Chlamydia Treatment in Phuket: Confidential Testing and Same-Visit Antibiotics
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Takecare Clinic Phuket. Last reviewed: September 2026.
“Chlamydia is the infection people are most surprised to have, because they feel completely well. We usually find it on a routine screen after a new partner, or because a partner back home has just tested positive and sent a worried message. It is easy to cure. The part that needs planning in Phuket is the antibiotic itself, because doxycycline makes skin burn much faster in the tropical sun.” Dr. Ponlawat Pitsuwan
What chlamydia is and how it spreads
Chlamydia is caused by the bacterium Chlamydia trachomatis. It is passed on through vaginal, anal or oral sex without a condom, and through sharing sex toys. It infects the cervix, urethra (the tube that carries urine out), rectum, throat and occasionally the eyes. WHO describes it as one of the most common bacterial sexually transmitted infections worldwide, and it is most common in people under 25 and anyone with a new partner.
Left untreated, chlamydia can spread upwards. In women it can cause pelvic inflammatory disease (PID), infection of the womb and fallopian tubes that raises the risk of infertility, ectopic pregnancy and long-term pelvic pain. In men it can cause epididymitis, a painful infection of the tube behind the testicle. A rare strain called lymphogranuloma venereum (LGV) causes rectal infection, mainly in men who have sex with men.
Symptoms and look-alikes
Most people with chlamydia have no symptoms at all, which is why testing matters. When symptoms occur, they usually appear 1 to 3 weeks after exposure. Women may notice unusual vaginal discharge, bleeding after sex or between periods, pain during sex, or lower abdominal pain. Men may notice a clear or cloudy discharge from the penis, burning when passing urine, or pain and swelling in a testicle. Discharge and burning in men are signs of urethritis, inflammation of the urethra, and chlamydia is one of its most common causes. Rectal infection can cause discomfort, discharge or bleeding.
Burning when passing urine is also typical of a bladder infection, so we may test your urine for that too; see UTI treatment in Phuket. Gonorrhoea (gonorrhea) causes almost identical symptoms and is tested for from the same sample. In women, a fishy-smelling discharge is more often bacterial vaginosis, which is not an STI and needs different antibiotics, as explained on our BV treatment page.
| Situation | Usual treatment | Retest |
|---|---|---|
| Uncomplicated genital, throat or rectal chlamydia | Doxycycline 100 mg twice daily for 7 days | At 3 months (under 25s and anyone with a new partner) |
| Pregnant or breastfeeding, or cannot take doxycycline | Azithromycin (alternative) | Test of cure about 4 weeks after treatment in pregnancy |
| Rectal infection treated with azithromycin | Doxycycline preferred where possible | Test of cure may be advised |
| Pelvic pain, fever or testicular swelling | Longer, broader antibiotic course (PID or epididymitis) | Review in a few days |
| Current partner of someone with chlamydia | Treated at the same time, ideally after testing | As for the index case |
How we test for and treat chlamydia at Takecare
The test is a nucleic acid amplification test (NAAT), a very sensitive method that detects the bacterium’s genetic material. Men give a first-catch urine sample (the first part of the stream, ideally at least an hour after last passing urine). Women take a quick vaginal swab themselves, which is as accurate as a clinician swab. Throat or rectal swabs are added if you had oral or anal sex. The test is reliable from about 2 weeks after exposure. The doctor tells you when your result will be ready. Testing is discreet and confidential: samples are labelled for the laboratory only, and results are given to you directly.
Current guidelines from CDC and the UK recommend doxycycline 100 mg twice a day for 7 days as first-line treatment, because it cures genital, throat and rectal infections more reliably than a single dose of azithromycin. Azithromycin is the alternative for pregnancy, when doxycycline is not suitable, or when a 7-day course is impractical. If you have symptoms, a positive partner or a high chance of infection, we may start treatment at the same visit, before results return, from our on-site pharmacy. We usually check for gonorrhoea, syphilis and HIV at the same time, as part of full STD testing in Phuket.
Partners, sex and retesting
Anyone you have had sex with in the last 6 months should be told, tested and treated, because they may have no symptoms. If it feels awkward, we can help you word a message. Avoid all sex, including oral sex, until you and your current partners have completed treatment and 7 days have passed. Reinfection from an untreated partner is far more common than treatment failure, so under-25s and anyone with a new partner should test again at 3 months.
