Crusted Scabies Treatment – Information and Treatment Options

Crusted scabies, formerly known as Norwegian Scabies, is a particularly severe form of scabies that can be difficult to treat. The reason this disease is challenging to treat is because thousands of mites (sarcopic scabiei mites) are often identified during a crusted scabies outbreak. Comparatively, during an outbreak of the common variation of scabies, only 10-12 mites are typically found. This article will provide some background information on this disease, and go over the most effective crusted scabies treatments.

At Risk Groups

Individuals who have compromised immune systems, such as HIV and cancer patients, are more susceptible to acquiring crusted scabies.

Additionally, people living in crowded conditions (particularly in developing nations) tend to acquire the disease at a much higher rate in comparison to the rest of the population.

Finally, elderly patients, particularly those living in nursing homes, may be more vulnerable to crusted scabies, as the immune system tends to weaken with age.

Crusted Scabies Symptoms

Crusted scabies is not usually nearly as itchy as normal scabies. The primary indications of the disease are scaly rashes and skin that has a “crusted over” appearance. This crusted-over appearance generally traverses the entire body. The mites can even make their way onto face and head of crusted scabies patients, which is something that almost never happens in cases of regular scabies.

Crusted Scabies Treatment

Ivermectin is generally the first-line treatment of crusted scabies. It is generally taken orally, but it can also administered intravenously. Two to five doses of ivermectin will, in about 70% of patients, eradicate the disease.

However, it is not a treatment option that is recommended for children under six. Other creams or combination therapies will be necessary in young patients.

Combining Ivermectin with a Scabies Cream

Scabies creams, such as permethrin and lindane, may also be prescribed as supplementary crusted scabies treatments. Combining ivermectin with one of these scabies creams is often a very effective combination treatment of crusted scabies. Permethrin is the cream that is most commonly used in unison with ivermectin, but there are alternatives, such as sulfur in petrolatum, benzoyal benzoate, and tea tree oil (related article: Scabies Treatment)


Crusted scabies treatment is not always a simple task, but in almost all cases, the disease can be eradicated. Ivermectin, combined with a scabies cream, such as permethrin, is perhaps the most potent combination-treatment of the irritating affliction.
