Does you child wheeze, cough, or seem very out of breath after exercise? He or she may have exercise-induced asthma (or exercise induced bronchoconstriction). This is relatively common condition, and one that if addressed correctly should allow your child to tolerate exercise and continue to play sports.
First step is to see your physician and make the diagnosis.
Albuterol (ProAir, Ventolin, Proventil- brand names) or Levalbuterol (Xopenex) are rescue inhalers. These inhalers help open up your child’s airways quickly and stop cough/wheezing/shortness of breath/chest tightness. They can be used as needed IF asthma symptoms begin. If your child plays a competitive sport or child gets asthma symptoms EVERY time he or she does a particular activity or exercise THEN have your child use the rescue inhaler 15-20 minutes before strenuous exercise and see whether this prevents the symptoms from happening.
IF even with rescue inhaler use prior to sports your child continues to have asthma symptoms, THEN they should also start daily preventative treatment for asthma.
