One tablet for the worm, not one tablet for the house myth
Vermox 100 mg uses, in the US, now read as Emverm 100 mg chewable. Pinworm is one tablet once. Adults and children two and older share that count. No fasting, no purge.
Household treatment is common clinical practice because eggs travel on hands and bedding. The labelled dose is still one 100 mg tablet per infected person, not a shared half-tablet.
The tape-test plan is the morning diagnosis note. The course draft is the three-week calendar.
Emverm 100 mg chewable is the US mebendazole product, 21 August 2026. There is no approved generic. GoodRx lists 100 mg x 6 chewables at $5,386.85 average retail and $3,904.78 with a coupon. A two-tablet pinworm pair is a shorter count - this plan will not invent that cell. Manufacturer savings may apply if the patient has commercial cover. Yvessa does not dispense.
When 100 mg twice a day for three days is the real course
Trichuris, Ascaris, Ancylostoma, and Necator use the three-day morning-and-evening schedule. A single pinworm swallow is the wrong course for those infections.
Mixed infections follow the longer schedule. Stool exams, not a school note, decide that.
Plasma levels after 100 mg twice daily for three days stay tiny - on the order of 0.03 mcg/mL for parent drug in the label's older kinetic note. Activity is in the gut lumen. Metabolites are not anthelmintic.
| Absorption | Chew, swallow, or crush into food. No purge. |
|---|---|
| Distribution | Very low systemic levels at labelled gut doses. |
| Metabolism | Primary metabolite 2-amine; inactive against worms. |
| Excretion | ~2% in urine; remainder in feces as drug or metabolite. |
Return-to-class is local law, not a tablet timer
Some schools want 24 hours after the chewable. Some want a letter. Some want nothing if hygiene is documented. This Geneva desk does not set Vaudois or US district policy.
A child who chews 100 mg at 08:00 is not 'egg-free' at 09:00. Eggs on the collar last longer than the gut worms.
Under-twos in the same class still cannot use Emverm. Their plan is hygiene and a paediatric visit.
A six-count box is not a classroom kit. One indicated person, one 100 mg, unless a clinician wrote a household list.
How a tape test earns the 100 mg
Press clear tape on the perianal skin first thing, before a wash or a bowel movement. Stick the tape on a slide or the kit the clinic uses. Eggs show under a low-power lens more often than a random afternoon swab.
A negative tape on one morning does not close the case if the itch is classic and a household member is already positive. Three morning tests raise the yield. This sheet will not invent a sensitivity percent the label does not give.
Treating without any confirmation is how six-count boxes get used as anxiety medicine. The tape-test plan is the short card for school letters.
Night itch alone can be eczema or thread-from-wool. Look, then chew.
Pregnancy wording stays on the current leaflet
Older mebendazole texts advise against first-trimester use unless benefit wins. Newer packs may phrase it differently. The person who writes the script reads today's leaflet.
Hygiene and treatment of other household members can still proceed. A pregnant person does not have to chew 100 mg for the house plan to start.
Do not borrow an albendazole pregnancy sentence onto this chewable. Different benzimidazole, different label.
If 100 mg was chewed before the person knew, call the prescriber rather than reading a forum risk table.
No fasting, no laxative, no half-tablet maths
The label says no special procedures. People still starve a child or add a purge 'to help the worm out'. That is extra harm, not extra efficacy.
Crushing into food is allowed. Sharing a half with a sibling is not a labelled dose. Each indicated person two and older gets 100 mg.
Vomiting right after a chewable is a prescriber call, not an automatic second tablet from the six-count.
A school 'treat everyone Monday' campaign still needs a clinician for under-twos and for anyone pregnant. Hygiene does not need a prescription and should not wait.
Hookworm anemia is a three-day BID story plus iron follow-up. A leftover pinworm chewable does not treat that.
Quote six-count cash or ask the window. Do not invent a two-tablet cell because the course looks short.
Vermox on an old Swiss box and Emverm on a US receipt are trade-dress differences. The pinworm row is still one 100 mg. The other worms are still three days, morning and evening.
A classmate with itch is not a diagnosis. Tape first when you can. Hygiene does not wait for the tape.
If the six-count is what the window will sell, that is a supply fact, not a reason to chew extra tablets 'so they do not expire'.
Keep unused chewables out of a toddler's reach. The age-two floor exists because this is still a drug, even when the swallow looks like a sweet.
A three-week calendar on the fridge beats a memory of 'we took something in March'. The course draft is that calendar.
If two children share a bedroom, wash both sets of bedding even if only one chewed 100 mg. Eggs do not respect bed assignments.
Trim nails the same morning as the chewable. That five-minute job prevents a lot of three-week repeats later on.
Enterobius is a single swallow - then hygiene
Pinworm females lay eggs on the perianal skin at night. Itch leads to hand-to-mouth spread and to household clusters. A single 100 mg mebendazole dose kills worms in the gut. It does not sterilise eggs already on pyjamas.
