. It’s about trust. In cities like Austin, where queer and trans communities have historically faced discrimination in healthcare, doxy PEP’s success hinges on whether people feel comfortable asking for it. That’s where local organizations come in. Groups like Out Youth and the Texas Health Action’s Kind Clinic aren’t just prescribing doxy PEP—they’re educating, destigmatizing, and making sure people know it’s an option. They’re also addressing the elephant in the room: the cost. While doxycycline is cheap (a month’s supply can cost as little as $10 with insurance), not everyone has insurance. And even with insurance, the cost of a clinic visit or lab tests can add up. San Francisco’s model of making doxy PEP available without a prescription is one way to lower barriers, but it’s not yet the norm in most cities.

What This Means for You: A Local Roadmap

If you’re reading this in Austin—or any other city where doxy PEP is starting to gain traction—you might be wondering what to do next. Should you request your doctor about it? Where can you gain it? And how do you weigh the benefits against the risks? The answers depend on your personal risk factors, your access to healthcare, and your comfort level with antibiotics. But here’s the good news: you don’t have to figure it out alone. Below are three types of local professionals who can help you navigate doxy PEP and other STI prevention strategies, along with what to seem for when choosing them.

1. LGBTQ+-Affirming Sexual Health Providers

Not all doctors are created equal when it comes to STI prevention. If you’re a man who has sex with men, a transgender woman, or part of another group for whom doxy PEP is recommended, you’ll want a provider who’s not just knowledgeable but also affirming of your identity and sexual practices. Look for:

• Specialized training: Providers who’ve completed LGBTQ+ health fellowships or certifications (like those offered by the Gay and Lesbian Medical Association) are more likely to be up-to-date on doxy PEP and other queer-specific health needs.
• Community ties: Clinics that partner with local LGBTQ+ organizations (e.g., Austin’s Out Youth or the Kind Clinic) often have a better understanding of the unique challenges their patients face.
• Non-judgmental approach: A good provider won’t shame you for your sexual activity or make assumptions about your risk level. They’ll ask open-ended questions and tailor their recommendations to your specific needs.

In Austin, some well-regarded options include the Kind Clinic, Austin Public Health’s sexual health clinics, and private practices like Austin LGBTQ+ Center’s health services. If you’re uninsured or underinsured, look for clinics that offer sliding-scale fees or partner with programs like the Texas HIV Medication Program.

2. Infectious Disease Specialists with STI Expertise

If you’re at higher risk for STIs or have a history of antibiotic resistance, an infectious disease specialist can offer a more nuanced approach to doxy PEP. These providers are often on the cutting edge of research and can help you weigh the benefits and risks in a way that a general practitioner might not. Look for:

• Board certification: Ensure they’re certified by the American Board of Internal Medicine in infectious disease.
• Research involvement: Providers who participate in clinical trials or publish research on STIs are more likely to be familiar with the latest data on doxy PEP and resistance patterns.
• Collaborative approach: The best specialists don’t just prescribe—they work with you to create a comprehensive prevention plan, which might include regular testing, PrEP, and condom use.

In Austin, the Dell Medical School at UT Austin has a strong infectious disease program, and many of its faculty see patients at the UT Health Austin clinics. You can also find specialists through the Infectious Diseases Society of America’s provider directory.

3. Pharmacists Who Specialize in Sexual Health

In some cities, you can get doxy PEP without a prescription—directly from a pharmacist. This model, which San Francisco has embraced, lowers barriers to access and can be especially helpful for people who don’t have a regular provider or who face stigma in traditional healthcare settings. But not all pharmacists are comfortable dispensing doxy PEP, and not all pharmacies stock it. Look for:

• Specialized training: Some pharmacists complete additional training in sexual health, such as the American Sexual Health Association’s programs or those offered by state health departments.
• LGBTQ+ competency: Pharmacies that serve large queer communities (e.g., those near Austin’s 4th Street or the Drag) are more likely to be familiar with doxy PEP and other LGBTQ+ health needs.
• Discretion and privacy: A good pharmacist will discuss doxy PEP in a private area of the pharmacy and won’t make assumptions about your sexual activity or identity.

In Austin, some pharmacies to consider include those affiliated with the Kind Clinic or Austin Public Health, as well as independent pharmacies like Tarrytown Pharmacy, which has a reputation for LGBTQ+-friendly care. If you’re unsure whether a pharmacy offers doxy PEP, call ahead and ask if they participate in “pharmacy-initiated doxy PEP” programs.

The Bottom Line

San Francisco’s STI decline isn’t just a local success story—it’s a proof of concept. Doxy PEP works, at least for now, and it’s giving communities a recent way to fight back against an epidemic that’s been raging for decades. But its success depends on more than just the pill. It depends on accessible healthcare, informed providers, and a public health system willing to take risks. In cities like Austin, where the queer community is thriving but resources can feel stretched thin, the challenge is to replicate San Francisco’s model without its advantages: a dense network of LGBTQ+ clinics, a progressive political climate, and a population that’s already engaged in sexual health advocacy.

If you’re considering doxy PEP, start by talking to a provider you trust. Ask about the risks and benefits, and don’t be afraid to shop around if your current doctor isn’t familiar with it. And remember: doxy PEP isn’t a replacement for condoms, regular testing, or open communication with your partners. It’s just one tool in a growing toolbox—and for many people, it’s a tool that’s already making a difference.
