BV Treatment in Phuket: Bacterial Vaginosis Diagnosis and Same-Visit Antibiotics
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Takecare Clinic Phuket. Last reviewed: September 2026.
“Many women who come to us with discharge on holiday have already tried a thrush cream from a pharmacy, and it has not helped. That is often because the problem is BV, not thrush. Heat, damp swimwear, a new partner and a change in routine can all tip the vaginal balance. A short examination and a couple of simple tests usually tell us which it is, and the right treatment works quickly.” Dr. Ponlawat Pitsuwan
What bacterial vaginosis is and what causes it
The vagina normally contains lots of protective bacteria called lactobacilli, which keep it slightly acidic. In bacterial vaginosis, the number of lactobacilli falls and other bacteria, such as Gardnerella vaginalis, overgrow. The vagina becomes less acidic, and the bacteria produce the chemicals that cause the typical smell.
BV is the most common cause of abnormal vaginal discharge in women of reproductive age. It is not classed as a sexually transmitted infection, and women who have never had sex can get it, but it is linked to sexual activity: a new partner, several partners, and sex between women all raise the risk. Other triggers include douching, perfumed soaps and bubble baths, vaginal deodorants, a copper coil (IUD) and smoking.
Symptoms, and how to tell BV from thrush and trichomoniasis
The main symptom is a thin, watery, grey or white discharge with a strong fishy smell, often more noticeable after sex or during a period. BV does not usually cause itching or soreness. About half of women with BV have no symptoms at all.
| Feature | Bacterial vaginosis | Thrush (candida) | Trichomoniasis |
|---|---|---|---|
| Discharge | Thin, watery, grey-white | Thick, white, like cottage cheese | Frothy, yellow-green, may be heavy |
| Smell | Fishy, worse after sex | Little or none | Often unpleasant |
| Itching or soreness | Uncommon | Common, often intense | Common, with pain passing urine |
| Vaginal pH | Raised (above 4.5) | Normal (4.5 or below) | Raised |
| Sexually transmitted? | No, but linked to sex | No | Yes, partners need treatment |
| Usual treatment | Metronidazole or clindamycin | Antifungal pessary, cream or tablet | Metronidazole, partner treated too |
Chlamydia and gonorrhoea (gonorrhea) can also cause discharge, and they are often silent, which is why we may suggest a check at the same visit. Burning and frequent urination without discharge point more to a bladder infection; see UTI treatment in Phuket.
How we diagnose and treat BV at Takecare
The doctor asks about your symptoms, periods, contraception, recent sex and any treatments you have tried, and whether you could be pregnant. A quick examination and a vaginal swab allow simple tests: a pH strip to check acidity, and microscopy to look for clue cells, which are vaginal skin cells coated with bacteria. Doctors often use the Amsel criteria, which combine the discharge, pH above 4.5, clue cells and a fishy smell. Results from these simple tests are often available during the visit. If you have had a new partner, we recommend adding STD testing in Phuket to rule out chlamydia, gonorrhoea and trichomoniasis.
First-line treatment is metronidazole, an antibiotic that targets the bacteria behind BV. The usual course is metronidazole tablets twice a day for 7 days, or metronidazole gel inserted into the vagina for 5 nights. Clindamycin cream inserted into the vagina for 7 nights is an alternative. Symptoms usually improve within 2 to 3 days. We dispense treatment from our on-site pharmacy at the same visit.
Recurrence and pregnancy
BV often comes back: up to half of women have another episode within a year. For repeated episodes, the doctor may suggest a longer course followed by suppressive treatment, such as metronidazole gel twice a week for several months, and will review possible triggers. Research also suggests that treating a regular male partner may reduce recurrence, and guidance on this is evolving, so ask us whether it applies to you.
In pregnancy, BV is linked to a higher risk of premature birth and miscarriage. Pregnant women with symptoms should always be treated, and metronidazole is considered safe in pregnancy at standard doses. Tell the doctor if you are pregnant or breastfeeding, so the regimen can be adjusted.
When to see a doctor
See a doctor if you have unusual discharge for the first time, if you are pregnant, if you have had a new partner, if symptoms return after treatment, or if pharmacy thrush treatment has not worked. Come in the same day if discharge comes with lower abdominal pain, fever, pain during sex or bleeding between periods, because these can be signs of pelvic inflammatory disease, an infection of the womb and fallopian tubes. Go to a hospital emergency department or call 1669 if you have severe abdominal pain with fainting, or heavy bleeding in pregnancy.
Prevention and early detection
Avoid douching, vaginal deodorants, perfumed soaps, bubble baths and antiseptic washes, which strip the protective bacteria. Wash the outside of the vulva with plain water or an unperfumed emollient. In Phuket’s heat, change out of wet swimwear promptly and wear breathable cotton underwear. Condoms reduce the risk of BV, and if you share sex toys, wash them between uses. Early detection means seeing a doctor for a proper diagnosis rather than repeatedly self-treating for thrush.

Summary
Bacterial vaginosis is a common imbalance of vaginal bacteria that causes a thin, fishy-smelling discharge. It is not an STI, but it is linked to sex. A quick examination with a pH test and microscopy separates it from thrush and trichomoniasis, and metronidazole or clindamycin clears it in most women. It often recurs, so avoiding triggers and having a plan for repeat episodes matters, and pregnant women should always be treated. Takecare Clinic Phuket diagnoses and treats BV discreetly, any time of day.
“If a thrush cream has not worked within a few days, stop buying more and come in. A two-minute pH test often gives the answer, and the right treatment usually has you feeling normal within days.” Dr. Ponlawat Pitsuwan
Frequently asked questions
Is BV a sexually transmitted infection?
No. BV is an imbalance of the bacteria that normally live in the vagina, and it can happen in women who have never had sex. It is linked to sexual activity, especially a new partner or several partners, but it is not passed on like an STI. A check for STIs is still sensible if you have had a new partner.
How is BV treated?
The usual treatment is metronidazole tablets twice a day for 7 days, or metronidazole gel inserted into the vagina for 5 nights. Clindamycin cream for 7 nights is an alternative. Most women feel better within 2 to 3 days. Finish the full course even if symptoms settle, to reduce the chance of the infection returning.
How do I know if it is BV or thrush?
BV usually causes a thin, grey-white discharge with a fishy smell and little itching. Thrush causes a thick, white discharge with intense itching and soreness but little smell. Because they need completely different treatments, a quick pH test and microscopy at the clinic is the most reliable way to tell them apart.
Why does my BV keep coming back?
Recurrence is common, affecting up to half of women within a year. Douching, perfumed products, a new partner, a copper coil and smoking can all contribute. For repeated episodes, the doctor may suggest a longer course followed by twice-weekly metronidazole gel for several months and will review your triggers with you.
Do I need an appointment for BV treatment in Phuket?
No. Walk in to our Bangtao, Kata or Patong branch at any time of day or night, and you are usually seen within minutes. You can message us on WhatsApp first to confirm the price, or request a doctor visit at your hotel or villa if you prefer a private consultation.
Will my travel insurance cover BV treatment?
Most travel policies cover the consultation, tests and medicine for a new condition that starts during your trip, although some exclude recurring problems. Check your policy wording. We confirm the price on WhatsApp before your visit, offer direct billing with most travel insurers and provide an itemised receipt and medical report for claims.