The label's second course at three weeks is for people who are not cured - newly hatched worms, not a failure of the first chewable. Some public-health sheets repeat at two weeks. This desk follows the Emverm three-week sentence unless a clinician writes otherwise.
Morning tape test before washing or toileting is how schools and clinics confirm. Treating 'because a classmate had it' without a plan is how unused 100 mg tablets pile up.
| Infection | Emverm schedule | Same for age ≥2? |
|---|---|---|
| Pinworm | 1 tablet once | Yes |
| Whipworm | 1 tablet morning and evening × 3 days | Yes |
| Roundworm | 1 tablet morning and evening × 3 days | Yes |
| Hookworm | 1 tablet morning and evening × 3 days | Yes |
How to give the 100 mg without a fight
Chew it. Or swallow it. Or crush it into a spoon of food. Those three are labelled. Hiding a half in yogurt for a toddler under two is not.
No special diet the day of the dose. The course draft is the calendar for the possible three-week repeat.
If vomiting empties the stomach immediately, call the prescriber rather than redosing from a six-count box on a guess.
What the chewable can still do wrong
Abdominal pain, diarrhea, and rash appear in labelled adverse lists. Serious hypersensitivity is a stop. Seizures have been reported in postmarketing use, including in infants who should not have received the product.
Pregnancy: older mebendazole leaflets advise against first-trimester use unless the clinician decides benefit wins. This sheet will not invent a category. The prescriber reads the current leaflet.
Hepatic impairment can raise systemic exposure on longer courses. Pinworm's single tablet is a smaller systemic story than a three-day twice-daily course.
Carbamazepine and phenytoin can lower mebendazole levels. Cimetidine can raise them. Those matter more on multi-day courses.
This is not a Strongyloides sheet
Mebendazole's labelled worms are pinworm, whipworm, ascaris, and the two common hookworms. Strongyloides and onchocerciasis are other drugs. Do not borrow an ivermectin mcg/kg sentence onto a 100 mg chewable.
Travel stool plus eosinophilia is a clinic workup, not a leftover pinworm tablet.
Pinworm lock - easy mistakes
- Age <2 years: not indicated
- Do not share half-tablets
- Do not invent a 2-tablet GoodRx cell
- Three-day BID is not optional for ascaris
Why the second 100 mg exists
Mebendazole kills worms in the gut. Eggs already on skin, underwear, and door handles hatch on their own clock. The three-week second course is for that hatch, not for a 'weak first tablet'.
A household that chews 100 mg and skips the wash will meet the eggs again. Hot wash, morning shower, nails, daily underwear - those sentences belong on the same page as the chewable.
Schools sometimes demand a same-morning 'cleared' note. Eggs do not read notes. Local policy still wins. This desk will not write a fake clearance time.
Mixed stool diagnoses need the three-day morning-and-evening row. Do not stretch a pinworm single swallow across ascaris because the box is expensive.
Brand-only US supply is why cash shock happens. Quote the published six-count or ask the window for a two-count. Do not invent the two-tablet dollar on a uses page.
Children under two stay off Emverm. Crushed leftover 100 mg in toddler applesauce is how labelled age floors get ignored.
Carbamazepine and phenytoin can lower levels on longer courses. Tell the neurologist if the three-day schedule is in play.
Brand-only in the US - and a six-count quote
There is no approved US generic mebendazole chewable at the time this lock was written. Emverm is the product. Vermox branding still appears in older and non-US leaflets, which is why the page title keeps that search phrase.
GoodRx's published default is 100 mg x 6 chewables. A two-tablet pinworm pair is a shorter count. This plan will not invent that cell. Manufacturer programs may apply with commercial cover. Ask the window.
Yvessa does not dispense. A Geneva reader needs a local prescription and a local product name.
| INN / lock | Mebendazole / Emverm 100 mg chewable |
|---|---|
| Pinworm | 1 × 100 mg |
| Second look | 3 weeks if not cured |
| US generic | None approved |
| Quoted cash row | 100 mg x 6 - not a 2-count |
Margin notes on the 100 mg chewable
Vermox branding in a Swiss leaflet and Emverm on a US receipt are the same INN story with different trade dress. Dose table still wins.
Do not invent a two-tablet GoodRx cell because pinworm is 'only two swallows'. The published default is six.
Seizure reports in infants are why the age-two floor is not a suggestion.
Cimetidine can raise levels on multi-day courses. Pinworm's single tablet is a smaller version of that footnote.
The chewable does not wash the sheets
Morning shower, trimmed nails, daily underwear change, and a hot wash of bedding cut reinfection. That work sits beside the 100 mg, not after it as an optional extra.
Treat household members when the clinician says the cluster is likely. Each person still gets a full 100 mg, not a split tablet.
Children under two are outside the Emverm indication. Do not crush a leftover adult tablet into toddler food on a web page's advice.
