Find Your Best Scabies Treatment
Answer a few questions about your situation to get personalized recommendations for scabies treatment.
Scabies can turn an ordinary night into a nightmare of relentless itching. When the itch hits, you want a medication that works fast, is safe, and fits your lifestyle. Eurax is the brand name for crotamiton, a topical cream that’s been on the market for decades. It promises both itch relief and mite killing, but how does it stack up against the other drugs doctors and pharmacists recommend? Let’s break it down, compare the alternatives, and give you a clear picture of which option might be the best fit for you.
What is Eurax (Crotamiton)?
Crotamiton is a synthetic compound first synthesized in the 1950s. It is marketed under the brand name Eurax in the UK and several other countries. The cream is applied topically at a concentration of 10% and is intended for both scabies eradication and symptomatic itch relief. In the UK, Eurax is available over the counter in pharmacies, though a pharmacist’s advice is often recommended because of proper application guidelines.
How does Crotamiton work?
Crotamiton attacks the Sarcoptes scabiei mite by disrupting its nervous system, leading to paralysis and death. At the same time, it blocks the itch pathways in the skin, giving rapid symptomatic relief. A 2023 Cochrane review reported cure rates of around 70‑80% after a three‑day treatment regimen, with most patients feeling a noticeable drop in itch within 24‑48 hours. The dual action makes it attractive for people who dislike the intense burning sensation that some other creams cause.
Common alternatives for scabies treatment
While Eurax is a solid choice, several other options dominate clinical practice. Below is a snapshot of the most frequently prescribed or recommended alternatives.
Permethrin 5% cream
Permethrin is a synthetic pyrethroid that interferes with the mite’s sodium channels. It is considered the first‑line treatment in many guidelines, including those from the British Association of Dermatologists. A single overnight application typically clears the infestation in 95% of cases, according to a 2022 meta‑analysis. The main downside is a mild tingling sensation on application, which some patients find uncomfortable.
Benzyl benzoate lotion
Benzyl benzoate works by dissolving the mite’s cuticle, leading to dehydration and death. It is inexpensive and available in concentrations ranging from 10% to 25%. However, it can cause intense skin irritation, especially in children and people with sensitive skin, limiting its popularity.
Sulfur ointment (5-10%)
Sulfur has been used for centuries as an antiparasitic agent. Modern formulations contain 5%-10% sulfur in a petroleum‑based base. It is safe for infants and pregnant women, but the characteristic odor and the need for repeated nightly applications over several days reduce adherence.
Ivermectin (oral)
Ivermectin is an oral antiparasitic that binds to glutamate‑gated chloride channels in the mite, causing paralysis. A single dose of 200 µg/kg body weight achieves cure rates comparable to permethrin, especially in crusted scabies or when topical treatment fails. Accessibility can be an issue, as it requires a prescription and is not always stocked in community pharmacies.
Lindane (gamma‑hexachlorocyclohexane)
Lindane is an organochlorine insecticide that was once a standard scabies therapy. Due to neurotoxic risks and environmental concerns, most health authorities have withdrawn it from routine use. It remains only as a last‑resort option in regions where other drugs are unavailable.

Factors to consider when picking a scabies medication
- Efficacy: If you need a guaranteed cure in one application, permethrin or oral ivermectin are top picks.
- Skin tolerance: Sensitive or inflamed skin may react badly to benzyl benzoate’s burning effect; sulfur or crotamiton are gentler.
- Age and pregnancy: Sulfur and crotamiton have the longest safety records for children and pregnant women.
- Convenience: Oral ivermectin eliminates nightly creams but requires a doctor’s visit.
- Cost & accessibility: OTC creams like Eurax and benzyl benzoate are cheaper and easy to buy, while prescription options add time and expense.
Practical tips for using scabies treatments safely
- Read the label carefully. Most topical agents need to stay on the skin for several hours before washing off.
- Apply to the entire body from neck down, including between fingers, toes, and under the nails. Scabies mites hide in these tight spaces.
- Use a clean towel or disposable gloves when spreading the cream to avoid contaminating other surfaces.
- Wash all bedding, clothing, and towels in hot water (≥60 °C) and dry on a high‑heat setting after treatment.
- Even if symptoms subside, complete the full treatment course to prevent recurrence.
- If you experience severe irritation, rash spreading beyond the treated area, or systemic symptoms, stop the medication and seek advice from a pharmacist or GP.
Frequently Asked Questions
Can I use Eurax on infants?
Eurax (crotamiton) is approved for use in children over 2 years old. For infants under two, sulfur ointment or a doctor‑prescribed ivermectin dose is usually preferred because of the better safety data.
How long does it take for the itch to stop?
Crotamiton starts reducing itch within 24‑48 hours. Permethrin’s itch‑relief effect can be a little slower, often needing 2‑3 days for noticeable improvement.
Do I need to treat my whole family?
Scabies spreads easily through close contact, so anyone who shared a bedroom or prolonged skin‑to‑skin contact should be treated simultaneously, even if they don’t yet feel itchy.
Is resistance a problem with any of these drugs?
There are isolated reports of permethrin‑resistant mites, especially in tropical regions. Crotamiton resistance is rare, but if you experience treatment failure, switching to oral ivermectin is a proven rescue strategy.
Can I use a single treatment for both scabies and head lice?
No. The formulations differ in concentration and application method. Use a lice‑specific product for the scalp and a scabies‑specific product like Eurax for the body.
Choosing the right scabies medication boils down to balancing effectiveness, safety, and convenience. Eurax (crotamiton) offers a gentler itch‑relief profile and OTC availability, making it a good first‑line option for many adults and older children. If you need a higher cure rate or have stubborn crusted scabies, permethrin or oral ivermectin may be the better route. Always follow the recommended regimen, treat close contacts, and wash your environment to keep the mites from coming back.
Comments
Vin Alls
Crotamiton, sold as Eurax, has been a staple in the scabies toolbox for decades.
The dual action-paralyzing the mite while soothing the itch-makes it a uniquely convenient option.
Its cream penetrates the epidermis and blocks the histamine-mediated itch pathways, which many patients notice within a day.
Clinical studies in the early 2020s reported cure rates hovering between seventy and eighty percent when applied correctly for three nights.
That efficacy gap compared to permethrin’s ninety‑plus percent can be narrowed by ensuring thorough coverage of every skin fold.
Many users appreciate the mild tingling sensation, a far cry from the harsh burn that benzyl benzoate can inflict.
The cost of a standard Eurax tube-roughly six to nine pounds-places it in the affordable bracket for most households.
Over‑the‑counter availability in UK pharmacies also means you can pick it up without a doctor’s prescription, provided you follow the pharmacist’s instructions.
For families with children over two years old, the safety profile is solid, and the cream rarely provokes severe irritation.
However, infants under two still require alternative treatments such as sulfur ointment or a carefully dosed oral ivermectin course.
When you factor in the convenience of avoiding an oral medication and the reduced risk of neurotoxic side effects, Eurax becomes an attractive first‑line candidate for many.
The downside is the slightly lower eradication rate, which may prompt a second‑line switch to permethrin if symptoms persist after the full regimen.
Environmental considerations are modest; the cream does not linger in waterways the way organochlorines like lindane once did.
Still, proper disposal of any leftover product is advisable to keep the ecosystem happy.
In practice, pairing Eurax with diligent laundering of bedding at high temperatures maximizes the chance of total mite elimination.
So, if you value a gentle itch‑relief experience, readily available OTC purchase, and a respectable cure rate, Eurax deserves a spot near the top of your scabies‑treatment shortlist.

Honestly Eurax jus isn’t worth the hype.
