10. What Do I Do If I Have an Asthma Attack?

An asthma attack is a sudden worsening of asthma symptoms caused by the tightening of muscles around your airways (bronchospasm). If you are experiencing an asthma attack, follow the "Red Zone" or emergency instructions in your asthma action plan immediately. If you have trouble breathing, walking, or talking or have blue lips or fingernails, call 911.
