Things worth knowing about "Scabies treatment"
Scabies treatment targets the scabies mite using creams, lotions, or tablets. Learn which therapies are effective and how to prevent reinfestation.
What is scabies and why does it need treatment?
Scabies is a contagious skin condition caused by the scabies mite (Sarcoptes scabiei). These microscopic mites burrow into the outer layer of the skin, lay eggs, and cause intense itching along with characteristic skin changes. Without targeted treatment, scabies does not resolve on its own and can easily spread to other people. Prompt and thorough treatment is therefore essential.
Treatment options for scabies
Scabies is primarily treated with scabicidal agents — medications that kill mites. These are available as creams, lotions, or oral tablets. The choice of treatment depends on the patient's age, pregnancy status, and severity of infection.
Permethrin (first-line treatment)
Permethrin 5% cream is the most commonly recommended treatment for scabies. It is applied to the entire body surface from the neck down to the soles of the feet and washed off after 8 to 12 hours. Permethrin is considered safe for infants aged 2 months and older, and can be used during pregnancy under medical supervision. One to two applications are usually sufficient.
Ivermectin (oral therapy)
Ivermectin is an oral medication used particularly in cases of severe, crusted scabies (also known as Norwegian scabies) and in outbreak situations in care facilities or institutions. It is given as a single dose or in multiple doses. Ivermectin is not recommended for children weighing less than 15 kg or during pregnancy.
Benzyl benzoate
Benzyl benzoate (10–25%) is applied as a lotion and represents a cost-effective alternative used widely in many countries. Multiple applications are required, and skin irritation may occur.
Crotamiton
Crotamiton is available as a cream or lotion and acts both as a mite-killing agent and an anti-itch treatment. It is generally considered less effective than permethrin and is often used as a supplementary option.
Treating close contacts and the environment
Since scabies is highly contagious, all close contacts (e.g., household members, sexual partners) must be treated simultaneously, even if they show no symptoms. The following environmental measures are also important:
- Wash clothing, bed linen, and towels at a minimum of 60 °C, or seal them in a plastic bag for at least 72 hours (scabies mites can only survive a few days away from human skin).
- Place non-washable items (e.g., soft toys) in a sealed bag for at least 72 hours.
- Thoroughly vacuum mattresses, furniture, and carpets.
Itching after treatment
Even after successful treatment, itching may persist for 2 to 4 weeks. This is a normal reaction of the body to dead mites and their byproducts remaining in the skin. Antihistamines or mild corticosteroid creams can help relieve the itch. If itching continues beyond this period or new skin lesions appear, a doctor should be consulted to rule out reinfection.
When to see a doctor
If scabies is suspected, a doctor or dermatologist should be consulted promptly. Self-treatment without a medical diagnosis is not advisable, as scabies symptoms can resemble other skin conditions. Medical guidance is especially important for:
- Infants and young children
- Pregnant or breastfeeding women
- Immunocompromised individuals
- Suspected crusted (Norwegian) scabies
