Asthma is a long-term breathing problem. Your child may have a lot of attacks with wheezing (a high-pitched whistling sound when the child breathes) and coughing. It can be hard for your child to breathe. Asthma attacks can be triggered by exercise, cold viruses, cold air, strong emotions, and smoke. Attacks can also be caused by pollens or animal dander.
Long-term control medicine (also called controller): This medicine helps prevent asthma attacks.
Quick-relief medicine (also called rescue medicine): If your child is having asthma symptoms (wheezing, coughing, trouble breathing), he should take his quick-relief medicine.
