Scabies Treatment in Bangkok – Same Day Permethrin and Ivermectin

Scabies is one of the most common skin infections we treat in travelers, expats, and families in Bangkok. It is caused by a microscopic mite called Sarcoptes scabiei var hominis that burrows into the upper layer of the skin, lays eggs, and triggers an intensely itchy rash that worsens at night. Backpackers picking it up from shared hostel bedding, families with school children, and patients returning from rural travel are typical cases. Take Care Clinic on Sukhumvit Soi 13 diagnoses scabies the same day and prescribes topical permethrin or oral ivermectin, with hotel and home visits available across central Bangkok.

What scabies is and how people catch it

Scabies is a skin infestation, not a sign of poor hygiene. The female mite tunnels into the skin and lays two to three eggs a day. The body reacts to the mite, the eggs, and their droppings with an allergic itch that often only develops three to six weeks after first contact. People who have had scabies before will itch within one to three days because the immune system is already sensitised. Transmission is through prolonged skin to skin contact, typically fifteen minutes or more, which is why household members, sexual partners, and people sharing beds are the most common sources. Clothing, towels, and bed linen can transmit the mite for up to three days after they were last used.

Symptoms our doctors look for

Patients describe relentless itching that is worse at night, a rash of small red bumps, fine burrow lines on the wrists, finger webs, elbows, armpits, waistband, buttocks, genitals, and ankles. In children the face, scalp, palms, and soles can also be involved. Scratching often leads to crusts, scabs, and secondary bacterial infection of the skin. Crusted (Norwegian) scabies is a severe form seen in immunocompromised patients and produces thick scaly plaques teeming with mites; it is much more contagious and needs aggressive treatment.

How we diagnose scabies at the clinic

Diagnosis is clinical in most cases. The doctor takes a history of itch pattern, household and travel contacts, hostel or hotel stays, and any failed self treatment. We examine the classic sites looking for burrows, papules, and excoriations, and use a dermatoscope to identify the mite or its track. We may scrape a burrow and look for the mite, eggs, or faecal pellets under the microscope when the diagnosis is uncertain. We also check the skin for signs of secondary bacterial infection that need antibiotic cover.

Treatment that works

First line treatment is permethrin 5 percent cream applied from the neck down (and to the scalp in young children, the elderly, and crusted scabies). The patient leaves the cream on for eight to fourteen hours, usually overnight, then washes it off. A second application seven days later is essential to kill mites that hatched from eggs the first dose did not penetrate. Oral ivermectin is used as an alternative or in addition for crusted scabies, outbreaks, and patients who cannot tolerate topical therapy. The standard dose is 200 micrograms per kilogram body weight, repeated after seven to fourteen days. Children under fifteen kilograms and pregnant women need a different regimen, and we tailor the choice individually. CDC, WHO, and Cochrane reviews all support this approach.

Itch after treatment is normal

The itch can last two to four weeks after successful treatment because the body is still reacting to dead mites and eggs in the skin. This does not mean treatment has failed. We prescribe antihistamines, a short course of topical steroid for severely inflamed areas, and emollients. If the rash is still spreading after four weeks, or new burrows appear, treatment is repeated and contacts are reviewed.

Household and travel decontamination

All clothing, bedding, and towels used in the three days before treatment must be machine washed at sixty degrees or higher and tumble dried, or sealed in a plastic bag for at least seventy two hours. Mattresses and upholstery should be vacuumed thoroughly. Everyone in the same household, sexual partners, and anyone with prolonged close contact should be treated at the same time even if they have no symptoms; this is the single most important step in preventing reinfestation. Travelers staying in hostels or shared rooms should treat their luggage and laundry the same way before flying home.

When to see a doctor

See a doctor the same day if the rash is spreading rapidly, weeping pus, accompanied by fever, or has not improved after two correct permethrin applications. Patients with HIV, on chemotherapy, or on long term steroids who develop a crusted, thick, scaly rash need urgent review for crusted scabies. Any infant under two months of age with a suspected scabies rash should be assessed by a doctor before any topical therapy. Pregnant and breastfeeding women should not self medicate; we use permethrin in pregnancy because the safety record is strong but the regimen needs medical supervision.

Scabies in children and at school

Children can return to school twenty four hours after the first permethrin application is washed off, provided their clothing and bedding have been laundered. We provide a doctor’s letter for international schools in Bangkok. Family members and close playmates should be treated together to prevent ping pong reinfestation between households.

Cost and how to book at Take Care Clinic

An in clinic consultation with a doctor starts at THB 1,500. Permethrin 5 percent cream and ivermectin tablets are stocked on site; a full treatment course for one adult typically costs THB 800 to 1,500. Hotel and home visits within central Bangkok start at THB 3,500 and include the doctor visit and the medication for the night. We provide itemised receipts in English for travel insurance reimbursement. Most insurers cover acute skin infections and prescription topical therapy.

Prevention tips for travelers and expats

Avoid using shared bedding, towels, and clothing in hostels and budget guesthouses. Inspect mattresses and linens before settling in. Wash backpacking gear at sixty degrees on return. If you sleep in a hotel that you suspect of poor hygiene and develop nocturnal itch in the next three to six weeks, book a doctor visit early because treating one person is far cheaper than treating an entire household later.

FAQ

Can a doctor visit my hotel room for scabies? Yes. We provide doctor hotel visits across central Bangkok. The doctor arrives within sixty to ninety minutes with permethrin cream or ivermectin tablets and an itemised receipt for insurance. See our doctor hotel visit page.

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

How long until the itch stops? Itching can persist for two to four weeks after successful treatment because the immune system continues to react to dead mites in the skin. Antihistamines and emollients help during this time.

Do I need to treat my partner if they have no symptoms? Yes. Asymptomatic contacts can be in the silent three to six week pre rash window. Treating everyone at once prevents reinfestation.

Is scabies a sexually transmitted infection? It is not an STI in the classic sense, but prolonged skin contact during sex is a very efficient way to transmit it. We also screen for STIs when the history suggests it.

Can I use over the counter creams instead? Over the counter creams and home remedies do not kill the mite. Prescription strength permethrin or oral ivermectin is required.
