Drug-Resistant Gonorrhea in Phuket: Why the Old Antibiotics No Longer Work

Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Takecare Clinic Phuket. Last reviewed: October 2026

You had a night out in Patong. A few days later, discharge. You walked into a pharmacy on Rat-U-Thit Road, pointed at your symptoms, bought a course of azithromycin, and took the whole thing. A week on, something still feels wrong. This is the exact situation I see more often than I should, and the problem is not that you acted. The problem is that the antibiotic you bought probably did nothing useful, and it may have made things harder to treat.

Gonorrhea is now one of the most antibiotic-resistant infections on the planet. Thailand is not behind on this curve. It is near the front of it. And Phuket, with its high tourist turnover, active nightlife in Patong, and easy access to over-the-counter antibiotics, sits at the sharp end of a genuine resistance problem. This is still treatable when done correctly. That last part matters.

Drug-Resistant Gonorrhea Has Already Been Confirmed in Phuket

Most articles on gonorrhea resistance in Thailand cite Bangkok data. But in 2025, a CDC Emerging Infectious Diseases paper confirmed ceftriaxone-resistant gonorrhea at two sites in Thailand. Patong Hospital, Phuket was one of them.

This is not a Bangkok problem that might eventually reach the island. It is already here. The resistance involved a genetic change that makes the bacteria harder to kill even with ceftriaxone, the current first-line injectable antibiotic. I raise this not to alarm you, but because it changes what needs to happen when someone comes in with gonorrhea symptoms after unprotected sex in Phuket.

The Pharmacy Problem: Why Buying Antibiotics in Phuket Makes Resistance Worse

Antibiotics are easy to buy without a prescription at Thai pharmacies. Azithromycin, ciprofloxacin, doxycycline: you can get them across a counter on almost any street in Patong. For tourists, this feels like a practical shortcut. For resistant gonorrhea, it is fuel.

The 2025 CDC paper found that most patients with confirmed ceftriaxone-resistant gonorrhea in Thailand had prior exposure to azithromycin bought without a prescription. That exposure did not cure them. It gave the bacteria a training run. Ciprofloxacin resistance in Thai gonorrhea strains now exceeds 90 percent. Azithromycin resistance is rising fast. Penicillin stopped working years ago.

If you have already taken pharmacy antibiotics and symptoms persist, stop. Do not buy more. Come in for proper testing.

What Happens When Gonorrhea Treatment Fails

Symptoms that return or never fully clear after antibiotics are not always treatment failure. Sometimes it is a co-infection: chlamydia travels with gonorrhea regularly, and a course aimed at gonorrhea may miss it entirely. Sometimes it is reinfection from a partner who was not treated. Sometimes the strain was resistant from the start.

When you come in, I need to know exactly what you took, how much, and for how long. If there is genuine treatment failure, the next step is not another empirical course. It is a culture with antimicrobial susceptibility testing, which tells us which antibiotics your specific strain will actually respond to. Without that test, we are guessing. And guessing with a drug-resistant infection is how complications develop.

Complications from untreated or undertreated gonorrhea include pelvic inflammatory disease in women, epididymitis in men, and in severe cases, infection that spreads to joints and other organs. None of these are outcomes you want to manage in the middle of a Phuket trip.

Why the Type of Gonorrhea Test Matters Here

Most STI testing packages advertised in Phuket use a NAAT test. NAAT is excellent at confirming whether gonorrhea is present. It is fast, accurate, and appropriate for most initial testing. What it cannot tell you is whether your strain is resistant or which antibiotics will work.

For that, you need a gonococcal culture with antimicrobial susceptibility testing. This test guides treatment decisions when standard therapy has already failed. At Takecare Clinic Phuket, the physician assessment determines which test fits your situation, including culture where resistance or treatment failure is a genuine concern. Our STI testing in Phuket is structured around that clinical decision, not a fixed menu.

Throat and Rectal Gonorrhea: The Sites Most Likely to Be Missed

Throat and rectal gonorrhea are both common, frequently produce no symptoms, and are almost never detected by a urine test alone. A urine NAAT will not find gonorrhea in your throat. A swab from the wrong site will miss it entirely.

These sites matter for resistance because the throat is where gonorrhea meets other bacteria and exchanges genetic material, making pharyngeal infection particularly prone to developing resistance. Rectal infections in people of any gender are another site where asymptomatic infection goes untested for longer than it should. If you have had oral or receptive anal sexual contact, a urine sample alone is not enough. Multi-site swabbing is the clinical standard, and a physician assessment determines exactly what you need.

