Respiratory Infections

Respiratory infections include the common cold, the flu and other infections. These common illnesses can affect your lungs when you have asthma. They can cause inflammation (swelling) and narrowing of your airways. These changes could trigger asthma symptoms (an asthma episode or an asthma attack).

What Do I Do If I Have a Respiratory Illness?  

It’s always important to keep your asthma under control. It is particularly important when you’re sick.

  • Follow your asthma action plan. Be sure that your asthma action plan tells you what to do in case of illness. If you get flu-like symptoms, see your doctor right away.
     
  • Talk with your doctor about what over-the-counter medicines to use for a respiratory infection.
     
  • Keep your quick-relief medicine with you at all times to treat asthma symptoms.
     
  • Call your doctor if you have any symptoms that concern you.
     
  • Call 911 immediately if you have any of these danger signs:
    • Trouble walking or talking due to shortness of breath
    • Blue or gray lips or fingernails
    • Fast breathing with chest retractions (skin sucks in between or around the chest plate and/or rib bones when inhaling)
    • Other signs of a severe asthma attack

How Can I Prevent Respiratory Infections? 

Viruses cause most respiratory infections. To lower your chance of getting sick, take these steps:

  • Wash your hands often with soap and warm water.
  • Avoid touching your eyes, nose or mouth.
  • Get a yearly flu vaccine.
  • Keep your breathing equipment clean. This includes your asthma inhaler, asthma nebulizer, and nebulizer tubing and mouthpiece.
  • Do not share your breathing equipment or medicines with others.
