For threadworm treatment, UK OTC mebendazole starts near £4.50; in the US, OTC pyrantel is about $9–$15, while prescriptions can cost more.
Wondering what you’ll pay to sort a threadworm problem fast? Here’s a plain-English breakdown of pharmacy prices, what each medicine covers, and smart ways to keep the bill low. You’ll see real-world ranges for single adults, kids, and whole households, plus when a prescription makes sense and what that can run.
Cost Of Treating Threadworms — Typical Price Ranges
Two common routes exist: buy a pharmacy treatment or get a prescription. In the UK, mebendazole is sold over the counter for this infection. In the US, pyrantel pamoate is the main store option, while mebendazole and albendazole usually require a prescription. Guidance below sticks to what health agencies recommend, then maps costs you can expect at checkout.
Fast Price Snapshot (UK And US)
These figures reflect live retailer listings and price tools as of October 2025. One dose treats the person taking it; many homes treat everyone at once to cut reinfection risk.
| Option | Typical Price | What You Get |
|---|---|---|
| UK OTC mebendazole (single tablet) | ~£4.49 per tablet | One chewable tablet for one person; repeat in 2 weeks if advised. Source: Chemist4U live listing. |
| UK family pack mebendazole | ~£8.49 for 4 tablets | Four single-dose tablets for four people. Good value for households. |
| UK liquid mebendazole (family bottle) | ~£11.99 per bottle | Liquid form for those who prefer not to chew tablets. |
| US OTC pyrantel pamoate (single bottle) | ~$9–$15 per 1–2 oz | Store brand or Reese’s/Pin-X; dose by weight. Many bottles cover more than one person. |
| US prescription albendazole | $24+ with coupon; retail list can be far higher | Price swings widely by pharmacy and insurance; coupons drop the cost in many cases. |
Why ranges? Retailers run promos, and local taxes or shipping change totals. Liquid volumes differ by brand, and doses depend on weight or age.
What Each Medicine Is And When It’s Used
UK: Mebendazole Over The Counter
Pharmacists recommend a single 100 mg dose for threadworms, with a second dose two weeks later in some cases. Everyone aged 2+ in the same home often takes it on the same day. This plan pairs with strict hygiene for two weeks to break the cycle. Public guidance outlines that approach in plain terms.
US: OTC Pyrantel And Prescription Options
In the US, pyrantel pamoate is sold without a prescription and serves as the first stop for many families. Prescription routes include mebendazole and albendazole. A clinician may choose one of these based on age, pregnancy, or prior treatment. Health agency pages list all three and explain use cases.
Pregnancy And Young Children
Care changes during pregnancy and in very young children. Many clinicians lean on pyrantel during pregnancy and in kids under 2 years old. Always check with your healthcare provider or pharmacist first in these groups.
How To Estimate Your Real Out-Of-Pocket Cost
Step 1: Count People You Plan To Treat
Most homes treat everyone at once. If four people live together, buying a family pack in the UK cuts the cost per person. In the US, a single pyrantel bottle often covers several doses, but read the label and dose by weight.
Step 2: Match Form To The Person
- Chewable tablet: Simple one-and-done for most adults and older kids.
- Liquid: Handy for kids who won’t chew tablets; dosing can be precise.
Step 3: Factor A Second Dose
A second dose two weeks later is common in many plans. Budget enough tablets or liquid to repeat if advised. This second step helps catch worms that hatched after the first dose.
Step 4: Add Hygiene Supplies
You’ll spend a little on soap, extra laundry cycles, and disposable gloves. The medicine is the main cost; hygiene stops the ping-pong effect.
Where These Numbers Come From
For price points, this guide checks live pharmacy listings and trusted price tools. For treatment basics and who should take what, it uses public health pages used by clinicians. Two reliable, readable overviews are the NHS page on mebendazole and the CDC clinical overview of pinworm. Both outline one-dose treatment, second-dose timing, and household treatment.
How Much You’ll Likely Pay, Broken Down
Single Adult, UK
Pick one chewable tablet for about a fiver. Add a second tablet for day 14 if you plan to repeat. Many people just buy a twin or family pack so spares are on hand. A liquid bottle costs a bit more but suits those who dislike tablets.
Family Of Four, UK
The family pack with four tablets lands under a tenner at many online pharmacies. If you plan a repeat in two weeks for all four, buy two packs. Per-person cost drops compared with singles.
Single Adult, US
One bottle of pyrantel often falls near the $10–$15 mark and may cover more than one adult dose, depending on strength and volume. Check the dosing chart by weight. Store brands work the same way as name brands when the active ingredient and strength match.
Prescription Route, US
Prices jump here. Albendazole’s retail list can look steep, yet coupons through big chains bring a bottle far lower than the sticker price. Insurance plans vary widely. If a clinician prescribes it, ask the pharmacy to run a discount card quote before you pay.
Practical Ways To Keep Costs Low
Buy Smart For The Whole Household
Households often save with multipacks or higher-volume liquids when several people will take a dose. The label will show total volume and active strength so you can tally whether one bottle covers your group.
Pick Equivalents
Generic or store-brand pyrantel in the US uses the same active ingredient and can be cheaper. In the UK, different brands of mebendazole deliver the same dose for threadworms; pick the best price from a regulated pharmacy.
Use Coupons Or Price-Match Tools
For US prescriptions, coupon tools can slash out-of-pocket costs at the register. It takes a minute at the counter and can change the total in a big way.
What A Full Plan Looks Like
Medicine Plus Hygiene
Medicine kills the worms. Eggs are the reason homes see bounce-back. Pair your dose with simple daily steps for two weeks: morning showers, clean underwear and bedding, trimmed nails, and frequent handwashing. Public guidance stresses this combo because it stops repeat cycles across the home.
Repeat Dose Timing
Many plans repeat the dose at day 14. That timing lines up with the life cycle and helps mop up any late hatchers. Budget for the second dose at the start so you aren’t making a last-minute run.
UK And US Examples With Real Numbers
UK Examples
- One person: One tablet ~£4.49; add another tablet for day 14 and you’re still under £10.
- Four people: Family pack ~£8.49; two packs for two doses each keeps the total well under £20.
- Liquid route: A bottle ~£11.99; check the leaflet for how many millilitres per person.
US Examples
- One person with pyrantel: One bottle near $10–$15 covers the first dose; many bottles have enough for the second dose, too.
- Prescription albendazole: With a coupon, some pharmacies quote around $24 and up, while list prices without discounts can be far higher.
Safety Pointers That Save Money Too
Read The Leaflet
Dosing, age limits, and interactions live there. That avoids wasting a product that doesn’t fit your situation.
Ask A Pharmacist
If you’re pregnant, breastfeeding, dosing a toddler, or on other medicines, get a quick check at the counter. It’s free and speeds you to the right pick.
Treat The Group Once
When several people share a home, treating everyone on the same day reduces the chance of starting over later. That saves time and repeat costs.
Cost Scenarios You Can Copy
| Scenario | Items | Estimated Total |
|---|---|---|
| UK, Two Adults | 2 tablets now + 2 tablets at day 14 | ~£17 (buy two 4-packs and keep spares for next time) |
| UK, One Adult + Two Kids | 1 family pack of 4 tablets | ~£8.49 (repeat dose may need a second pack) |
| US, One Adult | 1 bottle pyrantel | ~$10–$15 (many bottles cover the day-14 repeat) |
| US, Two Adults + Two Kids | 1–2 bottles pyrantel | ~$10–$30 (depends on bottle size and weights) |
| US, Prescription Route | Albendazole with coupon | $24+ (plan and pharmacy make a big difference) |
When A Doctor Visit Makes Sense
See a clinician if symptoms persist after repeat dosing, if a child is under 2, during pregnancy, or if you notice signs that don’t match threadworms. Bring the box or bottle you used and note the dates you dosed.
