Herpes Treatment in Phuket: Confidential Care and Same-Visit Antivirals
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Takecare Clinic Phuket. Last reviewed: September 2026.
“A first herpes outbreak on holiday is miserable. People arrive at our Kata branch in pain, sometimes unable to pass urine comfortably, and frightened about what the diagnosis means for the future. The first thing I tell them is that this is one of the most common infections in the world, and the first episode is almost always the worst. Heat, friction from wet swimwear and long days in the sun can make sores more uncomfortable, but they heal.” Dr. Ponlawat Pitsuwan
What genital herpes is
Herpes simplex virus spreads through close skin-to-skin contact, and in genital herpes that almost always means sexual contact, including vaginal, anal and oral sex. There are two types. HSV-2 mainly causes genital herpes. HSV-1 is the usual cause of cold sores on the lips, but it now causes a large share of new genital infections through oral sex. WHO estimates that most adults worldwide carry at least one type, and most do not know it.
After the first infection, the virus stays dormant (asleep) in the nerve roots near the spine and can reactivate later, causing a recurrence in the same area. Common reactivation triggers include illness, stress and strong sun exposure, which is particularly relevant on a beach holiday. Recurrences are usually milder, shorter and less frequent over time, and genital HSV-1 tends to recur less often than HSV-2. The virus can also be passed on when there are no symptoms, which is called asymptomatic shedding.
Symptoms and look-alikes
A first episode usually appears 2 to 12 days after contact. It starts with tingling, itching or burning, followed by small blisters that break into shallow, painful ulcers on the genitals, buttocks, anus or inner thighs. Many people also have fever, aches, swollen glands in the groin and pain when passing urine. The sores crust and heal over about 2 to 4 weeks without treatment.
Recurrences often begin with a prodrome, a warning tingle or ache in the same spot a few hours to a day before blisters appear. Other causes of genital sores include syphilis (usually a single, painless ulcer), friction injuries, fungal infections and ingrown hairs, which is why testing matters, especially after a new partner.
| Situation | Usual antiviral approach | Timing |
|---|---|---|
| First episode | Aciclovir or valaciclovir tablets for 5 to 10 days | Start within 5 days of onset, or while new sores are still forming |
| Occasional recurrence | Short episodic course, often 1 to 5 days | Best at the first tingle, within 24 hours |
| Frequent or distressing recurrences (often 6 or more a year) | Daily suppressive therapy | Continuous, reviewed after about a year |
| Late pregnancy with a history of herpes | Suppressive aciclovir often advised | From 36 weeks, under obstetric care |
How we diagnose and treat herpes at Takecare
The doctor examines you privately and, where it helps, takes a swab from a fresh sore for a PCR test, which detects the virus’s genetic material and tells HSV-1 from HSV-2. Knowing the type helps predict how often it may recur. Blood tests for herpes antibodies are not routinely recommended, because they cannot tell where the infection is or when it was caught. We usually offer wider STD testing in Phuket, including syphilis and HIV, because a new genital ulcer should never be assumed to be herpes alone.
Antivirals do not remove the virus, but they stop it multiplying, which shortens the outbreak, eases pain and reduces shedding. For a first episode, guidelines recommend aciclovir or valaciclovir for 5 to 10 days, and we start treatment from our on-site pharmacy at the same visit. Pain relief, salt-water bathing, loose cotton underwear and petroleum jelly or an anaesthetic gel on the sores all help. If passing urine is very painful, doing so in a cool bath or shower can help.
For people with frequent outbreaks, daily suppressive therapy, usually valaciclovir or aciclovir, can prevent most recurrences and roughly halves the chance of passing the virus to a partner. Episodic treatment, a short course kept at home and started at the first tingle, suits people with fewer outbreaks.
Herpes and pregnancy
If you are pregnant, tell the doctor. A recurrence in pregnancy carries a low risk to the baby, but a first infection caught in the last 6 weeks of pregnancy carries a higher risk of neonatal herpes, a serious infection in a newborn. Anyone with genital sores in late pregnancy needs prompt review by an obstetrician, who may recommend antivirals and discuss delivery by caesarean section.
