Hi Stephen - sorry in the delay of response.  We have quite a bit of information on this subject of Scabies.

As you know, scabies is a mite infestation of the skin. It is a very contagious illness that can spread to members of your family and other people who have close physical contact with you. With proper treatment, the rash and intense itching of scabies usually begin to subside within one to two days, although some milder itching can persist for a few weeks.

Your doctor can treat scabies with various topical (applied to the skin) medications, including permethrin (Nix, Elimite), lindane (Kwell, Scabene), crotamiton (Eurax), and, in infants and other sensitive people, sulfur in petroleum. The choice of a specific medication is influenced by a person's age, pregnancy, the presence of coexisting skin conditions, and medical history. Scabies medications usually are applied from neck to toe after bathing, allowed to remain on the skin for eight to 14 hours, and then washed off. In some cases, a second application is necessary, depending on the type of medication used and your symptoms. Ivermectin (Stromectol) is an oral medication that also treats scabies effectively. It is given as a single oral dose followed by a repeat dose two weeks later.

Hope this helps - all the best, sue
