Air conditioning, long flights and late nights mean I see plenty of sore throats in visitors. Most are viral and settle within a week, and I spend a lot of time explaining why antibiotics would not help, while watching for the small number of cases that do need them.
A sore throat is one of the most common reasons holidaymakers walk into our clinics, and the cause is often part of the holiday itself. Hours of shouting over music in Patong bars, sleeping under a cold air-conditioning vent, cigarette and shisha smoke, and a virus picked up on the flight all leave the throat raw. Shared drinking buckets and straws pass infections quickly around a group of friends. Most of these throats need soothing rather than antibiotics, and the skill lies in spotting the few that do not.
Why your throat hurts
The medical term is pharyngitis, inflammation of the pharynx, the passage behind the mouth and nose. In adults, viruses cause the large majority: the same ones behind colds, flu and COVID-19. Group A streptococcus, the bacterium behind strep throat, causes only around 5-15% of adult sore throats. When the inflammation centres on the tonsils, the diagnosis becomes tonsillitis.
Not every sore throat is an infection. Chilled air conditioning dries the throat overnight, and voice strain, smoking, vaping, acid reflux after late meals and alcohol, and post-nasal drip from allergy all irritate the lining. Less often, glandular fever or gonorrhoea of the throat after oral sex is responsible, and a sore throat with fever and rash a few weeks after unprotected sex can be an early sign of HIV, so mention any recent risk to the doctor.
Viral throat or strep throat? The clues we look for
| Feature | More likely viral | More likely strep | Non-infectious look-alikes |
|---|---|---|---|
| Cough, runny nose | Usually present | Usually absent | Allergy: sneezing, itchy eyes |
| Fever | Mild or none | Often above 38°C | None |
| Tonsils | Red, mildly swollen | Swollen, with white or yellow pus | Normal |
| Neck glands | Mildly tender | Tender and swollen at the front | Normal |
| Pattern | Gradual, with a cold | Sudden, within a day | Air conditioning or reflux: worst on waking |
Doctors combine these features into a validated score, FeverPAIN or Centor, which our tonsillitis treatment page explains point by point. A low score means antibiotics would not help; a high score raises the chance of strep, and a throat swab can add information when the picture is borderline.
When antibiotics make sense, and when they do not
For a viral throat, antibiotics do nothing for the pain or the length of illness and bring diarrhoea, thrush and rashes. Even for strep in a healthy adult, the benefit is modest: symptoms shorten by less than a day on average, with a small reduction in complications such as quinsy, an abscess beside the tonsil. Antibiotics make sense when the score is high, when you are very unwell or immunosuppressed, or when you are not improving after three to five days. Sometimes the doctor gives a back-up prescription to start only if that happens. The usual first choice is penicillin V, with clarithromycin for people allergic to penicillin.
In Thailand, pharmacies can sell some antibiotics without a prescription. That is convenient, but a random course of amoxicillin for a viral throat adds side effects and resistance without helping, and in glandular fever amoxicillin often triggers a widespread itchy rash. A short examination is the better route.
Soothing a sore throat while it heals
Most viral throats improve within a week, so the aim is comfort. Paracetamol or ibuprofen taken regularly for a couple of days controls pain better than occasional doses, but if you also have a high fever and body aches in Phuket, use paracetamol only until dengue has been ruled out. Gargle with half a teaspoon of salt in a glass of warm water, sip honey in warm water or tea (not for babies under one), and use anaesthetic lozenges or sprays for short spells of numbness. Cold drinks or a fruit shake from a beach stall often feel better than hot ones. Drink more than usual after a day in the sun, rest your voice, and skip smoky bars for a few nights.
When to see a doctor
A sore throat alone rarely needs urgent care, but some combinations do. Drooling or being unable to swallow saliva, a muffled “hot potato” voice, trouble opening the mouth or severe one-sided pain can mean an abscess threatening the airway. People taking medicines that can suppress white blood cells, such as carbimazole, methotrexate or chemotherapy, need a same-day blood count for any sore throat with fever.
