How are house dust mite allergies treated?

There are two main ways to treat house dust mite allergies.

The first is to try to lower the number of house dust mites in your home.

Here are some tips on how to do that

There are also medicines that may help. You can get some medicines over the counter, but others must be prescribed by a health care provider.

However, many of these medicines only help treat your dust mite allergy symptoms, not what causes them. There are some prescription medicines that can do more. In fact, they can actually help change the way your body reacts to house dust mites over time. This type of treatment is called “allergy immunotherapy” (im-mu-no-ther-a-py). There is allergy immunotherapy made just for house dust mite allergy.

Allergy immunotherapy is almost always prescribed by an allergy specialist.
