Drug-resistant gonorrhea is a growing problem in Thailand, and Pattaya sits at the center of it. Ciprofloxacin no longer works for the vast majority of cases here. Azithromycin is close behind. Ceftriaxone remains the main treatment, but resistant strains were confirmed in Thailand in early 2025. If you bought antibiotics from a pharmacy and still have symptoms, stop and get properly tested before taking anything else.
You recognized the symptoms, walked into a pharmacy on the way back to your hotel, and the pharmacist handed you a box of ciprofloxacin. Seemed reasonable. A week later you still have discharge, burning, or both, and now you are searching for answers. This is one of the most common situations we see at Doctor Pattaya. The answer is not a comfortable one: the antibiotic you took almost certainly did nothing. Gonorrhea in Thailand has been resistant to ciprofloxacin for years.
This is not a scare story. It is a practical briefing on where things stand with drug-resistant gonorrhea in Thailand right now, why the problem is getting worse, and what you should do today if you think you are infected.
How Gonorrhea Beat Every Antibiotic We Threw at It
Gonorrhea has spent decades outpacing the drugs used to treat it. Penicillin was first-line for years. Gonorrhea made it useless. Tetracyclines replaced it. Same result. Fluoroquinolones like ciprofloxacin came next, and for a while they worked well. By the time they were being sold over the counter in Thai pharmacies, resistance in Thailand had already climbed above 90 percent.
Azithromycin followed. Many clinics used it alongside other drugs, and gonorrhea adapted to that too. Then cefixime, an oral antibiotic, started failing at worrying rates across Southeast Asia. Now ceftriaxone, the injectable drug that is currently first-line worldwide, is showing early resistance in Thailand. Confirmed ceftriaxone-resistant strains were isolated here in early 2025. That is a serious escalation, not a theoretical risk.
Understanding why old antibiotics no longer work for gonorrhea helps explain why getting the right test matters as much as getting the right drug.
Why Drug-Resistant Gonorrhea Is a Specific Problem in Pattaya
Thailand is part of WHO’s Enhanced Gonococcal Antimicrobial Surveillance Programme, which tracks resistance patterns across the region. The data consistently places Thailand among the highest-resistance countries in Southeast Asia.
Pattaya’s profile makes this locally relevant in a specific way. High volumes of short-stay tourism, active nightlife, and frequent partner turnover create ideal conditions for gonorrhea to spread fast. When those cases involve drug-resistant strains, they move through the same networks just as quickly. A lot of the patients we see have had multiple partners, treated themselves with pharmacy antibiotics between encounters, and arrived at the clinic weeks later when nothing has cleared. Each round of incomplete or wrong treatment gives the bacteria another chance to adapt.
The Pharmacy Problem — Why Self-Treating Makes This Worse
Thai pharmacies sell antibiotics that require a prescription in most countries. That accessibility is not the problem on its own. The problem is using the wrong antibiotic, at the wrong dose, without ever confirming you actually have gonorrhea and not chlamydia, mycoplasma, or something else entirely.
Ciprofloxacin is the most commonly purchased antibiotic for gonorrhea at Thai pharmacies. Resistance to it here is above 90 percent, meaning nine out of ten cases will not respond to it at all. Azithromycin is the second most common choice, and resistance to that is also high and climbing. Taking either drug against a resistant strain does not just fail to cure you. It exposes the bacteria to partial antibiotic pressure without clearing it, which is exactly how resistance spreads further.
If you self-treated and still have symptoms, do not take more of the same antibiotic. Come in, get a proper test, and find out what you are actually dealing with. Our STD treatment clinic in Pattaya can sort this out without an appointment.
What Changed in 2025 — The Ceftriaxone Situation
For several years, ceftriaxone given by injection was the reliable backstop. Even as other drugs failed, ceftriaxone held. That is still largely true, but the margin is narrowing.
A CDC Emerging Infectious Diseases paper from May 2025 confirmed ceftriaxone-resistant isolates in Thailand, linked to a genetic mutation called the penA-60 allele. Ceftriaxone still works for most infections. Treatment is not impossible. But the window is narrowing, and self-treating with oral antibiotics is exactly what shrinks it faster. The cases where ceftriaxone failed were not random. They were linked to prior incomplete antibiotic exposure.
How We Test for Drug-Resistant Gonorrhea in Pattaya
Most basic clinics run a urine test or swab and tell you whether gonorrhea was detected. That is a NAAT or PCR test, and it confirms infection. What it does not tell you is which antibiotics will actually work on the strain you have.
For that, you need a culture and sensitivity test. We take a swab, grow the bacteria in a lab, and check which antibiotics it responds to. This matters most when you have already self-treated, had symptoms return after treatment, or have any reason to suspect a resistant strain. At Doctor Pattaya, we can arrange both NAAT and culture testing, and the results shape what we prescribe. We do not guess, and we do not reach for a drug with a 90 percent failure rate in Thailand.
Treatment and What Comes After
Current evidence-based treatment is a single dose of ceftriaxone given by injection. For most patients this is straightforward and effective. We check for chlamydia at the same time, because co-infection is common, and treat both where needed.
What many clinics skip is the follow-up. With resistant strains now circulating in Thailand, a repeat test one to two weeks after treatment is genuinely important, especially if you self-treated before coming in. Partner notification matters too. If your partner is still infected, re-infection is possible even after successful treatment on your end.
Doctor Pattaya is open 24 hours, seven days a week, with no appointment needed. If you are staying in Jomtien, Pratumnak, or Naklua, we can send a doctor to your hotel. You do not have to wait until morning.
New Drugs on the Horizon — Zoliflodacin and Gepotidacin
There is some genuinely good news coming. Zoliflodacin is a new antibiotic developed specifically for gonorrhea, and Thailand was one of the clinical trial sites. It works through a different mechanism than existing drugs, which means current resistant strains should still respond to it. Gepotidacin received FDA approval in the United States in 2025 and represents another new option from a different drug class.
Neither is currently standard of care in Thai clinics. But they represent real progress. In the meantime, the most effective thing you can do is get the right diagnosis now, take the right drug at the right dose, and follow up to confirm it worked.
If you have gonorrhea symptoms, think you may have been exposed, or treated yourself with pharmacy antibiotics and are still not better, come in. Doctor Pattaya is open 24 hours a day at our South Pattaya clinic. We offer walk-in STD testing including NAAT and culture and sensitivity testing for suspected resistant gonorrhea, evidence-based treatment, and follow-up care. Hotel visits are available across Pattaya, Jomtien, Pratumnak, and Naklua. No appointment needed.
