Upper Respiratory Tract Infection Treatment in Patong, Phuket: Cold, Sinus and Throat Care 24/7
Same-day clinical assessment for colds, blocked sinuses, and sore throats across Patong, Kalim, and Tri Trang. Clinically reviewed by the Doctor Patong Takecare Clinic medical team.
An upper respiratory tract infection (URI) is a viral infection of the nose, throat, and sinuses. It usually settles in 7 to 10 days with rest, fluids, and simple symptom relief. Antibiotics are rarely needed and do not work against the viruses that cause most colds. We test for COVID-19, influenza, and strep when the story fits, and we step in with antibiotics only when bacterial sinusitis or another complication is clear.

A stuffed nose three days into your holiday, a scratchy throat after a long flight, or a sinus headache that arrives with the rain, this is the single most common reason travellers walk into our Patong clinic. Most of these infections are viral and will settle on their own, but the right symptomatic care, the right swab, and a careful eye for the cases that turn bacterial all make the week far more bearable. Message us, call, or walk in and we will see you the same day.
What causes an upper respiratory tract infection
A URI is a viral inflammation of the upper airway, meaning the nose, the throat (pharynx), the sinuses, the eustachian tubes that link the middle ear to the throat, and the voice box (larynx). Rhinoviruses cause around half of all cases. Non-COVID seasonal coronaviruses, respiratory syncytial virus, parainfluenza, and adenovirus account for most of the rest, with influenza and SARS-CoV-2 overlapping at certain times of year. Cold air-conditioning in transit, recycled cabin air, and the close contact of bars and nightlife in Patong all hand these viruses an easy route from one person to the next. Bacteria such as Streptococcus pneumoniae and Haemophilus influenzae usually only get involved later, when a blocked sinus or middle ear becomes secondarily infected.
Symptomatic care: what actually helps
Treatment is aimed at making you comfortable while your immune system clears the virus. We use paracetamol 1 gram every six hours, up to four grams a day, or ibuprofen 400 mg every eight hours for fever, headache, and body aches. Saline nasal spray or a saline rinse opens the nose without rebound. A topical decongestant such as oxymetazoline 0.05 percent works quickly but is limited to three days because longer use causes rebound congestion. Pseudoephedrine 60 mg every six hours by mouth is useful for blocked sinuses, but we avoid it in uncontrolled high blood pressure, anxiety disorders, and enlarged prostate. Warm fluids, humidified air, throat lozenges, and a teaspoon of honey at bedtime ease cough, with the caution that honey is never given under one year of age. A short course of a first-generation antihistamine such as chlorphenamine 4 mg can dry a runny nose and help sleep.
Complications and when antibiotics are actually indicated
The colour of nasal discharge does not predict bacterial infection. Yellow or green mucus appears in plain viral colds because of activated white blood cells, and antibiotics taken at this stage cause more harm than benefit. We prescribe antibiotics only when the clinical picture genuinely shifts. Acute bacterial sinusitis is the main reason: symptoms persisting beyond ten days without improvement, worsening after an initial improvement (a pattern called double sickening), or severe symptoms from the start with fever of 39 degrees Celsius or higher and purulent nasal discharge for at least three days. First-line treatment is amoxicillin 500 mg three times daily for 5 to 7 days, or doxycycline 200 mg as a loading dose then 100 mg daily for 5 to 7 days if you are allergic to penicillin. We also treat acute otitis media, bacterial pharyngitis confirmed by Centor score and rapid antigen swab, and refer onward if pneumonia is suspected on chest exam.
Cold, flu, COVID-19, or bacterial sinusitis: how we tell them apart
| Feature | Common cold (URI) | Influenza | COVID-19 | Acute bacterial sinusitis |
|---|---|---|---|---|
| Onset | Gradual over 1 to 2 days | Sudden, within hours | 2 to 5 days from exposure | Follows a cold, worsens after day 7 |
| Fever | Low grade or none | High, 38.5 to 40 C | Variable, often present | Often above 39 C with facial pain |
| Body aches | Mild | Severe muscle pain | Common | Localised facial pain over sinuses |
| Smell or taste loss | Mild, from blocked nose | Uncommon | Classic, may be sudden | Possible if sinuses fully blocked |
| Duration | 5 to 10 days, self-limiting | 7 to 10 days, exhausting | Variable, longer if severe | More than 10 days or double sickening |
| Test we use | Clinical, no swab | Rapid influenza antigen | Rapid COVID-19 antigen or PCR | Clinical, imaging only if complicated |
Red flags, seek urgent care today: swelling, redness, or pain around the eye (possible orbital extension of sinusitis), severe headache with neck stiffness or confusion (possible meningitis or brain abscess), fever above 38.5 C lasting more than 5 days, shortness of breath at rest or chest pain, oxygen saturation below 94 percent, coughing up blood (haemoptysis), or facial pain so severe you cannot bend forward. In Phuket we also consider dengue when fever is high with retro-orbital pain and rash but no respiratory symptoms.
