Treatment Comparison Results
Scabies outbreaks spike every summer, and the race to find the fastest, safest relief can feel endless. If you’ve grabbed a tube of Eurax Lotion and are wondering whether it truly beats the alternatives, you’re in the right place. Below you’ll find a side‑by‑side look at the most common scabies medicines, real‑world usage tips, and the decision points that matter for everyday people.
Key Takeaways
- Eurax Lotion (crotamiton) offers decent relief for mild itching but is slower to kill the mite than permethrin.
- Permethrin 5% cream remains the global first‑line therapy because it works quickly and has a low irritation profile.
- Older options like lindane and benzyl benzoate are still sold in some pharmacies but carry higher skin‑sensitisation risks.
- Oral ivermectin is a good backup for extensive infestations or when topical agents fail.
- Price, availability in New Zealand, and personal skin tolerance should guide your final pick.
How Crotamiton (Eurax Lotion) Works
Eurax Lotion is a topical scabicide that contains the active ingredient crotamiton (1% w/w). Crotamiton works by paralyzing the Sarcoptes scabiei mite and simultaneously soothing the intense itch that the infestation triggers.
The lotion is applied from the neck down, left on for 24hours, then washed off. A second application 24hours later is usually recommended for a complete cure. Because it also has antipruritic (itch‑relieving) properties, users often notice less scratching within a day, even though the mite‑killing action may take up to 48hours.
Common Alternatives: What’s on the Shelf?
While Eurax is convenient, several other scabicides dominate pharmacy shelves worldwide. Below is a quick snapshot of each, followed by a deeper dive.
- Permethrin 5% Cream - a synthetic pyrethroid that attacks the mite’s nervous system, killing it within hours.
- Benzyl Benzoate Lotion (10‑25%) - an oil‑based scabicide that dissolves the mite’s cuticle but can sting skin.
- Lindane Cream (1%) - a once‑popular organochlorine with strong neurotoxic potential; now restricted in many countries.
- Ivermectin Tablets (200µg/kg) - an oral antiparasitic taken as a single dose, useful for severe or crusted scabies.
- Malathion Lotion (0.5%) - a pesticide‑derived lotion rarely used today because of irritation risk.

When to Choose Eurax Lotion Over Other Options
If you have mild to moderate scabies, a normal skin barrier, and a preference for a product that also soothes itching, Eurax can be a solid first choice. Its two‑day regimen is easy to remember, and the lotion format spreads evenly over large body areas.
However, consider permethrin if you need rapid mite eradication-especially when you have close contacts (family, school kids) and want to cut the transmission window. Permethrin’s faster kill time also reduces the risk of secondary bacterial infection from scratching.
Older agents like benzyl benzoate or lindane are best reserved for cases where newer products are unavailable or when a patient has documented intolerance to permethrin. Their higher irritation rates mean they should be applied under medical supervision.
Oral ivermectin shines in crusted scabies, immunocompromised patients, or when the entire household shows infection despite proper topical use. It bypasses skin absorption issues entirely.
Side‑Effect Profile: What to Watch For
All scabicides can cause some local irritation; the key is how severe and how common the reaction is.
- Eurax Lotion - mild redness, dry patches, rarely a rash. Because it also dampens itching, many users report fewer scratches.
- Permethrin - brief burning or tingling that fades within a few hours; rare allergic reactions.
- Benzyl Benzoate - noticeable stinging at the time of application; may trigger dermatitis in sensitive skin.
- Lindane - can cause intense burning, and systemic absorption raises concerns of neuro‑toxicity; hence restricted.
- Ivermectin - systemic side effects (headache, mild fever) but usually well tolerated; contraindicated in pregnancy.
If any product causes worsening redness, swelling, or blistering, stop use immediately and seek advice from a pharmacist or doctor.
Pricing, Availability, and Practical Tips for 2025 New Zealand
Pharmacies across Auckland stock permethrin and Eurax as over‑the‑counter options. Benzyl benzoate is often found in bulk‑buy health stores, while lindane requires a prescription due to regulatory limits. Ivermectin is listed on the Pharmaceutical Schedule and can be obtained with a doctor's script.
Practical tips:
- Read the label carefully-some lotions (e.g., benzyl benzoate) need a “wash‑off” after 12hours, while Eurax stays on for 24hours.
- Apply to clean, dry skin. For children, avoid the scalp and face unless directed.
- Use a clean towel or disposable gloves to spread the product evenly; this reduces cross‑contamination.
- Wash all clothing, bedding, and towels in hot water (≥60°C) and dry on high heat to prevent re‑infestation.
- Check the expiration date-some older stock loses potency after two years.
