For a child with exercise-induced asthma, when should a bronchodilator be used?

Using a bronchodilator before exercise for a child with exercise-induced asthma is considered the best practice. This approach helps to open up the airways and prevent bronchospasms that can occur during physical activity. By administering the bronchodilator prior to exercise, it allows ample time for the medication to take effect, resulting in improved airflow and reduced symptoms such as wheezing, coughing, and shortness of breath during physical activity.

It's important to recognize that physical exertion can trigger asthma symptoms in susceptible individuals, so proactive management is crucial. The bronchodilator works by relaxing the muscles around the airways, leading to easier breathing, which is particularly beneficial for children participating in sports or other physical activities.

Administering the medication after exercise or only during an asthma attack does not provide the preventative benefit necessary to effectively manage symptoms during exercise. Furthermore, relying solely on a doctor's orders implies a more reactive than proactive approach, which might not adequately prepare the child for exercise-induced complications. Therefore, the recommended practice emphasizes the importance of preemptive care in managing exercise-induced asthma effectively.
