Anyone with asthma can have an acute severe flare-up. Causes include:

To help avoid acute severe flare-ups be sure to:
Identify and avoid those things that cause flare-ups or triggers.
Try to stay away from people who are sick with respiratory infections. Wash your hands often. And, talk with your health care provider about vaccines you should have.
If you have severe allergies, talk with your health care provider about seeing an allergist.
Take asthma medications as recommended by your health care provider.
If exercise is a trigger, make sure you use your quick-relief medication before you are active. Keep an inhaler in your purse, gym bag, or back pack.
Get medical treatment as soon as possible when your symptoms don't respond to your asthma medications.
