To treat dust mite allergies, doctors generally recommend reducing exposure to dust mites and taking allergy medications, such as antihistamines, corticosteroids and decongestants, according to Mayo Clinic. Other possible treatments are immunotherapy and nasal irrigation.
To reduce the presence of dust mites, use allergen-proof covers for mattresses and pillows, and wash bedding in hot water every week to kill dust mites, suggests Mayo Clinic. It also helps to maintain a low humidity below 50 percent, use a wet mop to remove dust, vacuum frequently and remove dust mite habitats, especially carpeting. Additionally, install an efficient media filter to the furnace and air conditioner, and turn on the fan to produce an air filter for the entire home.
Antihistamines are allergy medications that alleviate a runny nose, sneezing and itching, while corticosteroids control inflammation and hay fever symptoms, explains Mayo Clinic. While decongestants promote easier breathing, avoid using decongestant sprays consecutively for more than three days to avoid aggravating nasal congestion.
Cromolyn sodium often works effectively when used before allergy symptoms manifest, notes Mayo Clinic. If other allergy treatments do not provide relief, doctors may recommend immunotherapy, which involves training the immune system to become less sensitive to allergens through allergy shots. Another option is nasal irrigation, which requires the use of a special squeeze bottle and saltwater rinse to remove thick mucus and sinus irritants.
