Asthma and Allergy

Allergy is a common asthma trigger. Your doctor or pharmacist can help you to identify allergens. Your doctor can also do special tests for allergies. Some common allergens are: 

House Dust Mite: If you are allergic to dust mite, you should consider ways to reduce house dust mite in your home. 

• Encase mattress and pillows in mite-proof covers. Your pharmacist can advise on this. 
• Wash bedclothes weekly in hot water (over 55°). 
• Shake and air pillows and quilts in the sun weekly. 
• Remove soft furry toys and soft furnishings, if possible. Soft toys can be placed in the freezer overnight to kill dust mites. 
•  Helpful suggestions for cleaning: 
  • wear a mask 
  • dust with a damp or electrostatic cloth 
  • use a wet or electrostatic mop rather than vacuum 
  • consider ducted or well-filtered vacuum-cleaning systems 
  • ask about low allergen housing. 

Pollens: If you are allergic to pollen, it is difficult to avoid it but try these measures. 

• Find out about grasses and trees in your area which have wind-borne pollens and avoid them. 
• Keep windows and doors closed on windy Spring days and avoid outdoor activities. 
• Avoid mowing the lawn, or wear a mask and eye protection. 
• Have native plants which have little pollen in your garden. 
• Ask your doctor about antihistamines. 

Pets: Anyone affected by allergens from animals, especially cats or birds should 

• avoid close contact 
• keep pets out of the bedrooms, preferably out of the house. 

Moulds: If mould spores trigger your asthma 

• air the house well 
• keep air-conditioning units clean; evaporative coolers are not recommended 
• indoor plants may need to be removed 
• avoid disturbing rotting vegetation such as mulches and composts, especially in hot, humid weather 
• be cautious about going outdoors on warm, windy days, and avoid or take protective measures during grass-cutting or harvesting.
