To remove threadworm eggs and prevent re-infection: Change and wash underwear, nightwear and, if possible bed linen and towels, every day for a few days. A hot water wash, or the heat of an iron, will kill the eggs.
Be sure to clean the skin around the anus. This will remove pinworm eggs. Showers may be better than baths because you have less chance of getting water that has pinworm eggs into your mouth.
"Changing and washing bedding can help to remove threadworm eggs within the linen," agrees Dr Luke Powles, clinical director at Bupa UK. "However, be careful when removing the sheets as shaking bedding around may cause the eggs to land on other surfaces and spread infection."
There are two ways of treating an infestation – either using the hygiene method or by taking medication in combination with hygiene measures. If, however you have a threadworm infection and you're pregnant, breastfeeding or you have a baby under three months old, always see your GP for advice.
The worms die after about six weeks. Provided that you do not swallow any new eggs, no new worms will grow to replace them. So, if you continue the hygiene measures described above for six weeks, this should break the cycle of re-infection, and clear your gut of threadworms.
Pay attention to kids' hygiene
Wash your hands regularly to avoid picking up the infection yourself, and encourage children to do the same, especially after using the toilet or playing outside. It also helps if fingernails are kept short and clean – longer nails can provide a great hiding place for the infection.
The worms will die after 6 weeks so provided you do not swallow any new eggs then no new worms will grow to replace them. Strict attention to hygiene should be sufficient. Piperazine (Pripsen) is a different medicine, and can be used in children under 2 years (but over 3 months).
If you have worms, a GP will prescribe medicine to kill them. You take this for 1 to 3 days. The people you live with may also need to be treated. Any worms in your gut will eventually pass out in your poo.
For the itching, wash the skin around the anus with warm water. For severe itch, use 1% hydrocortisone cream (such as Cortaid) 2 times per day. Use for 1 or 2 days. No prescription is needed.
The lifespan of threadworms is approximately 6 weeks, so it's important that hygiene measures are followed for at least this length of time. Everyone in the household must follow the advice outlined below.
Threadworms usually produce no symptoms except an itchy bottom. In fact, people may harbour them for years without realising it. Distaste aside, threadworms do no harm - except, as my GP wryly observed, to the sufferer's self-esteem. The worms are white and about a centimetre long by 0.5mm in diameter.
Threadworm is spread when children scratch their bottom, causing the eggs to collect under the fingernails. The child then carries the worm eggs back to their mouth with their hands. The eggs can also be spread indirectly, in food, dust, or other items. The eggs can survive up to two weeks outside the body.
Daily morning bathing and changing of underclothes helps remove a large proportion of pinworm eggs and can help prevent infection and reinfection.
Avoid shaking clothing and bedding to keep pinworm eggs from spreading through the air. Do not allow children to bathe together, as pinworm eggs can potentially spread in bath water and on washcloths.
It moves. If it doesn't wiggle, it's probably lint or a thread. The worm may be seen around the anus or on the child's bottom. It is especially active at night or early morning.
Threadworms. An itchy bottom that's worse at night is often caused by threadworms, especially in children. Children under 2, and pregnant and breastfeeding women, cannot usually take medicine for threadworms – see a GP, midwife or health visitor instead.
The most common symptoms of a threadworm can include: An itchy bottom. General irritability and behavioural changes. Trouble sleeping, or restless sleep, sometimes resulting in bed-wetting.
To remove threadworm eggs and prevent re-infection: Change and wash underwear, nightwear and, if possible bed linen and towels, every day for a few days. A hot water wash, or the heat of an iron, will kill the eggs.
How long does it take for worms to be gone after deworming? Once you take the deworming medicine, the medicine starts working immediately, but it might take a few days to kill all the worms. It is advised to take a second dose after two weeks to prevent reinfection.
Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites. In one study, researchers found that a mixture of honey and papaya seeds cleared stools of parasites in 23 out of 30 subjects. Drink a lot of water to help flush out your system.
Medications kill only the adult worms and have no effect on developing eggs and larvae. The prescription of choice is mebendazole* and the non-prescription medication of choice is pyrantel pamoate. Both mebendazole and pyrantel pamoate are given as a single dose and repeated in 2 weeks to kill any newly ingested eggs.
Symptoms of threadworm infection usually disappear within one week of treatment. Threadworms are highly contagious. Hygiene measures should be followed for 6 weeks.
This is why you may need to take another dose 2 weeks later to help prevent reinfection. How long does it take to work? The medicine should start to work straight away but it may take several days to kill all the worms. It's important to take the medicine as a pharmacist or doctor tells you.
