More information
"Vermox is a widely trusted anthelmintic treatment primarily prescribed for enterobiasis, more commonly known as threadworms or pinworms. It is also used to manage other intestinal parasitic infestations such as whipworm, roundworm and hookworm. By preventing the parasites from absorbing essential nutrients, it effectively clears the infection when combined with strict household hygiene measures." - Rachael Clarke MRCPharm MFRPSI FRSPH (GPHC Number: 2061366)

Vermox is a brand name for mebendazole, a medication used to treat intestinal worm infections such as threadworms, which affect up to 40% of children in the UK at some point. It is effective against several types of parasites, including:
- Threadworms (Pinworms)
- Roundworms (Ascaris)
- Whipworms (Trichuris)
- Hookworms (Ancylostoma and Necator)
The active ingredient in Vermox is mebendazole, which belongs to a class of medicines known as benzimidazole anthelmintics. Each standard tablet typically contains 100mg of mebendazole, designed to work locally within the gastrointestinal tract to eliminate the parasites.
Vermox works by selectively and irreversibly blocking the worms from absorbing glucose, which is their primary source of energy. This depletion of glycogen causes the worms to lose their energy supply and die within a few days, after which they are naturally passed out of the body through bowel movements.
You should take Vermox exactly as directed by your prescriber or as outlined in the included instructions. The tablets can be swallowed whole, chewed or crushed for younger children, and they can be taken with or without food without affecting the efficacy of the medication.
The dosage of Vermox varies depending on the specific type of worm infection being treated, as shown in the table below:
| Infection Type | Standard Dose (Adults & Children over 2) |
|---|---|
| Threadworms (Pinworms) | A single 100mg tablet (repeat after 2 weeks if required) |
| Roundworm/Hookworm | 100mg twice daily for three consecutive days |
Most people use Vermox without experiencing significant issues, but like all medicines, it can cause side effects in some individuals. Common side effects may include:
- Mild stomach pain or abdominal discomfort
- Flatulence (wind)
- Diarrhoea
Vermox is not suitable for everyone, and you must inform your prescriber if you are pregnant or breastfeeding, as mebendazole is generally contraindicated during pregnancy. It should not be given to children under two years of age unless specifically directed by a doctor, and you should mention if you are taking other medications such as Metronidazole or Cimetidine.
Vermox is often preferred over other anthelmintics like piperazine because it is effective against multiple stages of the worm lifecycle and often requires a simpler dosing schedule for threadworms. While generic mebendazole is available, many patients choose the Vermox brand for its established reliability and the convenience of the chewable tablet format.
User experiences generally highlight the ease of use associated with the single-dose regimen for threadworms and the fast relief from symptoms like perianal itching. Most patients find the treatment highly effective, especially when the entire household is treated simultaneously to prevent the cycle of reinfection.
A Patient Information Leaflet (PIL) is included in every pack of Vermox and should be read thoroughly before starting your treatment. The PIL provides comprehensive details on ingredients, potential interactions and full safety instructions to ensure the medication is used correctly.
Do I need to treat my whole family?
Yes, health experts recommend treating every member of the household at the same time if one person has threadworms, even if they do not have symptoms, to prevent reinfection.
How long does it take for the worms to die?
The medication starts working immediately to stop the worms from absorbing sugar, and they typically die and pass out of your system within a few days.
Does Vermox kill worm eggs?
No, mebendazole only kills the adult worms. It does not kill the eggs. This is why strict hygiene and often a second dose after two weeks are necessary to clear the infection fully.
