The most effective medical treatment for threadworms is a medication called Mebendazole (available as Ovex or generic tablets). It works by preventing the worms from absorbing sugar, which causes them to die within a few days. At Chemist 2 Home, we provide single-dose tablets and oral suspensions that can be ordered online following a quick consultation with our UK clinicians.

Yes. Threadworms are highly contagious, and eggs are easily spread through shared surfaces, towels, and bedding. Even if only one person shows symptoms such as an itchy bottom at night, it is essential to treat every member of the household simultaneously to prevent the infection from being passed back and forth.

A single dose of Mebendazole is usually over 90% effective at killing the adult worms in the gut. However, the medication does not kill the eggs. This is why strict hygiene measures are necessary for two weeks after treatment, and a second dose is often recommended 14 days later to kill any worms that may have hatched from eggs swallowed before the first dose.

Yes. We offer threadworm treatments suitable for children over the age of two. For younger children who may struggle with tablets, Mebendazole oral suspension (liquid) is a popular and effective alternative. Simply complete our online assessment to ensure the treatment is appropriate for your child’s age and weight.

To stop re-infection, you must eliminate any eggs in the home. On the day of treatment, you should:

• Wash all bed linen, towels, and nightwear on a hot cycle.
• Vacuum the house thoroughly, especially bedrooms.
• Scrub fingernails and ensure everyone washes their hands regularly, particularly before eating.
• Shower every morning to wash away eggs laid around the anus during the night.
