COMBANTRIN® is only effective against adult worms, which means any eggs or immature worms inside the body might still linger after the initial treatment.
Visit your pharmacist if the infection continues two weeks after treatment. They may recommend a second dose of medication. In rare cases, mebendazole can cause abdominal pain or diarrhoea, particularly if the threadworm infection is severe.
Medicine will kill the worms in the gut, but not the eggs that have been laid around the anus. These can survive for up to 2 weeks outside the body on underwear, bedding etc. Good hygiene will clear any eggs from the body and the home, and prevent any eggs from being swallowed.
If you have tried a threadworm treatment for your child and their symptoms have not improved, take them to your GP. The doctor will examine your child and may want to do blood or faeces (poo) tests.
So it's advisable to follow-up on symptoms roughly 2-4 weeks after the initial dose, and administer a second dose if you detect any lingering signs of a worm infection. To learn more about the lifecycle of threadworms see our worm treatment page.

Medicine kills the threadworms, but it does not kill the eggs. Eggs can live for up to 2 weeks outside the body. There are things you can do to stop becoming infected again.
Treatment. The most commonly used anti-worm products to treat intestinal worms (threadworms, roundworms and hookworms) are pyrantel, albendazole or mebendazole.
The initial treatment of threadworms is essential, but leaving it there may be leaving the job unfinished! Threadworm eggs, laid around the anus, are untouched by treatments such as COMBANTRIN® or COMBANTRIN®-1 – and these eggs can hatch after the initial treatment, causing the infection to flare up all over again.
You'll likely need to give your doctor a stool sample for a few months to make sure all the worms are gone.
Treatment to get rid of worms
If you have worms, your GP will prescribe medicine to kill them. You take this for one to three days. The people you live with may also need to be treated. Any worms in your gut will eventually pass out in your poo.
A doctor or pharmacist may suggest you repeat the dose after 2 weeks to stop you from getting threadworms again. This is because the medicine kills the worms but not their eggs.
How long does it take for worms to leave a dog? Puppies will usually poop worms for a couple of days as the parasites die off between 2 and 14 hours. However, it's not unusual for worms to still be pooped out for up to a week after deworming.
Once you've given a dog dewormer, you may see worms in your dog's poop. Mostly they will be dead worms, but live ones can also be seen. It's crucial that you clean up these poops thoroughly and quickly, so your dog does not become reinfected.
This eventually leads to the worms dying within a few days. Once dead, the worms are then removed from the body by going through the gut and into the stool. However, this treatment threadworms only kills the adult worms and their eggs, so it's important to treat the whole family.
There are several reasons for worms to not move up. If it is too hot, the worms move down but will move back up when temperatures cool, however as it is winter, it probably isn't that reason. If you're putting too much new food in before they have eaten the previous food this can also cause worms to go down.
Avoid simple carbohydrates, such as those found in refined foods, fruits, juices, dairy products, and all sugars, except honey. Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites.
Pinworm eggs become infective within a few hours after being deposited on the skin around the anus and can survive for 2 to 3 weeks on clothing, bedding, or other objects.
So there's… autoinfection is huge. And we know that this is one of the main reasons why an infestation can become chronic. That it can actually go on for months and years because we're just never getting our head above water in terms of preventing those kinds of re-exposure risks.
If you take too much (overdose)
