About Us
Threadworms are a common ailment. These small parasitic worms cause irritation and discomfort in the anal area, leading to itching and difficulty sleeping. Thankfully, the National Health Service in Wales offers a thorough treatment service to eliminate threadworms and promote better health for children.
Simple daily routines to reduce spread.
Practical Prevention Tips
A routine focused on hygiene dramatically reduces transmission risk. Encourage handwashing with soap and warm water especially after using the toilet and before eating. Keep fingernails short and avoid nail biting or thumb sucking. Wash bedding, night clothes and towels in hot water each week during an outbreak. Vacuum and wipe bedroom surfaces regularly. Where possible, bathe children each morning to remove eggs laid overnight. These combined measures minimise environmental contamination and support the effectiveness of medical treatment, reducing the chance of reinfection within households and schools.

Frequently Asked Questions
Common questions about causes, treatment and when to get help.
How do you get threadworms?
Eggs are picked up from contaminated hands, surfaces or bedding and swallowed, leading to infection when they hatch in the gut.
Can adults get threadworms?
Yes. Adults who live with or care for children are commonly infected and should be treated simultaneously.
What treatments are available?
Anthelmintic tablets or liquid are effective; some products are available over the counter. A second dose after two weeks is recommended.
When should I see a GP?
See a GP if symptoms persist after treatment, if there are severe symptoms, or if you are pregnant or breastfeeding before taking medication.
How can reinfection be prevented?
Wash hands and under fingernails, keep bedrooms and bathrooms clean, wash bedding and pyjamas in hot water, and avoid nail biting and thumb sucking.
Persistent or worrying symptoms.
When to Seek Further Help
Contact your GP or pharmacy if symptoms persist after two treatments, if you notice heavy infection signs like weight loss or severe abdominal pain, or if medication is unsuitable due to pregnancy or other health conditions. Our pharmacy team can advise on suitable over-the-counter options and when to refer for additional care.
