According to the Mayo Clinic, living comfortably with dust mite allergies often involves a combination of medical treatment and household changes. Antihistamines affect the immune system to reduce itching, sneezing and runny nose, nasal sprays with corticosteroids decrease inflammation, and decongestants shrink swollen tissues inside the nose. Cromolyn sodium nasal spray and leukotriene modifier tablets limit the immune system response.
The Mayo Clinic notes that dust mite allergies can be treated with immunotherapy, which involves injections to desensitize an individual to an allergen. Weekly shots gradually decrease to monthly injections, which are needed for three to five years. Nasal irrigation with salt water helps to clear mucus and irritants out of nasal passages.
In the home, the Mayo Clinic advises people who are sensitive to dust mites to use allergen-proof covers on their mattresses, box springs and pillows and to wash sheets, blankets and pillowcases once a week in hot water at a temperature of at least 130 degrees Fahrenheit to kill mites. Use of dehumidifiers and air conditioners keeps humidity low. Any stuffed toys must be kept off the bed and washed regularly in hot water. Clutter, such as knickknacks, books and magazines, collects dust mites and is best eliminated from the bedroom. Carpeting is a good environment for dust mites and should be removed. Finally, a high-efficiency media filter should be installed in the furnace and air conditioning unit and changed every three months to keep home allergen levels low.
