Pinworms (threadworms) while visiting Sweden
Medically reviewed by Dr Toha Soodhun, specialist in family medicine · 15 November 2026
Pinworms are a common, harmless intestinal parasite, especially in children. The main sign is itching around the bottom, mostly in the evening and at night. The worms are white, thread-thin and up to about a centimetre long. Two over-the-counter medicines are sold at Swedish pharmacies; everyone in the household is treated at the same time, and the dose is repeated after two weeks.
Treatment
- Only treat once worms have actually been seen — itching can have other causes.
- Treat everyone who lives together at the same time.
- Repeat the treatment after two weeks, because the medicines do not kill the eggs.
- If you are pregnant, or the child weighs under 10 kg or is under two years, ask a doctor first.
Hygiene during treatment
- Wash hands after the toilet, before meals and when you wake up. Keep nails short.
- Wash the bottom every day; change underwear, pyjamas and often bed linen.
- Wash textiles the same day they are changed, without shaking them first.
- Vacuum or dust the bedroom and bathroom, ideally daily.
See a doctor in person if…
- Symptoms remain after two courses of treatment two weeks apart

Questions
Do I need to see a doctor?
Usually not — the treatment is sold without prescription. A video doctor can help if you are unsure, pregnant, or treating a young child.
Can my child go to school?
In Sweden children with pinworms do not usually need to stay at home, but extra hand hygiene is important.
