Treatment of Dust Mite Allergy
The most important step is to avoid dust mites as much as possible. Limiting your exposure to dust mites will reduce your symptoms. However, it’s nearly impossible to completely get rid of dust mites in your environment. You may also need medicines to control symptoms.

Certain over-the-counter and prescription medicines may help reduce dust mite allergy symptoms.

Antihistamines are available as pills, liquids or nose sprays. They can relieve sneezing and itching in the nose and eyes. They also reduce a runny nose and, to a lesser extent, nasal stuffiness.

Nasal corticosteroids are a type of nose spray. They reduce swelling in your nose and block allergic reactions. They are the most effective medicine type for allergic rhinitis because they can reduce all symptoms, including nasal congestion. Nasal corticosteroids have few side effects.

Leukotriene receptor antagonists block the action of important chemical messengers (other than histamine) involved in allergic reactions.

Cromolyn sodium is a nose spray that blocks the release of chemicals that cause allergy symptoms, including histamine and leukotrienes. This medicine has few side effects, but you must take it four times a day.

Decongestants are available as pills, liquids, nose sprays or drops.
They help shrink the lining of the nasal passages and relieve stuffiness. Use decongestant nose drops and sprays only for a short time. Oral decongestants can cause side effects such as sleeplessness and increased blood pressure in some people. Consider checking with your doctor before using them.

Many people with a dust mite allergy do not get complete relief from medicines. This means they may consider immunotherapy (allergy shots). Immunotherapy is a long-term treatment that can help prevent or reduce the severity of allergic reactions. It can reduce the course of allergic disease by changing your body’s immune response to allergens.

Allergy Shots - Subcutaneous Immunotherapy (SCIT) is an effective treatment that has been around for more than 100 years. SCIT is a series of shots that have progressively larger amounts of allergen. An injection of the allergen goes into the fat under your skin about once a week during the initial phase of treatment. Many patients get complete relief of their allergies after being on SCIP for one to three years. Many physicians will continue SCIT for a period of five or more years. SCIT can provide long-lasting symptom relief. Many people experience benefits for at least several years after the shots stop.

Sublingual (under-the-tongue) immunotherapy (SLIT) is a way to treat dust mite allergies without injections. Patients put small doses of an allergen under the tongue. This exposure improves tolerance to the dust mites and reduces symptoms.