See a doctor if symptoms last beyond 10 days without improvement, you get better then worse again (double sickening), you have severe facial pain over the cheeks or forehead, you have an earache that is not settling, your sore throat is severe with swollen tonsils and tender neck glands, you are immunocompromised, you are pregnant, or you have a chronic lung condition such as asthma or COPD.
Prevention and early self-care
Hand hygiene is the single most effective intervention. Wash with soap for 20 seconds, especially after public transport, shared hotel buffet tongs, and after handling tourist money. A well-fitting mask on crowded transfers from the airport, on minivans, and on overnight ferries cuts droplet exposure when other passengers are coughing. The annual influenza vaccine and COVID-19 boosters to current schedule lower both your risk of catching these infections and the chance of complications if you do. Start saline nasal rinses at the first scratch in the throat, sleep with the head of the bed slightly raised, and pause alcohol while symptomatic because it worsens dehydration and disrupts the sleep your immune system needs.
Prevention checklist: regular handwashing, mask in crowded transit, annual influenza vaccine, COVID-19 boosters per current schedule, stop smoking and vaping, treat allergic rhinitis early, and avoid sharing drinks, straws, and lip balm with anyone visibly unwell.
Summary
An upper respiratory tract infection is uncomfortable but rarely dangerous. Our role at the clinic is to confirm it is what you think it is, swab for COVID-19, influenza, or strep when the story justifies it, give you a clear symptomatic plan, and watch carefully for the small minority that develop bacterial sinusitis, ear infection, or pneumonia. Antibiotics earn their place only when there is a real bacterial signal.
“A good cold consultation is not a prescription for antibiotics. It is a careful exam, the right swab, a plan to sleep through the night, and a clear list of warning signs that should bring you back.” Doctor Patong Takecare Clinic medical team
Frequently asked questions
Do I need antibiotics for my cold or sinus infection?
Almost never. More than 90 percent of upper respiratory infections are viral, and antibiotics do not work against viruses. Taking them anyway gives you side effects, encourages resistant bacteria, and does not shorten your illness. We prescribe antibiotics, usually amoxicillin or doxycycline if you are penicillin-allergic, only when there is a clear bacterial signal such as sinusitis worsening after day 10, double sickening, high fever with purulent discharge for three days or more, or a confirmed bacterial throat infection.
My mucus is yellow or green, isn’t that a sign I need antibiotics?
No. Coloured mucus reflects the white blood cells your body is sending to fight the infection. It appears in viral colds and clears as the cold resolves. Both the CDC and NICE state that mucus colour does not reliably distinguish viral from bacterial infection and should not by itself trigger an antibiotic.
How long does a cold or URI usually last?
Most symptoms peak on days 2 to 4 and settle by days 7 to 10. A dry cough can linger for two to three weeks as the airway lining recovers. If your symptoms have not started to improve at all by day 10, if they worsen after improving, or if a new fever develops, we recommend a clinic review for possible bacterial sinusitis or another complication.
Should I get tested for COVID-19 or flu?
Yes, when the clinical picture justifies it. We run a rapid COVID-19 antigen test if you have a recent contact, sudden loss of smell or taste, or significant fever. We add a rapid influenza test if your illness began suddenly with high fever and severe body aches. Knowing the result changes treatment, isolation advice, and travel decisions, especially if you are due to fly.
Could this actually be dengue rather than a cold?
Phuket sees year-round dengue, with peaks in the rainy season. Dengue typically presents with high fever, severe headache behind the eyes, body aches, and a rash, but importantly without a runny nose or sore throat. If your fever is high and you have very few respiratory symptoms, especially with low platelet warning signs such as easy bruising or gum bleeding, we run a dengue NS1 antigen and a full blood count rather than treating you as a simple cold.
When should I worry about sinusitis spreading?
Rare but serious. Bacterial sinusitis can spread to the tissues around the eye (orbital cellulitis) or, very rarely, into the brain. Warning signs are swelling, redness, or pain around the eye, double vision, severe one-sided headache with neck stiffness, high fever with confusion, or any drowsiness that is out of character. These need emergency hospital assessment, not a clinic visit.
