## The short answer

Mebendazole is used for worm infections, including threadworms. A household hygiene plan is important because treatment does not clear eggs from the environment. Check age restrictions, pregnancy and who else needs advice.

## Understanding your options

Threadworms can cause intense itching around the bottom, especially at night. They are common in children and can spread within households.

Pharmacy treatment and careful hygiene are used together. Household advice matters because medicines do not remove eggs from the environment.

## Who may be suitable?

Ask a pharmacist about young children, pregnancy and breastfeeding before treatment.

## Side effects and precautions

Follow age restrictions and the product directions. Handwashing, short nails and cleaning bedding and clothing help reduce spread.

## When to get help

Get advice if the diagnosis is unclear, there is significant pain or repeated treatment is not helping.

For a life-threatening emergency, call 999. For urgent advice, contact the appropriate local NHS service.

## Progress and follow-up

Continue hygiene measures for the recommended period and seek advice if symptoms persist.

## Questions to ask

Who should be treated and what hygiene steps prevent reinfection?

- Who in the household should be treated?

- What is appropriate for the youngest family member?

- How long do we need the hygiene routine?
