Doctors recommend several medications for the treatment of dust mite symptoms, including antihistamines, decongestants, leukotriene modifiers, corticosteroids and leukotriene modifiers, according to Mayo Clinic. Other therapies for the symptoms include nasal irrigation and immunotherapy. Dust mite symptoms are usually similar to those of pollen allergies, such as sneezing, a runny nose and watery eyes.
Antihistamines work by limiting the production of an immune system chemical, which is usually active in allergic reactions, says Mayo Clinic. These medications help to ease a runny nose, sneezing and itching. Patients use corticosteroids as a nasal spray to control the symptoms of hay fever and reduce inflammation; examples include mometasone furoate, fluticasone propionate and triamcinolone. Taking decongestants eases swollen tissues in the nasal passages, making breathing through the nose easier; however, patients suffering from high blood pressure should not use oral decongestants because they increase blood pressure.
Leukotriene modifiers inhibit the activity of certain chemicals, while cromolyn sodium stops the immune system from discharging a particular chemical, explains Mayo Clinic. A patient may receive a series of allergy shots known as immunotherapy to help reduce the sensitivity of the immune system to allergens. Nasal irrigation involves the use of prepared saltwater rinse to remove irritants and mucus from the sinuses.
