Threadworm is one of the everyday conditions our pharmacists treat through our free NHS minor illness service — advice and treatment without a GP appointment.

Speak to our pharmacist in the private consultation room. Where appropriate we can supply treatment free of charge under the local NHS minor ailments scheme, or recommend the best over-the-counter option.
Free NHS treatment is available if you are registered with a participating local GP and do not pay for prescriptions; everyone else can still get expert advice and low-cost treatment. Use our one-minute eligibility checker and our pharmacist will be in touch to arrange your consultation — or just walk in.
What it is, what to look out for, and what actually helps — from the pharmacists who treat it every day.
Threadworms are tiny white worms — like short pieces of cotton thread — that live in the gut and lay eggs around the bottom at night, causing intense itching. They're extremely common in children and spread through swallowed eggs picked up from hands, surfaces and bedding.
The itch-scratch-swallow cycle is how they keep going: scratching collects eggs under fingernails, and the eggs find their way back to the mouth. Treatment is a simple single-dose medicine for the whole household, paired with two weeks of strict hygiene to break the cycle — our pharmacist can supply everything and talk you through it.
