This medicine is for use in adults and children aged over 2 years.

You or your child has been advised to take Vermox suspension because you have a worm infection. Worms can infect anyone. It does not necessarily mean that your hygiene is poor.

7. Further advice regarding worms

Threadworms (pinworms) produce large numbers of tiny eggs. They may be present in house dust and can stick to clothing, carpets, towels and bed linen. They can also be picked up by contact with someone who already has worms. Because the eggs are so small, it is very easy for them to be swallowed. Then they pass into the bowel where they grow into worms. The female lays her eggs at night around the bottom. It is this that causes the "itchy bottom" and leads to scratching. The eggs are then transferred to the fingers and finger nails, and can easily get into the mouth by finger sucking or nail biting. The life cycle of an adult worm can be as long as six weeks.