Prevention and early detection
Wash your hands before eating, and do not share glasses, straws, vapes or drinking buckets, especially with anyone already sniffing or coughing. Keep up fluids in the heat, avoid sleeping in a cold air stream, and give your voice a break after a big night. Stopping smoking removes one of the commonest causes of a lingering raw throat, and condoms or dental dams for oral sex reduce throat infections from gonorrhoea and chlamydia. For early detection, a hoarse voice lasting three weeks or more, particularly in a smoker, should be checked by an ear, nose and throat specialist rather than blamed on the holiday.
Seeing us for a sore throat
Walk in at any hour at our Bangtao (Cherngtalay) clinic, the Kata-Karon clinic or our clinic in Patong. A throat check is quick, and most walk-in visits take under 30 minutes, including medicine from the on-site pharmacy. If swallowing hurts too much to talk, message us on WhatsApp or phone +66 81 718 9080, and we can arrange a doctor to visit your hotel day or night. We confirm the price on WhatsApp before your visit, bill most travel insurers directly, and provide a receipt, medical report and itemised invoice for claims.
Related services and treatments
A sore throat is often one symptom of something bigger. With sudden fever and aches it may be influenza, covered under flu treatment, and a positive coronavirus swab leads to COVID-19 treatment. When a cough settles on the chest afterwards, see bronchitis treatment; if pain spreads to one ear, read about ear infection treatment; and a scratchy throat with sneezing points towards allergy treatment. Throat viruses often set off wheezing, which our asthma treatment page covers, and a fever without an obvious source is explained under fever treatment in Phuket. For quick care without booking, see our walk-in doctor in Phuket service or all the conditions we treat.
Summary
Most sore throats are viral, last about a week and respond best to fluids, regular painkillers, gargles and voice rest. Antibiotics are worthwhile only when the pattern points to strep. Get checked if the pain is one-sided, you cannot swallow, the fever is high, or the throat has not improved in a week.
“Warm drinks, rest and regular paracetamol help most sore throats. Come back if you cannot swallow fluids, struggle to open your mouth or the pain is getting worse.”

Frequently asked questions
How can I tell whether my sore throat needs antibiotics?
A cough, runny nose and hoarse voice point towards a virus, which antibiotics cannot treat. Fever, pus on the tonsils, tender swollen glands at the front of the neck and no cough point towards strep. Doctors combine these features into a score, so if you have several bacterial features, it is worth being examined.
Can I just buy antibiotics from a pharmacy in Phuket?
Some antibiotics are sold over the counter in Thailand, but that does not make them the right choice. Most sore throats are viral, so an antibiotic adds side effects and resistance without helping. The wrong drug or too short a course may not clear strep, and amoxicillin can cause a heavy rash in glandular fever.
What will a sore throat visit cost, and will insurance pay?
The cost depends on whether you need tests or medicine, so we confirm the price on WhatsApp before your visit. Most travel insurance covers illness abroad, subject to your excess. We bill most travel insurers directly, and otherwise provide a receipt, medical report and itemised invoice for your claim.
Do I need to book, and how long will it take?
No booking is needed. All three clinics are open 24 hours a day and walk-in patients are usually seen within minutes. The examination, any test and collecting medicine from our pharmacy usually take less than 30 minutes in total, and a WhatsApp message first lets us know you are coming.
Can a doctor come to my hotel for a sore throat?
Yes, a doctor can visit your hotel, villa or condo anywhere in Phuket, 24/7. This helps when swallowing is so painful you are struggling to drink, when the fever is high, or when you would rather not bring the whole family to the clinic. The doctor examines your throat and neck and arranges treatment.
How long should a sore throat last before I start to worry?
A viral sore throat usually peaks in two to three days and settles within about a week. Get checked if it has not improved after a week, keeps coming back, or is getting worse instead of better. A hoarse voice lasting three weeks or more needs assessment even if the pain has gone.
