What is it
Ovex is a medicine which is used to treat threadworm (sometimes known as pinworm) infections of the gut. The tablet contains mebendazole, which is one of a group of medicines called ‘anthelmintics’. This medicine is for use in adults and children aged over 2 years.
What are threadworms?
Threadworms (Enterobius 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 children. It is estimated that 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.