Bottom Line: Picking the Right Scabicide for You
In a nutshell, Eurax Lotion offers a balanced mix of mite killing and itch relief, making it a comfortable option for many households. If speed is critical or you have a history of treatment failure, permethrin remains the gold standard. Reserve the harsher chemicals (benzyl benzoate, lindane) for limited cases where newer meds are truly inaccessible. And keep oral ivermectin in the back‑up kit for severe or resistant infections.
Frequently Asked Questions
How long does Eurax Lotion stay on the skin?
The first application is left on for 24hours, then washed off. A second dose is applied 24hours later and left on for another 24hours before washing.
Can I use Eurax Lotion on children under 2 years?
Manufacturers advise against use on infants younger than 2years. For younger kids, permethrin 5% cream is usually the recommended option, but always consult a paediatrician.
Is it safe to treat the whole family with the same product?
Yes, scabies spreads easily, so treating all close contacts at the same time reduces reinfestation risk. Just follow the age‑specific instructions on the label.
What should I do if my skin reacts badly to a scabicide?
Stop using the product, rinse the area with mild soap and water, and apply a fragrance‑free moisturizer. If redness, swelling or blisters persist, see a pharmacist or doctor for alternative treatment.
Do I need to repeat treatment if symptoms persist after two applications?
If itching continues beyond a week after the second dose, it may be a secondary infection or a resistant mite strain. Consult a healthcare professional-oral ivermectin or a second‑line topical may be prescribed.

When you’re dealing with a scabies outbreak, the first thing to keep in mind is consistency. Apply Eurax Lotion exactly as the label directs-24 hours on, wash off, then repeat the next day. This two‑day schedule gives the crotamiton enough time to paralyze the mites while also soothing the itch. Make sure the skin is clean and dry before you spread the lotion; a bit of soap residue can dilute the product. Using a clean towel or disposable gloves helps you get an even layer without re‑contaminating. After each application, wash all bedding, towels, and clothing in hot water (at least 60 °C) and tumble dry on high heat. That step is crucial because the mites can survive in fabrics for several days. If you have any mild redness, it’s usually just a transient reaction-don’t panic, just keep the area moisturised with a fragrance‑free lotion. For families, treat every close contact at the same time; scabies spreads quickly, and staggered treatment often leads to reinfestation. Finally, check the expiration date; older stock may have lost potency, which can make the whole process drag on much longer. Stay diligent, and you’ll see the itching subside within a week after the second dose.
Think of scabies management as a collective well‑being practice rather than a solo battle. While Eurax offers both anti‑mite and antipruritic benefits, the broader context includes hygiene, environmental cleaning, and community awareness. It’s worth noting that the moderate itch relief from crotamiton can be a comfort for those who struggle with sleep disruption. At the same time, the slower kill time (24‑48 hours) may prolong the window for transmission, so combining treatment with thorough laundering is essential. From a philosophical standpoint, treating the whole household at once respects the interconnected nature of our skin ecosystems. Remember that a calm, supportive environment can reduce the stress‑induced scratching that often worsens skin lesions. In practice, set a simple schedule: day one application, day two repeat, and monitor for side effects. If irritation emerges, a short course of a mild corticosteroid cream can help, but always consult a pharmacist first. Ultimately, the goal is not just eradication but restoring comfort and confidence in daily life.
From a formal perspective, it is advisable to compare the pharmacodynamics of each scabicide before selection. Crotamiton operates by paralyzing Sarcoptes scabiei, whereas permethrin disrupts the mite’s neuronal sodium channels, resulting in a faster kill time of 2‑4 hours. The slower action of Eurax may be acceptable for patients with mild infestations and a preference for simultaneous itch relief. However, it is essential to acknowledge that the skin’s barrier function can influence absorption rates; therefore, applying the lotion on dry, intact skin maximizes efficacy. In addition, the side‑effect profile of Eurax-mild erythema and dryness-is generally less severe than the stinging reported with benzyl benzoate. For individuals with a history of dermatitis, the antipruritic component may reduce secondary infection risk. Ultimately, the decision should be guided by clinical presentation, patient tolerance, and local availability of over‑the‑counter options.
It is important to question the conventional wisdom that Eurax is a universally safe choice. While the packaging claims “mild redness” as a side effect, reports of allergic contact dermatitis have surfaced in niche dermatology forums, suggesting a possible under‑reported issue. Moreover, the regulatory bodies in several countries have limited the distribution of crotamiton due to concerns over suboptimal mite kill rates compared to permethrin. If you are considering Eurax for a household with children under two, the manufacturer’s warning should not be taken lightly; the risk‑benefit ratio shifts when infant skin is more permeable. An alternative, such as a prescription‑only lindane, carries neuro‑toxicity concerns but offers a rapid kill time; this paradox highlights the need for informed consent rather than blind reliance on “over‑the‑counter” labeling. Therefore, always verify the latest pharmacovigilance data before committing to a treatment plan.
