Ovex Suspension Banana Flavour 30ml

Ovex Suspension is a medicine, which is used to treat threadworm (sometimes known as pinworm) infections of the gut. The medicine contains mebendazole, which is one of a group of medicines called ‘anthelmintics’. 

This medicine is suitable for most adults and children aged over 2 years. If your are in any doubt, talk to your doctor or pharmacist.

A single dose of this medicine will kill threadworms. However, it may not destroy their eggs, which can cause re-infection and infect other people. It is therefore strongly recommended that all members of the family (except pregnant and breastfeeding women and children under two) are treated at the same time and that precautions are taken to prevent re-infection.

For further information see the enclosed leaflet.

What are threadworm?

Threadworms (Enterovius vermicularis) are tiny white parasitic worms that live in the bowel. They are approximately half an inch long and resemble threads of white cotton - hence the name threadworms.

How common are threadworms?

Threadworms are extremely common, especially in childre. It is estimatedthat up to 40% of children under ten years in the UK may be affected at any one time. Once a child has threadworms, it is very easy for the rest of the family to get them.

How they spread?

Threadworms spread by producing large numbers of tiny eggs. These eggs are so small that they cannot be seen with naked eye. When swallod, the eggs pass into the bowel where they hatch into worms. When mature,m the female threadworm lays her eggs at night around the anal area, which causess an "ithcy bottom". The resulting irritation can cause intense scrathcing, which may lead further infections if the skin becomes sore or broken. Scratching allows transfer of the eggs to the fingers and nails. Eggs can be easily transferred to the mouth by finger sucking or nail biting, causing re-infection and spread to other members of the family by direct contact or via food, towels and bed linen, etc.

Threadworm eggs present in house dust, they stick in clothing, carpets, towels and bed linen.
