CKS is no longer commissioned by the National Institute for Health and Clinical Excellence (NICE). NICE remains committed to providing a replacement service for CKS and is currently reviewing its options. In the meantime, although CKS content is now not being maintained, it still remains relevant and will continue to be made available. CKS content was generated under a programme of topic creation and update.

Scabies - Management
How should I manage someone presenting with scabies?
- Simultaneously (within 24 hours) treat all members of the household, close contacts, and sexual contacts with a topical insecticide (even in the absence of symptoms).
- Encourage the family not to delay treatment.
- Pregnant or breastfeeding women should also be treated with an insecticide.
- Apply the insecticide twice, with applications one week apart.
- Consider symptomatic treatment for itching:
- Advise the person that itching may take several weeks to resolve.
- Treat associated eczema — see the CKS topic on Eczema - atopic.
- Treat scabies that has become infected with an antibiotic.
- Machine wash (at 50°C or above) clothes, towels, and bed linen, on the day of application of the first treatment.
- Advise the individual to avoid close body contact with others until their partners and close contacts have been treated.
Clarification / Additional information
- Keep any items of clothing that cannot be washed in plastic bags for at least 72 hours to contain the mites until they die.
- Pressing clothes with a warm iron, dry cleaning, or putting items in a dryer on the hot cycle for 10–30 minutes is also effective.
- It is not necessary to fumigate living areas or furniture, or to treat pets.
Basis for recommendation
- These recommendations are based on expert advice from the published medical literature [HPA, 2005; Johnston and Sladden, 2005; Fox and Usatine, 2006].
- It is important that all contacts (symptomatic and asymptomatic), including members from the same household, are treated on the same day:
- Scabies is highly contagious and there is a latent period before symptoms develop.
- Simultaneous treatment is important as this minimizes the chances of reinfestation from an untreated contact.
- The recommendation for two applications, 7 days apart, is an unlicensed use of permethrin, and is different to the packaging information which states that a single application is sufficient. Malathion is now licensed as a course of two applications of insecticide 7 days apart [ABPI Medicines Compendium, 2007].
