A rash from dust mites appears due to an allergic reaction, and to treat it, a doctor may suggest allergy medications or immunotherapy, according to Mayo Clinic. Some of the medication options include antihistamines and corticosteroids. There are also ways to lower the risk of dust mites in the home such as vacuuming more often and washing the bedding every week.
Antihistamines are medications that help to reduce the chemical from the immune system that causes itching from dust mites, explains Mayo Clinic. These medications may also help to eliminate other symptoms from a dust mite allergy including running nose and sneezing. Examples of these medications include Allegra, Claritin, Alavert and Zyrtec. These are over-the-counter medications, but there are prescription medications available include Astelin and Patanase.
Immunotherapy is another treatment option for rashes from dust mites, states Mayo Clinic. This method of treatment involves allergy shots, which the patient gets once to twice a week. The injection contains a very small dose of the allergen, in this case, dust mite protein, and the doctor increases the dose gradually over time, usually during a three- or six-month period. Following this, the patient must get a maintenance shot every four weeks for a few years. Doctors recommend this treatment when other treatments do not work.
