Pink Eye Treatment in Bangkok – Same Day Conjunctivitis Care

Pink eye is a common reason travelers and expats walk into our clinic. The medical term is conjunctivitis, an inflammation of the thin clear membrane that lines the eyelid and covers the white of the eye. The eye looks red or pink, feels gritty or itchy, and often produces watery or sticky discharge. Most cases are mild, but a doctor needs to distinguish viral, bacterial, and allergic conjunctivitis because the treatment and contagious period are different for each. Take Care Clinic provides same day diagnosis and prescription drops on Sukhumvit Soi 13, with hotel and home visits available across central Bangkok.

What pink eye actually is

Conjunctivitis means the conjunctiva is inflamed. The three main causes seen in Bangkok adults and children are viral infection, bacterial infection, and allergy. Newborn conjunctivitis and chemical conjunctivitis from chlorinated pools or smog are less common but real. Viral conjunctivitis usually follows a cold or sore throat and is the most contagious form. Bacterial conjunctivitis produces thicker yellow or green discharge and crusting that glues the lashes together overnight. Allergic conjunctivitis affects both eyes, itches intensely, and flares with PM2.5 spikes, hotel air conditioning, or pollen seasons.

Symptoms our doctors look for

Patients describe a red eye, a feeling of sand or grit under the lid, watery or sticky discharge, light sensitivity, swollen lids, and crusting in the morning. Vision is usually normal. Itching that dominates the picture points strongly to allergy. A single red eye with severe pain, blurred vision, or a fixed pupil is not simple pink eye and needs immediate ophthalmology review to rule out keratitis, iritis, or acute glaucoma. We screen for these red flags at every visit.

How we diagnose pink eye at the clinic

Diagnosis is clinical in most cases. The doctor takes a history of recent colds, contact lens use, swimming, hotel pool exposure, allergy history, and any recent travel. We examine both eyes with a bright light and a magnifier, evert the upper lid to look for follicles or papillae, check the cornea for staining, and assess visual acuity. We swab discharge for culture only when the case is severe, recurrent, or not responding to first line treatment. If we suspect herpes simplex keratitis or any corneal involvement we refer urgently to an ophthalmologist for slit lamp evaluation the same day.

Treatment by cause

Viral conjunctivitis is self limiting and usually clears within seven to fourteen days. We provide preservative free artificial tears, cool compresses, and clear hygiene instructions to limit spread. Antibiotic drops do not help viral disease and are not prescribed. Bacterial conjunctivitis responds quickly to topical antibiotic drops or ointment, most commonly chloramphenicol, fusidic acid, or a fluoroquinolone such as moxifloxacin for contact lens wearers where Pseudomonas coverage matters. A typical course runs five to seven days. Allergic conjunctivitis is treated with antihistamine and mast cell stabiliser drops such as olopatadine, plus oral antihistamines when systemic symptoms are present. We provide allergen avoidance advice for travelers staying in dusty hotels or during high PM2.5 days. The CDC, AAO, and NHS all align on this stepwise approach.

Contact lens wearers, pool swimmers, and contagious cases

Contact lens users with red eye need urgent review because a corneal ulcer from Pseudomonas can destroy vision within days. We tell every lens wearer to stop wearing lenses, switch to glasses, bring the lenses and case to the clinic, and not restart until the eye is fully clear and the doctor agrees. Swimmers and divers in Thailand sometimes develop bacterial or chemical conjunctivitis after exposure to poorly chlorinated pools; we treat the infection and advise a break from the water until symptoms settle. Viral conjunctivitis is highly contagious; people should not share towels, pillows, or eye makeup, and should wash hands often. Children should stay home from school while discharge is active.

When to see a doctor urgently

Most pink eye is mild but the following need same day medical review. Severe pain in or around the eye. Vision changes such as blurring, double vision, or halos around lights. A foreign body sensation that does not resolve with blinking and tearing. Photophobia that is disabling. A red eye in a contact lens wearer. Discharge so thick the lids stick shut despite cleaning. Any history of recent eye surgery, trauma, or herpes infection. Red eye with fever, lethargy, or rash in a child under one year. Our doctors triage these presentations same day at Sukhumvit Soi 13 or by hotel visit, and refer for ophthalmology when corneal pathology is suspected.

Pink eye in children

Kids pick up viral and bacterial conjunctivitis from school and daycare. We provide weight based antibiotic drops when bacterial infection is likely, simple hygiene advice for parents, and a doctor’s note for school when needed. Newborns with red eye in the first month of life need a different work up because gonorrhoea, chlamydia, and herpes are possible causes; we refer these cases to a paediatric ophthalmologist.

Prevention tips for travelers and expats

Wash hands often, do not rub the eyes, do not share towels or eye makeup, swim in well chlorinated pools, take regular contact lens breaks, replace lenses on schedule, and never sleep in daily disposables. During the burning season and Bangkok haze episodes, use preservative free artificial tears, wear wraparound sunglasses outdoors, and run an air purifier indoors. People prone to allergic conjunctivitis can pre treat with antihistamine drops before high pollen days.

FAQ

How long does pink eye last? Viral usually clears in seven to fourteen days. Bacterial improves within twenty four to forty eight hours of antibiotic drops. Allergic settles once the trigger is removed and treatment is given.

Can a doctor visit my hotel room? Yes. We provide doctor hotel visits across central Bangkok. The doctor arrives within sixty to ninety minutes with the necessary drops and an itemised receipt for insurance. See our doctor hotel visit page for details.

Will my travel insurance cover this? Most travel and expat health plans cover acute eye infections. We provide a doctor’s letter, itemised invoice, and prescription details in English. Bring your insurance card and passport.

Is pink eye contagious? Viral and bacterial cases are contagious until discharge stops; allergic conjunctivitis is not. Wash hands often, use a separate towel, and stay home until the discharge has cleared.

Do I need antibiotic drops? Only if the doctor diagnoses bacterial conjunctivitis or you are a contact lens wearer. Viral and allergic cases are managed without antibiotics.

I am a contact lens wearer with a red eye, what should I do? Stop wearing the lenses immediately, switch to glasses, and see a doctor the same day. Contact lens related red eye can be a sight threatening emergency.
