Why Overusing an Inhaler Is Dangerous
Inhalers can be a lifeline for people with asthma. When coughing, wheezing, or shortness of breath occurs, a quick hit of a bronchodilator can often make those symptoms go away.
In particular, the medications known as short-acting beta2-agonists (a type of bronchodilator) can provide quick relief from asthma symptoms—but they can also be damaging if they are used too often. Using short-acting beta2-agonists too often is a sign that asthma is out of control.
