According to a 2012 study at the Johns Hopkins Allergy and Asthma Center, people who had COPD and seasonal allergies experienced worsened respiratory symptoms such as coughing and wheezing.
They were also significantly more likely to need medical attention for their symptoms.
COPD: An overview
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions usually made up of chronic bronchitis and emphysema. COPD is commonly linked to a history of smoking cigarettes.
The condition results in airway blockages and mucus production, often causing serious breathing difficulties. Symptoms include:
  • persistent cough
  • wheezing
  • fatigue
  • shortness of breath
  • feeling winded after activities that weren’t difficult in the past
  • coughing up mucus

Why do I have seasonal allergies?

Seasonal allergies are very common. Millions of people deal with the itchy, watery eyes and stuffy noses that seasonal allergies cause.These symptoms occur when your immune system reacts to allergens you’ve inhaled such as:
  • pollen
  • dust
  • mold
  • animal dander
Your immune system activates certain cells that produce substances, including histamine. These substances produce allergy symptoms.
People with COPD seem to be more sensitive to other breathing conditions. Of course, if you have COPD, you likely already have some trouble breathing.
How can I avoid serious complications?
The best thing you can do is to avoid potential allergens.
Allergens are all around us, but you already have a head start if you know your triggers. You can take steps now to reduce your contact with specific allergens that worsen your symptoms.
Read on for tips on avoiding common allergens that could make your COPD symptoms worse.

Know before you go

Check out your local pollen report before you leave the house. Many weather sites, such as AccuWeather, will provide information on the current pollen and mold levels for your area.
The Weather Channel’s Allergy Tracker also notes the levels for particular types of pollen, including:
  • trees
  • weeds
  • grasses
You may wish to plan outings on days when pollen and mold levels are lower to reduce your allergy symptoms.

Stay inside

It’s best to stay inside when the air quality in your area is poor. For people with COPD, an Air Quality Index above 100 can wreak havoc on respiratory symptoms.
If you live in the United States, a good resource for checking air quality is AirNow, which measures the amount of air pollution in a given area. If you have to go outside, try wearing a mask to filter out pollutants and irritants.

Treat your symptoms

When you have allergy symptoms, such as itchy eyes or a runny nose, talk to your doctor about allergy medication. Taking an over-the-counter antihistamine may work for you.
Medications such as diphenhydramine (Benadryl) and cetirizine (Zyrtec) can stop your immune response to allergy triggers in its track, potentially lessening breathing difficulties.
Nasal steroids, decongestants, and inhalers may also be needed to decrease inflamed airways.

Allergy-proof your environment

Whenever possible, try to take measures to keep allergens out of your space. Here are some things you can do at home:
  • Install a good filtration system in your air conditioner.
  • Keep windows closed when pollen counts or pollutants are high.
  • Buy a cabin air filter for your car that’s specifically designed to keep allergens out.
  • Vacuum and dust regularly to get rid of any pollen or mold spores that may have gotten in from outside.

Talk to your doctor
Talk to your doctor about your allergy symptoms and how seasonal allergies affect your COPD. They may suggest a variety of options, which could include:
  • trying a prescription allergy medication
  • using your inhaler more often during peak allergy season
  • getting an allergy test to see which allergens are causing your reactions
  • trying allergy shots (immunotherapy) to reduce allergy symptoms
