Pinworms and threadworms Treatment Online — Ontario Virtual Care

Pinworms (and the related threadworms) are tiny, thread-like parasitic worms that infect the intestines and are best known for causing intense itching around the anus, especially at night when the female worms come out to lay eggs -- which is also why disrupted sleep is such a common complaint. They spread very easily through microscopic eggs on hands, bedding, and surfaces, particularly among school-age children and household members, since scratching the itchy area and then touching food, toys, or other people continues the cycle. It's one of the most common parasitic infections in Canada, and while unpleasant, it's straightforward to treat once identified.

Quick Self-Check
Answer a few quick questions. This isn't a diagnosis — a real pharmacist assessment is the next step either way.
How We Work
A Care365 online pharmacist consult can confirm your symptoms fit the classic pattern of nighttime anal itching without other concerning features, then prescribe an antiparasitic medication along with the correct repeat-dose timing needed to fully clear the infection. The consult also covers the household hygiene steps -- like hot-washing bedding, short fingernails, and treating other family members -- that matter just as much as the medication for actually stopping reinfection.

Frequently Asked Questions
Why does the itching get worse at night?
Female pinworms migrate out of the anus to lay eggs at night, which is what triggers that intense nighttime itching -- it's one of the most recognizable signs of a pinworm infection.
Does everyone in the house need treatment, or just the person with symptoms?
Because pinworm eggs spread so easily between household members through shared surfaces and bedding, treating the whole household at the same time is usually recommended to fully break the cycle, even if only one person has symptoms.
Why do I need a second dose two weeks after the first?
The initial dose kills the adult worms but not necessarily any eggs already present, so a repeat dose about two weeks later clears any newly hatched worms before they can re-establish the infection.
My symptoms came back shortly after treatment -- did it not work?
Symptoms returning within two weeks of finishing treatment suggests either reinfection or that the treatment didn't fully clear things, and needs a different approach than simply repeating the same medication again.
Could this be something other than pinworms, like a food intolerance or allergy?
Straightforward pinworm infection doesn't typically cause abdominal pain, rash, or whole-body symptoms like fever or weight changes -- if you're having those, it's worth exploring other causes alongside or instead of pinworms.
