Learn About Asthma Triggers
People with asthma have overly sensitive air passages. Common things that cause little or no trouble for most of us can leave people with asthma struggling for breath. Substances or conditions that bring on asthma attacks in certain people are called asthma triggers. Primatene® MIST is not intended to treat the cause of asthma symptoms. But avoiding the causes of your asthma can help you keep your asthma under better control. Asthma symptoms have two common types of causes:
A. Allergic triggers: Allergens (things that cause allergic reactions) most often cause asthma symptoms by entering the lungs as you breathe. An asthmatic person may be allergic to one or more common allergens found in the environment.
The following are common allergens:
- Indoor or outdoor molds, pollen
- Animal dander (flakes from the skin, hair, or feathers of any warm-blooded pet, including dogs, cats, birds, rodents, and horses)
- Dog hair and saliva
- Cat hair and saliva
- Dust mite particles (from microscopic insects present in house dust)
- Cockroach particles
- Sulfites used as a preservative in some foods and beverages, such as olives and wine
- Certain medications such as penicillin or aspirin
Some allergies are easy to identify, like cat dander and pollen; others are harder to identify, such as house dust. Your physician can identify possible allergic triggers by asking detailed questions or through skin testing.
B. Non-allergic triggers: These have nothing to do with allergies, but cause the same airway changes as allergic triggers (i.e., airway swelling, mucus increase, and airway narrowing).
Materials (irritants) in the air:
- Tobacco smoke
- Wood smoke, pine odors
- Room deodorizers, fresh paint, household cleaning products, cooking odors, perfumes and cosmetics
- Chemical fumes, outdoor air pollution (smog, exhaust from cars and buses, smoke from factories and power plants), natural gas, propane or kerosene
- Heating units (using gas, wood, coal or kerosene)
- Respiratory infections–common colds, the flu, or sinus infections
- Exercise
- Cold air or sudden changes in weather/air temperature-cooling, storm fronts, high humidity
ENVIRONMENTAL TRIGGERS
Discuss with your doctor how to identify the allergens or irritants that affect you, and determine which actions are going to be most helpful in reducing your asthma symptoms.