When to see a doctor
See a doctor if you have discharge, burning when passing urine, bleeding after sex, pain during sex or testicular pain, or if a partner has tested positive. Come in the same day if you have lower abdominal pain with fever, which may be pelvic inflammatory disease, or a painful, swollen testicle. Sudden, severe testicular pain can be torsion (a twisted testicle) and needs a hospital emergency department immediately. Go to hospital or call 1669 if you have severe one-sided pelvic pain with fainting or bleeding and could be pregnant, which can be an ectopic pregnancy.
Prevention and early detection
Condoms used from start to finish, including for oral sex, greatly reduce the risk of chlamydia. Early detection depends on screening, not symptoms: test after every new partner, and every year if you are under 25 and sexually active. Men who have sex with men with several partners benefit from testing every 3 months, often combined with PrEP reviews at our PrEP clinic in Phuket.

All three branches are open 24 hours a day, 7 days a week, and no appointment is needed. Walk in to Takecare Clinic Bangtao (Cherngtalay), Takecare Clinic Kata-Karon or Takecare Clinic Patong. Most visits take under 30 minutes.
You can message us on WhatsApp first or call 081-718-9080. We confirm the price on WhatsApp before your visit. If you prefer, a doctor can see you at your hotel. We provide direct billing with most travel insurers where the policy covers it, plus itemised receipts and medical reports for claims.
Related services and treatments
A chlamydia diagnosis is a good reason to check for other infections. Our HIV test in Phuket uses a fourth-generation test with results explained in the same visit. Genital blisters or ulcers need herpes treatment rather than antibiotics, and lip blisters triggered by the sun respond to early cold sore treatment. For any other problem during your stay, see a walk-in doctor in Phuket at any branch.
Summary
Chlamydia is common, usually silent and easily cured. A urine test or swab detects it from about 2 weeks after exposure, and 7 days of doxycycline is first-line treatment, with azithromycin as the alternative in pregnancy. Partners need treatment too, sex should wait until 7 days after everyone is treated, and a retest at 3 months catches reinfection. At Takecare Clinic Phuket you can test and start treatment confidentially, at any hour.
“Finish all 14 tablets, keep out of the midday sun while you take them, and make sure your partner is treated too. Do those three things and chlamydia is usually gone for good.” Dr. Ponlawat Pitsuwan
Frequently asked questions
How is chlamydia treated?
First-line treatment is doxycycline 100 mg twice a day for 7 days, which cures most infections. Azithromycin is used as an alternative in pregnancy or when doxycycline is not suitable. Take the full course, avoid sex until 7 days after you and your partners have finished treatment, and retest at 3 months if you are under 25 or have a new partner.
How soon after sex can I test for chlamydia?
The NAAT test is reliable from about 2 weeks after exposure. Testing earlier can miss an infection, so if you test sooner because you have symptoms or a partner tested positive, we may treat you and recommend a repeat test. A urine sample or self-taken vaginal swab is used, with throat or rectal swabs if relevant.
Can I go in the sun while taking doxycycline?
You can, but carefully. Doxycycline makes skin much more sensitive to sunlight, and in Phuket severe sunburn can develop quickly. Use high-factor sunscreen, reapply after swimming, wear a hat and cover up, and avoid the strongest midday sun for the whole 7 days. Tell the doctor if you have a lot of sun planned; azithromycin may be considered.
Does my partner need treatment?
Yes. Anyone you have had sex with in the last 6 months should be tested and treated, even if they feel well, because most people with chlamydia have no symptoms. Treating partners at the same time prevents the infection passing back to you. We can advise on how to tell partners, including those who have already returned home.
Do I need an appointment for chlamydia treatment in Phuket?
No. Walk in to our Bangtao, Kata or Patong branch at any time, day or night, and you are usually seen within minutes. You can also message us on WhatsApp first to confirm the price, or ask a doctor to visit your hotel or villa if you prefer a private consultation.
Will travel insurance pay for chlamydia treatment?
Some travel policies cover the consultation, tests and antibiotics when you have symptoms, while others exclude sexual health. Check your policy wording. We confirm the price on WhatsApp before your visit, provide direct billing with most travel insurers where cover applies, and give you an itemised receipt and medical report for any claim.
