House Dust Allergy

• The allergen is a MITE and not a dust
• Mites are 8 legged insects (Arachnids)
• Mites feed on human skin peelings (dandruff)
• Mites mainly live in bedrooms
• In the bed
• In the carpet
• Mites are most active in bed with us at night
• We are allergic to their feces
• Their numbers increase with rising humidity
• House dust allergy is a year round allergy (Often worse in winter)
• Mites mainly cause a stuffy nose
• Mites are an important cause of asthma

Diagnosis:
 • Don’t assume house dust allergy. Have an allergy skin test or blood exam

Management:
 • Encase the mattress, box springs, and pillow
 • Maintain room humidity below 50% (dehumidifier?)
 • Vacuum the carpeting regularly (Hepa filter attachment?)
 • Use a room air filter if warranted (commercial size is best)
 • Take non-sedating antihistamines as needed
 • Use intra-nasal steroids or Cromolyn spray every day.
 • Start allergy injection therapy if insufficiently improved.
