COPD Flare-Ups - Topic Overview

When you have COPD, especially if you have chronic bronchitis, you may sometimes have sudden attacks where your breathing and coughing symptoms suddenly get worse and stay that way. These attacks are called COPD exacerbations, or flare-ups.

With treatment, many people recover and return to the same level of shortness of breath they had before the attack.

These attacks may be life-threatening. If your symptoms suddenly get worse, and if taking your medicine doesn't help, have someone take you to the emergency room. Call 911 if needed.

COPD attacks often occur more frequently, last longer, and are more severe the longer you have COPD.


The two most common causes of a COPD attack are:1

Having other health problems, such as heart failure or an abnormal heartbeat (arrhythmia) may also trigger a flare-up. In some cases, the cause is not known.

Here's what happens during an attack:

  • Your lungs may suddenly produce more mucus. Or the airways of your lungs (bronchial tubes) may suddenly get narrower.
  • These two things reduce the airflow in your lungs.
  • And that makes it harder to breathe and makes your coughing worse.


In a COPD attack, your usual symptoms suddenly get worse:

  • You have more shortness of breath and wheezing.
  • You have more coughing, with or without mucus.
  • You may cough up more mucus than usual, and it may be a different color.

Some people also have a fever, insomnia, fatigue, depression, or confusion.


Treatment of a COPD attack depends on how bad it is. It may involve several visits to your doctor's office or clinic. Or you may need to be treated in the hospital.

To treat COPD attacks, experts recommend:

  • Quick relief (short-acting), inhaled bronchodilatorsinhaled bronchodilators, which are medicines that relax the bronchial tubes and make it easier to breathe. These medicines may include:
  • Oral corticosteroid medicines, which reduce the swelling in your airways and may make breathing easier. They are typically given for 5 days to up to 14 days to those who aren't already taking them as part of their long-term treatment.
  • A machine to help you breathe. This is called mechanical ventilation. It is used only if medicine is not helping and you are having a very hard time breathing.
  • Oxygen, to increase the amount of oxygen in your blood.
