Dust is a complex substance that contains many individual allergens, including pollen, mites, fungi, and other things. Basic cleaning efforts, such as keeping the house well swept and also eliminating sources of dust (such as pets and carpet) are all part of managing the allergy. Additionally, your doctor
will likely prescribe some helpful medications, which could include antihistamines as well as nasal steroid sprays. However, if these measure do not work then it is likely worthwhile to perform allergy testing with an allergy doctor so that you can better determine which component of the dust you are allergic to. This will help you to focus your cleaning and other efforts. For example, if the allergy testing shows that you are allergic to dust mites, then mattress covers will help a lot. As always the diagnosis and the management of your particular concern will require a physical examination by your personal physician. Setting up an office visit with your primary care doctor
is highly recommended.
