House dust mite allergy: therapy

If a house dust mite allergy is confirmed, treatment should be started immediately. The most important measure is to avoid contact with the allergen as much as possible. Antiallergic and anti-inflammatory drugs are available to alleviate acute symptoms. A causal treatment is possible with a specific immunotherapy.

Avoidance of allergens

Avoiding contact with house dust mites or with their excretion products leads to the relief of acute allergic complaints. For more information, see Allergen Avoidance.

How is drug therapy carried out?

Acute allergic complaints can be alleviated with antiallergic and anti-inflammatory drugs (symptomatic therapy). The underlying disease, however, does not improve. In order to achieve lasting treatment success, a causal therapy against the allergy is used - a type of vaccination, which is described by the technical terms "specific immunotherapy (AIT)", "desensitization" or "desensitization" ("make insensitive").

Symptomatic therapy

Allergen avoidance is always the most direct and effective way of treating an allergy. In contrast to other allergens such as pet allergies, this is not always possible with sufficient effectiveness in the case of house dust mite allergies. In cases in which allergen avoidance is not possible or not sufficiently possible, antiallergic and anti-inflammatory drugs alleviate the symptoms. Antihistamines block the allergic processes in the body and thereby reduce above all the itching and sneezing irritation as well as the runny nose. These are offered in the form of nasal sprays, (eye) drops, juice and tablets. New, modern active ingredients can

given in childhood. They should be taken in the evening. If the symptoms are stronger, corticoids (cortisone) are used for local application in the nose. In allergic asthma, corticoids are inhaled in combination with drugs that dilate the bronchi (betamimetics).

Allergen Specific Immunotherapy (AIT)

With allergen-specific immunotherapy (AIT), the immune system is trained until it has learned that the allergens are not dangerous. For this purpose, the allergy sufferer is given "his / her" trigger in increasing doses. The aim of the AIT is to bring the immune system back into its natural balance. The treatment takes about three to five years, and the chances of success for house dust mite allergies are 80 to 90 percent. There are two ways to administer the allergen extracts:

  • Sublingual immunotherapy: The mite allergens are given under the tongue once a day all year round in the form of tablets or drops. This treatment can be carried out at home as prescribed by a doctor. Side effects are tongue and palate itching as well as slight swelling of the mucous membranes, sometimes more severe in the upper gastrointestinal tract such as increased reflux. Often the symptoms improve after a year of treatment.
  • Subcutaneous immunotherapy: the allergens are injected into the upper arm by the doctor. In the dosing phase, injections with increasing allergen concentration are administered weekly. If the maintenance dose is reached after a few weeks, the patient receives one injection of this dose from the doctor every month. He / she then has to stay in the doctor's office for at least 30 minutes, as this form of therapy can rarely lead to an intensified reaction or, very rarely, an anaphylactic shock (probability 1: 20,000). In addition, alcohol consumption and strenuous physical exertion should be avoided on the days of treatment.

Whom can I ask?

The diagnosis and therapy of house dust mite allergies are carried out by a specialist doctor trained in allergology (for children, ENT, skin or lung diseases) and in special facilities such as an allergy ambulatory.

How are the costs going to be covered?

The e-card is your personal key to the benefits of the statutory health insurance. All necessary and appropriate diagnostic and therapeutic measures are taken over by your responsible social insurance agency. A deductible or contribution to costs may apply for certain services. You can obtain detailed information from your social security agency. Further information can also be found at:
