What are the treatment options for house dust mite allergy?

House dust mites live mainly in bedding, mattresses, carpets, and upholstered furniture. Allergy symptoms can include sneezing, blocked or runny nose, itchy eyes, cough, wheeze, or worsening eczema. Treatment aims to reduce contact with allergens and calm inflammation in the nose, eyes, or airways.

A clinician may recommend [Allergy Testing](/treatments/diagnostics-and-screening/allergy-testing/) if symptoms have several possible triggers. The result is interpreted alongside your pattern of symptoms; a positive test alone does not explain every episode.

Use mattress and pillow encasements, wash bedding regularly at a hot temperature suitable for the fabric, and keep the bedroom dry and well ventilated. Reduce carpets, heavy curtains, and fabric clutter where practical. Cleaning with a suitable vacuum and damp dusting can limit particles becoming airborne.

[Allergy Medication](/treatments/medical-management/allergy-medication/) may include antihistamines, nasal sprays, or eye drops. Use products as directed and ask about technique, especially for nasal sprays. If symptoms remain troublesome, discuss whether an allergy specialist should review longer-term options.

Arrange medical advice for persistent wheeze, night-time cough, reduced exercise tolerance, or symptoms that keep returning despite treatment. Seek urgent help for severe breathlessness, difficulty speaking, blue lips, faintness, or rapidly worsening swelling of the lips or tongue.

Do my symptoms fit dust mite allergy or another condition? Should I have allergy testing? Which medicine suits my symptoms and other health conditions? How should I use a nasal spray? Could I also have asthma or eczema needing a separate plan?
