Medication details

Description

Ovex Family Pack (4 tablets)

Ovex is a widely used treatment for threadworm, the small worm infection that causes itching around the bottom, particularly at night. Although it is often thought of as a childhood problem, threadworm spreads easily within a household and affects people of all ages. The family pack contains four tablets so everyone in the home can be treated together.

How it works

The active ingredient, mebendazole, stops the worms absorbing the glucose they need to survive, so they die and are passed out naturally. It does not kill the eggs, which is the key to understanding treatment: eggs already in the home can reinfect people days later, which is why hygiene measures matter as much as the tablet and why a second dose after two weeks is often advised.

How to use it

Everyone in the household takes a dose at the same time, as directed on the pack, even those without symptoms, since infection is often silent. On the same day, wash all bedding, towels and nightwear, vacuum thoroughly and damp dust surfaces. For the following two weeks keep nails short, wash hands and scrub under nails first thing in the morning and after the toilet, and shower or bathe each morning to remove eggs laid overnight.

Who it is for

It is for adults and children as stated on the pack. It is not suitable during pregnancy or breastfeeding, or for children under the age stated, so ask a pharmacist about alternatives in those cases.

Safety and when to get advice

Mild abdominal discomfort or wind can occur. See a GP if the infection keeps returning despite treating the whole household and following the hygiene measures, if there is significant abdominal pain, or if worms are seen that do not look like threadworm. Our UK pharmacy team can answer questions about this product before you buy.

Common questions

Does everyone need treating?
Yes. Infection is often silent, so treating one person while others carry it means it simply comes back.

Why do I need to do all the washing?
The tablet kills worms but not eggs. Hygiene measures clear the eggs already in the home.

Do I need a second dose?
A repeat after two weeks is often advised. Ask a pharmacist for your household.

Always read the patient information leaflet supplied with the pack before use.