When Gonorrhea Causes No Symptoms at All

Many people with gonorrhea have no symptoms. No discharge. No burning. No pain. This is especially common in women and in throat or rectal infections in anyone. Someone can carry and transmit a drug-resistant strain without any sign that anything is wrong.

In a high-resistance environment like Phuket, waiting for symptoms before testing is not a reliable strategy after potential exposure. If unprotected sex happened during a trip to Patong, Karon, or anywhere else on the island, testing is the right call even if you feel completely fine.

Getting Proper Gonorrhea Treatment in Phuket

The current Thai and WHO first-line treatment for gonorrhea is an intramuscular injection of ceftriaxone, given at a clinic at the correct dose. Not a tablet. Not a course taken at home. An injection, administered correctly, at a clinic. This is not something a pharmacy can provide.

After treatment, a test of cure confirms the infection has cleared. For any case where resistance is a concern, this step is not optional. At Takecare Clinic Phuket in Patong, you can walk in without an appointment, see an English-speaking physician, and get appropriate gonorrhea testing and treatment on the same visit. The clinic serves patients from across the island: Kata, Karon, Rawai, Nai Harn, Chalong, Bang Tao, and beyond. Confidentiality is straightforward at a private walk-in clinic.

Partner notification is also part of the conversation. If your partner has not been tested and treated, reinfection is likely even after successful treatment.

New Gonorrhea Treatments in Development

Zoliflodacin is a new antibiotic in late-stage clinical trials for gonorrhea, with promising early results for resistant strains. It is not yet widely available in Thailand and is not yet standard practice. Current treatment still depends on getting ceftriaxone right, at the correct dose, confirmed by proper testing.

The development pipeline is moving faster than it has in decades, partly because resistance has made gonorrhea a WHO priority pathogen. But the answer right now is not waiting for a new drug. It is using existing treatment correctly, which starts with an accurate diagnosis from a physician who understands what is actually circulating in Phuket.

Can I just buy antibiotics at a pharmacy in Phuket to treat gonorrhea?

You can buy them, but this is one of the main reasons drug-resistant gonorrhea is spreading in Thailand. Surveillance data from 2025 shows most confirmed ceftriaxone-resistant cases involved prior over-the-counter antibiotic use. Without a culture test, there is no way to know whether the strain will respond to what you bought. Come into Takecare Clinic Phuket for a physician assessment and the right test before taking anything.

I took antibiotics for gonorrhea in Phuket but still have symptoms. What should I do?

Do not take more antibiotics without testing first. Persistent symptoms after treatment may mean a resistant strain, a missed co-infection like chlamydia, reinfection from an untreated partner, or an unswabbed site like the throat or rectum. Takecare Clinic Phuket can assess you, swab the right sites, arrange culture and susceptibility testing, and treat you to current Thai and WHO guidelines, with a test of cure follow-up.

Is gonorrhea in Phuket more drug-resistant than in other countries?

Thailand has some of the highest gonorrhea resistance rates documented globally. Ciprofloxacin resistance exceeds 90 percent in Thai surveillance data, azithromycin resistance is rising, and ceftriaxone-resistant strains were confirmed at Patong Hospital in 2025. That combination of high tourist numbers, easy pharmacy access, and long-standing resistance pressure makes Phuket a genuinely elevated-risk environment. Proper testing and treatment at a clinic in Phuket is still effective when done correctly.

What type of gonorrhea test checks for antibiotic resistance?

A standard NAAT test confirms whether gonorrhea is present, but it does not tell you which antibiotics will work. For that, you need a gonococcal culture with antimicrobial susceptibility testing. This is particularly important after treatment failure. At Takecare Clinic Phuket, the physician assessment determines which test is right for your situation, including culture where resistance is a concern.

I feel fine after a night out in Patong. Do I still need to get tested for gonorrhea?

Yes, if there was potential exposure. Gonorrhea is frequently asymptomatic, particularly in women and in throat or rectal infections in anyone. You can carry and transmit a drug-resistant strain without any discharge or discomfort. A urine test alone may miss infection at other sites, so a physician assessment matters even when you feel completely fine.

Does gonorrhea treatment in Phuket require an injection, or can I take tablets?

Current Thai and WHO first-line treatment is an intramuscular injection of ceftriaxone, given at a clinic at the correct dose. Oral antibiotics that used to work, including penicillin, ciprofloxacin, and azithromycin, are no longer reliable for gonorrhea in Thailand. If you were given tablets only, without an injection, your treatment may not meet current guidelines. Come into Takecare Clinic Phuket for review.
