Pinworms in Children in Brampton: Signs, Treatment and Household Steps

Some parents first hear about pinworms when their child cannot settle at bedtime, wriggling and scratching their bottom. Others notice something unexpected during a diaper change or a bath. Either way, the discovery tends to bring a mix of surprise and embarrassment. Worms? Really?

Pinworms, also called threadworms, are one of the most common intestinal infections in school-aged children. They spread easily in classrooms, child care centres and homes, and they have nothing to do with how clean a family is. While they are unpleasant and can disrupt sleep, they are generally harmless and treatable.

Ontario pharmacists can assess pinworm infections as part of their minor ailment services. At Pharmasave BramNorth, 25 & 26 - 2 Dewside Drive, you can ask about our pinworm service. This article walks you through the basics so you know what to look for and what to expect.

Meet the pinworm

Pinworms are tiny, thin, white worms, roughly the length of a staple. They live in the lower part of the intestine. At night, while the child sleeps, female worms move to the skin around the anus to lay their eggs. This is what causes the characteristic itch.

The eggs are microscopic and sticky. When a child scratches, eggs get under the fingernails and onto the fingers. From there, they can be transferred to the mouth, to food, to toys, to bedding and to other people. Once swallowed, the eggs hatch in the intestine, and the cycle begins again. Eggs can survive on surfaces such as bedding, clothing and toilet seats for up to a couple of weeks.

Because the life cycle depends on eggs being swallowed, breaking that hand-to-mouth route is just as important as treatment.

Signs that suggest pinworms

Many people with pinworms have no symptoms at all. When symptoms are present, they may include:

• Itching around the anus, usually worse at night.
• Restless sleep, waking during the night or difficulty settling.
• Irritability during the day, possibly from poor sleep.
• In girls, itching or irritation around the vaginal area, since worms can sometimes migrate there.
• Visible worms, which look like small pieces of white thread, around the anus at night or occasionally in stool.

Scratching can sometimes cause the skin to become raw or, less often, infected. If you see redness, swelling or discharge, mention it when your child is assessed.

How to confirm it: the tape test and night check

Two simple methods can help confirm pinworms:

The night check. A couple of hours after your child falls asleep, gently separate the buttocks and use a flashlight to look for small white worms around the anus. They move, which can help distinguish them from lint.

The tape test. First thing in the morning, before your child uses the toilet or bathes, press a piece of clear adhesive tape against the skin around the anus, then stick it onto a clean glass slide or a sealed plastic bag. This may pick up eggs, which can be seen under a microscope. Your doctor’s office or pharmacist can tell you whether they want this sample and how to provide it. Repeating the test on a few mornings increases the chance of finding eggs.

Even if you do not do a test, describing the symptoms clearly to a pharmacist or doctor is often enough for them to make a decision about treatment.

Treatment options and what to expect

Pinworms are treated with medicine that kills the worms in the intestine. In Canada, there are both non-prescription and prescription options. A pharmacist can assess your child, explain which treatment is suitable based on their age, weight and health, and make sure you understand how to use it.

A few points are common to most treatment plans:

• A second dose is often needed. Medicines kill the adult worms but not always the eggs. A repeat dose, typically about two weeks after the first, catches worms that hatched in the meantime. Follow the specific instructions you are given.
• Household members may need treatment. Because pinworms spread so easily, the whole household is often treated at the same time, even those without symptoms. A pharmacist will advise who in your home should be treated and whether any family members, such as very young children or pregnant individuals, need a different approach.
• Itch may continue briefly. It can take a few days after treatment for the itching to settle.

Do not use leftover medicine from a previous infection or from another family member without checking with a pharmacist first.

Hygiene habits that break the cycle

Medicine alone is not enough if eggs keep getting swallowed. These habits help stop reinfection:

• Wash hands well, with soap and warm water, especially after using the toilet, after changing diapers and before eating. Scrub under the fingernails.
• Keep fingernails short and discourage nail biting and thumb sucking where possible.
• Shower or bathe every morning during treatment to remove eggs laid overnight. Showers are preferable to shared baths.
• Change underwear daily, and have your child wear snug-fitting underwear or pyjamas at night to reduce scratching.
• Avoid shaking bedding, which can spread eggs into the air.
• Clean toilet seats and bathroom surfaces regularly during treatment.

Laundry and cleaning: what really helps

Pinworm eggs can live on fabric and surfaces for some time, so a bit of extra cleaning during treatment is worthwhile. However, you do not need to deep-clean your entire home.

Focus on:

• Washing bedding, pyjamas, underwear and towels in hot water after the first treatment dose, and again around the time of the second dose.
• Drying laundry on a hot setting.
• Vacuuming or damp-mopping bedroom floors.
• Wiping toys, especially those that go in the mouth, door handles and taps.

Do not use insecticide sprays; they do not help with pinworms.

Talking to children about worms

Children may feel embarrassed or worried. Explain in simple terms that pinworms are tiny germs that lots of children get at school, that they are not dangerous, and that the medicine and handwashing will get rid of them. Avoid making them feel dirty or at fault.

Turning handwashing into a game, singing a song while scrubbing or using a fun nail brush, can help younger children get into good habits. Praise them for washing well.

Whether to tell the school is your choice. Many schools and child care centres do not require children with pinworms to stay home, but some appreciate knowing so they can encourage handwashing in the class. Check your school’s policy if you are unsure, and Peel Public Health’s website has general information on common childhood infections.

When pinworms keep coming back

Reinfection is common, especially with school-aged children who are exposed again in class. If pinworms keep returning, consider the following:

• Was the second dose taken at the right time?
• Were all household members treated as advised?
• Were hygiene measures followed consistently, especially morning showers and handwashing?
• Could your child be picking them up from a friend, cousin or caregiver’s home?

If repeated infections occur despite careful treatment, speak to your doctor. They may want to look for other causes of the itch or arrange further testing.

When to see a doctor instead

A pharmacist can assess and manage many pinworm infections. However, some situations call for a doctor’s assessment, including:

• Symptoms in a very young child, outside the age range for the available treatments.
• A pregnant or breastfeeding family member who needs treatment.
• Signs of skin infection around the anus, such as swelling, pus or significant pain.
• Abdominal pain, weight loss or blood in the stool.
• Vaginal symptoms such as discharge in a girl.
• Repeated infections that do not respond to treatment.

The Ontario College of Pharmacists explains the conditions pharmacists can assess, and the pharmacist will refer you when an issue falls outside their scope.

Practical support from our pharmacy

When a pinworm infection hits, several family members may need treatment at once. Our pharmacists can help you work out who needs what, when the second dose is due, and how to measure doses for children. If a family member takes regular medicines, we will check for interactions. Ask whether there is any fee for the assessment when you call.

If you are already managing several family prescriptions, our prescription refill service can help keep everything on schedule.

A common mistake: stopping once the itch is gone

One of the most frequent reasons pinworms return is that families feel the problem is solved after the first dose. The night-time scratching settles, the child sleeps through, and the second dose is forgotten or skipped. But eggs that were already swallowed can still hatch in the following days, and without that repeat dose the cycle quietly starts again.

A simple fix is to mark the date of the second dose on the family calendar or set a phone reminder the same day you give the first one. Keep up the morning showers and handwashing until after the second dose, too. If you are unsure whether the timing still works because a dose was delayed, ask the pharmacist before giving it rather than guessing.
