What is Vermox?

Vermox is a medication used to treat a worm infection in the gut, such as threadworms or other common worm infections (whipworm, roundworm, hookworm).

How does it work?

The active ingredient in this medication is called mebendazole and belongs to a group of medicines called anthelmintics. This medication works by stopping the worms from using the sugar (glucose) that they rely on to survive. Without this glucose, the cells of the worms lose their energy supply and will soon die. This medication will not, however, kill the eggs of the worms, so you need to take another dose two weeks later to help prevent any further infection.

Is Vermox suitable for me?

This medication is suitable for most adults and children over the age of 2. You should consult with a licensed medical professional if you have ever had an allergic reaction to mebendazole or any other medication or if you are pregnant or breastfeeding.
