What should you know about home dust mite allergy?

Dust mites live in household fabrics such as bedding, mattresses, carpets, and upholstered furniture. People with this allergy may notice symptoms after sleeping, cleaning, or spending time in dusty indoor rooms. Common presentations include repeated sneezing, a runny or blocked nose, itchy eyes, and an itchy throat; some people also develop cough or wheeze.

Symptoms can overlap with a viral infection or other allergies, so timing and triggers matter. Allergy testing may help identify whether dust mites are responsible. Dust mite allergy can also aggravate asthma symptoms in people who have asthma.

Wash bedding regularly as advised by your clinician, use allergen-resistant covers if recommended, and reduce fabric clutter where practical. Ventilate rooms, control dampness, and clean surfaces in a way that does not send dust into the air. A well-fitting mask may help during cleaning if dust triggers symptoms.

A pharmacist or clinician can explain suitable treatments for nasal or eye symptoms. Do not use a medicine longer or more often than its instructions allow, and seek advice if symptoms continue despite home measures.

Seek urgent help for severe wheezing, rapidly worsening breathlessness, difficulty speaking in full sentences, blue or grey lips, or swelling of the mouth or throat. Arrange a routine review if blocked or runny nose, itchy eyes, or cough repeatedly disrupts sleep, work, or exercise, because treatment and allergy testing may need adjustment.

Ask whether your pattern fits dust mite allergy, whether allergy testing is useful, which bedroom changes are realistic, and how to recognise an asthma flare.
