Asthma: Limit asthma attacks caused by colds or flu

Respiratory infections, such as colds and the flu, are one of the most common causes of asthma flare-ups, especially in young children. A stuffy nose, sore throat, cough, fever, or other signs and symptoms caused by a cold or flu (influenza) virus can be a nuisance. But if you have asthma, even a minor respiratory infection can cause major problems. Asthma signs and symptoms, such as wheezing and chest tightness, may not respond as well to regular asthma medications. Also, asthma symptoms caused by a respiratory infection may last for several days to weeks.

There's no sure way to keep yourself or your child from getting a cold or the flu. But taking steps to avoid getting sick — and taking the right steps when you do — can help.

Preventing colds and the flu

Take these steps to help you avoid getting sick:

  • Get an annual flu shot unless your doctor recommends against it. Most adults and children older than 6 months old should get a flu vaccination every year. If you do get a vaccination, you'll need a shot (injection), since nasal spray vaccinations, such as FluMist, aren't recommended for people with asthma. You or your child may need vaccinations for more than one type of flu virus.
  • Ask your doctor if you need a pneumonia vaccination. Most people need to get this vaccination only one time, but in some cases a booster shot is needed.
  • Avoid contact with anyone who's sick. Germs that cause respiratory infections are easily passed from person to person.
  • Wash your hands often. This kills the germs that can cause respiratory infections. Carry a bottle of hand sanitizer to kill germs while you're on the go.
  • Avoid touching your eyes, nose and mouth. These are the points where germs that can make you sick enter your body.
  • Stay in shape. Regular exercise may help you avoid getting sick.

What to do when you do get a cold or the flu

Despite your best intentions to stay healthy, an occasional cold or case of the flu is inevitable — especially in children. These steps may help:

  • Call your doctor if your asthma begins to flare up when you're sick. If you have the flu, early treatment with an antiviral medication or other prescription medication may help ease symptoms and may help you recover more quickly.
  • Follow your asthma action plan. If you notice warning signs of an asthma attack — such as coughing, wheezing, chest tightness or shortness of breath — adjust your medication as directed by your written asthma action plan. (If you don't have an asthma action plan, talk to your doctor about making one.)
  • Rest and take care of yourself. Rest and drink plenty of fluids. With your doctor's OK, use over-the-counter cold or flu remedies to relieve your symptoms. These medications won't help you get over the cold or flu faster, but they can help you feel better in the meantime.
  • Monitor your airflow. Use a peak flow meter to monitor how well your lungs are working from day to day. Take your readings at the same time every day. If you notice a drop in your peak flow rate, adjust your medication as directed by your doctor.
  • Seek help right away for severe symptoms. Seek treatment if you have severe breathing trouble or if your throat is extremely sore. Also get medical attention if you have any signs or symptoms of pneumonia, such as a high fever, chills, sweats, sharp pain when taking deep breaths or a cough that brings up colored phlegm.
  • Stay home. If you do get sick, stay home from school or work to avoid infecting others. Cover your mouth and nose with a tissue when you cough or sneeze. Generally, you can infect others a day before your symptoms appear and for up to a week or so afterward.

Work with your doctor to develop a plan of action to prevent getting a cold or flu, and know what to do at the first signs you or your child may be getting sick. Prompt treatment can help ease symptoms and prevent a mild asthma flare-up from progressing to a severe asthma attack.