When to see a doctor
See a doctor for any new genital blisters or ulcers, especially after a new partner, and ideally within the first few days while antivirals work best. Come in the same day if you cannot pass urine, have a severe headache, stiff neck or dislike of bright light, have sores spreading widely, or have a weakened immune system. Being unable to pass urine at all is an emergency. Go to a hospital emergency department or call 1669 for confusion, a seizure or a severe headache with fever, which can rarely indicate herpes infection of the brain or its lining.
Prevention and early detection
Avoid sex, including oral sex, from the first tingle until sores have fully healed. Condoms reduce but do not remove the risk, because the virus can spread from skin they do not cover. Someone with a cold sore should not give oral sex, as HSV-1 passes easily to the genitals. Daily suppressive therapy lowers transmission in ongoing relationships, and telling partners lets them make informed choices. Keeping lips protected with SPF helps prevent the sun-triggered outbreaks that often start on holiday.
Visiting Takecare Clinic in Phuket
All three branches are open 24/7, and walk-ins are welcome. Come to Takecare Clinic Bangtao (Cherngtalay), Takecare Clinic Kata-Karon or Takecare Clinic Patong. Most visits take under 30 minutes, and antivirals are dispensed on site.
You can message us on WhatsApp or call 081-718-9080. We confirm the price on WhatsApp before your visit. If walking is painful, a doctor can visit you at your hotel. We give itemised receipts and medical reports for insurance, with direct billing with most travel insurers where the policy covers it.
Related services and treatments
Lip blisters from HSV-1 are treated with the same family of antivirals, as explained on our cold sore treatment page. A painful band of blisters on one side of the body is usually shingles, caused by a related virus, and needs shingles treatment within 72 hours. If your screen shows other infections, we offer chlamydia treatment and an HIV test in Phuket. For discharge with a fishy smell, see BV treatment, and if you are at ongoing HIV risk, our PrEP clinic in Phuket can help. A walk-in doctor in Phuket is available at every branch for anything else.
Summary
Genital herpes is common, caused by HSV-1 or HSV-2, and manageable. The first episode is usually the worst and responds well to 5 to 10 days of aciclovir or valaciclovir. Recurrences are milder and can be treated at the first tingle or prevented with daily suppressive therapy, which also lowers the chance of passing it on. Pregnant women with sores need prompt specialist review. At Takecare Clinic Phuket you can be examined and treated in private at any hour.
“Herpes is a skin infection that comes and goes, not a judgement on you. Start antivirals early, rest, keep the area clean and dry, and give yourself time to heal before sex.” Dr. Ponlawat Pitsuwan
Frequently asked questions
Can genital herpes be cured?
No treatment removes the virus from the body, but antivirals control it well. They shorten outbreaks, ease pain and, taken daily, prevent most recurrences and reduce transmission. For most people outbreaks become milder and less frequent over the years, and many have very few after the first year.
How quickly do herpes antivirals work?
Started early, aciclovir or valaciclovir shorten a first episode by several days and reduce pain and new blisters within 2 to 3 days. For recurrences, they work best when started at the first tingle, ideally within 24 hours. Once sores have fully crusted, antivirals add little, and healing simply takes a few more days.
Can I pass herpes on when I have no symptoms?
Yes. The virus can be shed from the skin without any sores, although the risk is lower than during an outbreak. Avoiding sex during outbreaks, using condoms and taking daily suppressive therapy together greatly reduce the risk of passing herpes to a partner.
Is it herpes or something else?
Painful clusters of small blisters that turn into shallow ulcers are typical of herpes, but syphilis, friction injuries, fungal infections and ingrown hairs can look similar. A swab from a fresh sore confirms the diagnosis, and we usually test for syphilis and HIV at the same time, especially after a new partner.
Do I need an appointment for herpes 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 message us on WhatsApp first to confirm the price, or ask for a doctor to visit your hotel or villa if you are too uncomfortable to travel.
Will my insurance cover herpes treatment?
Cover depends on your policy. Many travel policies pay for treatment of a new illness that starts during your trip, while some exclude sexually transmitted infections or conditions you had before travelling. We confirm the price on WhatsApp before your visit and provide an itemised receipt and medical report for your claim.
